Experience the most precious quality, THK BL Link Ball, accurately designed and manufactured for the high load capacity and noiseless performance. It always provides the top durability.
The THK LSP Linear Ball (LSP model) is a small, precision-engineered linear guide that works with very little friction. The slide has a very low friction coefficient because it has four hardened needle-roller raceways in which stainless steel balls roll. The rack-and-pinion cage in the middle of the device keeps the ball cage from sliding. This stops any loss of motion or backlash, even when the machine is going very fast or is in a vertical position. This machine doesn't need any maintenance because it is made entirely of metal and uses materials that resist corrosion, such as stainless steel and anodized aluminum. This layout lets THK LSP slides repeat on the micron scale, which is perfect for use with gears that need to be very precise.
Worn shafts make seals leak, waste oil, and stop machines without warning. SKF wear sleeves, fix these issues quickly with minimal effort. Here is why people like using them.
The LS 25150 is a ball slide with a long travel and an extra-long rail. Its longer stroke lets you push farther with each stroke. No matter how long it is, the movement is smooth and free of obstacles because there is little friction. Because it moves in a long, smooth line, the LS 25150 is great for use in labs and workshops.
Miniature ball slides, such as the LS 1077, work best in small spaces. Because it is only 10 mm tall and 19 mm wide, it fits where bigger guides can't. There is still a small built-in stopper to keep the ends of the cage from hitting each other. The LS 1077 has a 50 mm stroke and very little friction, which makes it easy to move back and forth quickly.
The 25125 LSP is a mix of THK's wide base and slipless cage design. With a 75 mm stroke, this model can move in many different ways while still being very stable. The slide's body is 66 mm wide and 25 mm high, which makes it hard to tip or bend. The pinion-and-rack cage's unbreakable grip keeps motion steady and accurate.
The LSP 25100 is a mid-size LSP slide with a 50 mm stroke and a 66 mm width. Its range and portability are well-balanced. These slides show the main benefits of the LSP series. They have a pinion-rack cage, low friction, and full corrosion protection.
Each THK LSP slide is made up of parts made of stainless steel and aluminum alloy. This item won't rust because its base and slider are anodized, and its balls and raceways are made of stainless steel. It is also water and sea-resistant.
The slide has a very low friction coefficient because it uses hardened and ground steel raceways and four rows of balls that go around in a circle. The rolling loss is very small, with a value of μ of about 0.0006–0.0012, because the balls touch the rails perfectly.
The LSP model has a pinion gear in the middle that works with a rack on the base. This makes it slipless compared to regular linear slides. The ball cage stays securely attached to the rail even when it is used vertically or when it is moving quickly, thanks to its smart design.
THK LSP slides are a technological marvel because they are both small and light without losing strength. Because it has a metal base and slider, this device doesn't have much inertia and is easy to speed up. The unit-type design is small, but it has all the parts that help it work in one pre-set module.
The recirculating ball cage is fully enclosed and has special oil grooves that make lubrication better. Also, the stainless steel construction keeps grease for a long time. We put oil on each slider ahead of time.

The LSP (Slipless Linear Ball Slide) doesn't slip at all because it uses a rack-and-pinion cage. Perfect for tasks that need to be very precise and not slide.
This linear ball slide is like a recirculating ball slide, but it has an internal stopper instead of a rack and pinion. Small and dependable for short trips.
The LSC, or linear ball slide with cylinder, has a pneumatic cylinder inside that lets it move on its own. The actuator and the slide are put together to save space.
THK LSP Linear Ball screws still give you accurate linear motion, even though they aren't slides. When you put them together with slides, they can move on their own. People usually call these systems "THK LSP linear ball screws."
Ball-bearing blocks help THK's linear guide rails (LM guides) move in a straight line, which is helpful for moving things over long distances or with heavy loads.
THK's direct-drive linear motors can move sliders without screws, which makes them perfect for some of the newest machines. Use them with THK slides for the best speed and accuracy.
If the standard sizes of THK LSP slides don't work for you, you can get them custom made. You can change the stroke length and slider size to fit the needs of your machine. THK can change the height and width of the slider by changing the block size. Most of the time, standard THK slides are made of stainless steel and aluminum. However, you can use coatings or special alloys (like anti-corrosion plating or ultra-hard surface treatments) to make them more durable in tough conditions. Custom Micron-Accuracy We can make THK LSP Linear Ball assemblies, motors, and ball screws, among other things.
THK has an online tool that can help you pick the best link ball model. You can use the Optimal Product Selection Tool to find a THK Link Ball or rod end bearing model that fits your needs by entering the load, orientation, and environmental variables. The tool also gives you CAD drawings and estimates of how long things will last. We've added an interactive size selector to help you pick the best THK series for your design. Engineers can use this free tool on THK's website to make it easier to choose products.
Slides guide the tool turrets, cutting heads, and carving mechanisms of CNC routers, mills, and lathes. They have low friction and high rigidity, which makes cutting more accurate.
Tools for the semiconductor industry include pick-and-place stages, inspection scanners, and wafer steppers. LSP slides are perfect for chip fabrication because they can repeat very small movements with great accuracy.
These slides let end-effectors and linear robots move smoothly in a straight line. Their small size and design that doesn't slip make them great for pick-and-place robots and assembly lines.
THK LSP slides are used in metrology and inspection for the axes of coordinate measuring machines and precision measurement machines that need to move in a way that is very repeatable and free of vibrations.
For lab automation (robots that pipette liquid, microscopes), it is important that things can move quietly and smoothly. LSP slides, which are commonly used in cleanrooms, keep things stable and clean.
Slides make it possible for packaging machines and printers to feed and handle materials correctly. The strong corrosion resistance is also good for food and chemical packing machines.
Linear slides are used in medical devices to place surgical robots and imaging equipment in exactly the right spot. Stainless steel is good for healthcare settings because it is easy to keep clean.
Both types give a smooth, strong, and long‑lasting surface for seals. Regardless of the size of your shaft, SKF has a sleeve that suits your needs.

THK LSP Linear Ball slides are engineered to retain grease and minimize maintenance. The ball cage features internal oil grooves that continuously supply lubricant to the balls, ensuring smooth operation. Stainless steel seals prevent dust and debris from entering the raceways. All metal parts have smooth, honed surfaces that evenly distribute oil. Because of this, each slide arrives factory-greased and typically never needs additional lubrication under regular use. These design choices prolong the maintenance interval by preventing oil loss. In practice, a THK LSP slide can go for years with no re-lubrication if properly installed.
For CNC machines and semiconductor tools, precision is paramount. THK LSP Linear Ball slides deliver exceptional repeatability in each stroke. The hardened, ground raceways and preloaded balls create a highly stable mechanism that returns accurately to the same position. Because the LSP cage has no slip, the slider stops and holds in place without shudder or drift. This results in sub-micron positioning accuracy, making tasks like wafer alignment or optical scanning consistently precise. Even when running at high speeds, the low inertia design prevents overshoot.
Both types give a smooth, strong, and long‑lasting surface for seals. Regardless of the size of your shaft, SKF has a sleeve that suits your needs.
The load is spread out evenly because the balls can spin freely in their grooves. Avoiding areas of high stress improves both accuracy and durability.
Needle rollers on the track touch the balls at certain points during optimal point-contact rolling. This setup makes movement easier by lowering the heat and reducing sliding friction.
The base and slider are both made to very tight tolerances. The wide base and strong materials keep the slide from bending, so the load stays on the right path.
All of the parts of the slide move smoothly together. Even when a weight is added, the slide stays in line and works well.
THK's reputation is built on decades of innovation. The first step in making a THK LSP Linear Ball is to come up with a new design. Engineers use computer-aided design (CAD) and motion simulation to make the ball's paths and cage shapes as good as they can be. Then, computer numerical control (CNC) milling and grinding are used to make the aluminum frame and hardened steel parts to very high standards. Every part, from the gear teeth to the drilled mounting holes, goes through strict quality control checks. Following ISO 9001 quality management standards and other industry certifications, every slide is made to exact specifications. THK has also shown that it cares about the environment by getting ISO 14001 certification.

Because THK LSP Linear Ball slides are already greased, you don't usually need to add more oil. The factory lubrication lasts a very long time because all the surfaces are sealed and made of stainless steel. You don't usually need to oil the slide again to use it.
THK slides are known for their incredible accuracy. A typical positional repeatability over a distance of 10 millimetres is about 0.010 millimetres. In other words, after each movement, the slider will always return to within about 10 microns of where it started.
Because they can be used in a lot of different ways, they are often used in systems that need smooth, precise movement, like robotic linear joints, automation stages in labs, and CNC machine axes. They are experts in many fields, including optics, inspection equipment, packing machines, and medical devices.
Yes. THK LSP slides are "unit-type" guides. The metal block holds everything, including the rails, balls, and cage. You don't need to do anything else to install the base; the slide is ready to use right away.
It hints at how precise the slides can be. With THK LSP slides, you can copy spots exactly to within a few microns. This is because their raceways are hardened and their tracks are narrow.
