Experience the fine and advanced stability in your devices by upgrading with our pro-grade cylindrical roller radial bearings. Carefully designed to deliver fine and smooth performances.
The cylindrical roller radial bearing assemblies are designed for very heavy radial loads. Each HJ bearing features two rows of precision rollers, held in place by flanges and a strong cage. This double-row design boosts stiffness and capacity. HJ bearings are often mounted without an inner ring (rollers run against the shaft). This provides a large bearing roller with a cylindrical contact area to support heavy loads. HJ bearings are ideal for applications where radial loads predominate. They handle much higher loads than ball bearings of the same size. The large rollers also help control radial roller bearing deflection. Unlike radial taper roller bearings, HJ cylindrical bearings focus on pure radial support, with no thrust capacity.
The Timken HJ-9211648 is a heavy-duty HJ series bearing built for large loads. It carries two rows of cylindrical rollers for added stiffness. This bearing is excellent for shafts of approximately 146.05 mm in diameter, where very heavy radial forces are present. With a short width (76.2 mm), it fits into compact housings.

Below are the key details of the cylindrical roller radial bearings – HJ series:
Our HJ bearings are made with high-quality chromium steel. This metal won't wear down or soften when it gets hot. Heat does not change how hard the steel is. Also, the material's bulk lets it soak up heat. This keeps the bearing stable even at high temperatures and stops hot spots from forming.
The HJ design includes oil channels and retention elements. The oil flows freely between the raceways and the rollers, which lets the heat escape. If the ring is used, the lubricant entrance holes are usually on the inside. This strong flow of oil cools the contact zones. Good lubrication makes the bearing work cooler.
The ends of the rollers in HJ bearings are crowned, which means they are slightly curled. Because of this, only the center makes a strong connection when there is stress. This shape spreads out the pressure evenly, so there is no tension at the edges.
HJ bearings have big rollers and thick rings. Metal's bulk makes it a good heat sink because it spreads heat out. The bearing's design absorbs and spreads out the heat that comes from use. The increased thermal mass slows down the rise in temperature, which protects the life of the bearing.
All of the parts of the slide move smoothly together. Even when a weight is added, the slide stays in line and works well.
Because they are machined to a very precise roundness, cylindrical roller radial bearings spin with very little run-out. Rollers that are perfectly fitted help keep vibrations low. The bearing will stay perfectly round no matter how fast you go. This regulated rotation makes sure that productivity stays high and products last a long time.
The strong flanges and double-row design keep the shaft from leaning. The bearing keeps the shaft on a straight path, even when strong radial forces are acting on it. Changes in load don’t have a big effect on alignment. This steadiness is what keeps the gears and wheels from wobbling.
Cylindrical roller radial bearings are made to be stiff so that they don’t shock as much. Balanced rollers and raceways evenly spread the weight. Because of this, the bearing doesn’t vibrate at all when it works. This is a big part of keeping noise and wear down in precision machinery.
The HJ series uses raceway curves that have been carefully honed to go along with the rollers. Every roller moves easily along its path because everything is perfectly lined up. Polishing surface treatments aims to lower micro-sliding.
A heavy-equipment OEM installed HJ-9211648 bearings in a new conveyor gearbox. After three months, vibration dropped by 30% and bearing life increased by over 50%. The improved radial cylindrical roller bearing alignment led to smoother operation and higher throughput. Project engineers noted that downtime was significantly reduced.

It’s the tiny gap between rollers and rings in a bearing. Cylindrical roller bearing radial clearance lets the bearing expand under heat. Too little clearance allows the rollers to bind; too much clearance enables the shaft to move too much. Cylindrical roller radial bearings are set with a specific clearance to maintain stiffness while allowing thermal growth.
Yes. Customized radial cylindrical roller bearings are often built to order. You can choose bore, OD, width, cage material, and roller count. Brands like Timken offer custom machining to fit unique shafts or housings. Custom options also include special steels or coatings for harsh environments.
Definitely, the HJ series itself is a double-row cylindrical roller bearing by design. However, many applications utilize single-row cylindrical roller bearings for simpler and lighter loads. Single-row bearings handle radial load in one direction. Double-row (like HJ) bearings handle larger radial loads and can also accommodate some moment loads.
Key factors are roller size and count, material, and tolerances. A double-row cylindrical roller bearing has roughly double the load capacity of a similar single-row bearing of the same size. The quality of the steel and the heat treatment also matter. HJ bearings use many rollers in two rows to maximize cylindrical roller bearing radial load capacity.
Follow the manufacturer’s fit recommendations. Typically, the outer ring gets a clearance fit or transition fit in the housing. Use proper shoulder support. Mount the unmarked end of the outer ring against housing the shoulder to clear fillets. Press the inner ring onto the shaft with controlled force. Always refer to the instruction sheet or CAD drawing (as on Timken’s CAD site) for dimensions.
They are used widely in automotive gearboxes, industrial gear reducers, motors, machine tools, and heavy equipment. Anywhere a cylindrical roller bearing supplier would supply high-capacity bearings. Applications include steel mills, mining conveyors, wind turbines, and ship engines. Their high stiffness and load-bearing ability make them ideal for rail wheels and cranes as well.
