THK’s Cross Roller Bearing RE SERIES represents a specialized linear motion component engineered for applications requiring outer ring rotation with exceptional precision and rigidity. This standard model features a unique crossed roller arrangement where cylindrical rollers are positioned at right angles to each other between the inner and outer rings, alternating direction in a single row. This configuration enables the bearing to simultaneously withstand radial, axial, and moment loads with high rotational accuracy and smooth operation. Manufactured with THK’s precision grinding technology, the RE SERIES ensures minimal runout and consistent performance under demanding conditions.

The technical features of the RE SERIES make it particularly suitable for applications where space constraints and performance reliability are critical. The compact design incorporates a single-piece outer ring and two inner rings, secured by a divider to maintain precise roller spacing and prevent skewing. This construction eliminates the need for additional components like holder rings or snap rings, simplifying installation while enhancing structural integrity. The bearings are available in various sizes with standardized dimensions, allowing for easy integration into existing machinery designs. Standard models come with pre-drilled mounting holes for straightforward fixation, and options include open-type or sealed variants to accommodate different environmental conditions.

Performance advantages of the THK Cross Roller Bearing RE SERIES stem from its optimized roller geometry and high-quality material selection. The crossed roller arrangement provides a large contact area, distributing loads evenly across the rollers to minimize deformation and extend service life. This design results in high rigidity, capable of maintaining accuracy even under heavy loads or high-speed rotation. The low friction coefficient ensures efficient operation with minimal heat generation, reducing the need for frequent maintenance. Additionally, the RE SERIES offers excellent positional accuracy, with tolerances tight enough to support precise indexing and repetitive motion tasks. For enhanced durability, THK employs vacuum-degassed steel and, in some models, surface treatments to resist corrosion and wear.

Typical applications for the RE SERERIES span multiple industries where rotational precision is paramount. In industrial machinery, these bearings are integral to rotary tables for machining centers, indexing units in automated assembly lines, and robot arm joints, where they facilitate smooth, accurate positioning. Within automotive systems, they are used in welding equipment turntables, engine testing apparatus, and precision gear mechanisms that demand reliable rotation under variable loads. In precision equipment, the RE SERIES finds use in medical device components like CT scanner gantries, semiconductor manufacturing tools including wafer handling robots, and optical instrument stages for alignment and inspection processes. Its versatility also extends to aerospace applications, such as antenna positioning systems and flight simulator actuators, where consistent performance under dynamic conditions is essential. By combining robust construction with advanced engineering, THK’s RE SERIES Cross Roller Bearing delivers the reliability and precision required for today’s high-tech industrial environments.
