The Bosch Rexroth SINGLE CAM BEARING LWA-052-SKS-FN-E-0 (R190315210) is a precision component designed for linear motion applications. This cam roller single bearing boasts an SKS format, which denotes a slimline width, short length, and standard height for compact integration into machinery. Constructed with an aluminum runner block body, it offers a standard load carrying capacity suitable for a wide range of uses. The economic accuracy class E indicates that this model has been optimized for cost-effectiveness without compromising on performance. This runner block is engineered without preservation or initial lubrication and does not include attachment elements on either the left or right front reference edges. It features an integrated lube nipple and comes in a standard version with the overall length of the runner block tailored to user requirements. The distance between runner blocks on table construction can be freely selected, providing flexibility in design. Featuring zero-clearance adjustment via socket hex screws located on the rear side of the runner blocks, this cam bearing ensures precision alignment. It is equipped with tough all-around sealing that delivers exceptional wiping action to maintain cleanliness and efficiency during operation. Grease lubrication is recommended to ensure smooth motion. The SINGLE CAM BEARING LWA-052-SKS-FN-E-0 is capable of handling maximum static loads due to resulting forces in both y and z directions (Fy max and Fz max respectively), as well as dynamic load capacities in y and z directions (Cy and Cz). It can operate effectively within a temperature range from -20°C to +80°C, accommodating various working environments. Designed for use with Rexroth's profiled rail systems sizes A, B, E, H, this cam roller guide provides versatility across different system sizes while offering self-aligning capabilities to compensate for any misalignments. With its robust design parameters—including dynamic and static torsional moments around multiple axes—it ensures reliable performance in handling and automation technology applications.

Advantage

The adjusting screws allow a zero-backlash run. By means of the adjusting screws, the carriage can be slightly rotated around the z-axis, or displaced in the y-direction, and therefore optimally aligned.
