SBR-LUU series linear bearing blocks are long-type linear bearing units designed for smooth linear motion, stable guidance and enhanced support in industrial equipment and automation systems.
Built with a durable aluminum housing and integrated long linear bearing, our SBR-LUU blocks provide low friction, stable running performance and increased support length for demanding linear motion applications.
We manufacture SBR-LUU linear bearing blocks in a wide range of shaft sizes. When replacing an SBR-LUU block, verify the shaft diameter, supported-rail profile, overall housing dimensions, mounting-hole spacing and block length. The longer housing changes the mounting footprint compared with standard-length SBR blocks, so matching shaft diameter alone is not enough. Standard sizes, drawing-based OEM requirements and bulk orders are available directly from our factory; send the model code, quantity and installation dimensions for confirmation.
Dimensions are in mm. Load ratings are in N. Weight is in g.
