THK LR & LR-Z Series LM Roller
The THK LR & LR-Z Series LM Roller is a compact linear motion roller designed for high-load, finite-stroke applications. Its rollers circulate along a precision-ground raceway, while the guide structure helps maintain smooth, stable motion.
The LR-Z Series uses a different retainer structure and is available with a UU seal option; the UU-sealed configuration is not available for the standard LR models without the Z designation. The series covers 15 to 50 mm widths, with basic dynamic load ratings from 21.6 to 285 kN and basic static load ratings from 39.9 to 577 kN, depending on the model.
