THK LRA & LRA-Z Series LM Roller
The THK LRA & LRA-Z Series LM Roller is a compact linear roller designed for high-load linear motion in precision machinery. It is mounted using SM or SE fixtures, allowing the roller to fit into a mounting groove while keeping the overall installation compact.
The series includes LRA and LRA-Z configurations, with models from 15 to 50 mm width. Basic dynamic load ratings range from 21.6 to 285 kN, while basic static load ratings range from 39.9 to 577 kN, depending on the model. The LRA-Z version supports a UU seal configuration, and is not available on the standard LRA without the Z designation.
