  • Linear bearing - HIWIN GmbH - PDF Catalogs |

    If you choose a hybrid bearing, you can reduce the push-force by 0.5 pounds for every 10 pounds of radial load. Twenty-five pounds of push-force is the upper limit of an average person’s capacity. Therefore, with regular linear bearings, approximately 100 pounds of radial load would be the upper limit of a person’s capacity to push manually.
