  • 5 Installation Tips for Grease-Free Sliding Linear

    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. With hybrid bearings, 120 pounds would be achievable as a radial load with a 25-pound push-force limit.
