Linear bearing

grabcad

Linear bearing refers to a type of bearing that is designed to support loads along one axis, while minimizing friction and play between moving parts. It consists of a cylindrical sleeve, typically made from a hardened steel alloy or other durable material, which is mounted on a shaft or rod. The sleeve is often lined with a layer of lubricant or coated with a low-friction surface to reduce wear and tear. Linear bearings are commonly used in applications where smooth motion and minimal vibration are critical, such as in precision machinery, medical equipment, and high-speed manufacturing systems.
