Linear Rotary Bearings | anti-friction motion bearings
2021-5-14 · The rotational motion of the shaft causes the balls to flow much like a typical rotary bearing. In an application where only linear motion exists, the movement of the balls on and off the races creates a torque on the retainer. The torque is unbalanced, meaning that the retainer is free to rotate. This causes the retainer to creep or rotate slightly due to the linear motion of the …
