Linear ball bushings have a linear working direction and can be used for horizontal or vertical linear movements. Therefore, our linear ball bushings can be used in almost all industries. Since linear ball bushings are intended only for axial movement, rotational use would lead to premature fatigue or destruction of the ball bushings. For rotary movements, we therefore recommend ball cage guides, which enable not only infinite linear movements (stroke-limited) in addition to infinite rotary movements.
Common applications are lifting mechanisms or guides for cylinders. The ball bushings are also a good variant for additional guide. In addition, these linear ball bushings are often found in 3D printers, metering systems, measuring devices, positioning and alignment devices, bending devices and sorting systems.
For systems with increased particle development (e.g., dust and other abrasive particles), the linear systems should be protected with covers or bellows. The ingress of particles leads to a clumping of the lubricating grease or to significantly increased abrasion. By clumping the grease, the balls block in the ball circulation, which results in unscheduled maintenance.
