Ball Corp.: Self-lubricating linear bushings

Offered in assorted styles, with straight or mini-flanged versions available, these new bushings are said to carry 3 times the rated life span of conventional bushings and are suitable as a low-maintenance solution for various applications. Performance centers on the design of the MX lubrication unit, which uses an integral fiber pad to deliver lubricant to the shaft surface through a capillary action, thus maintaining constant lubricating film between ball bearing and shaft. This is said to extend the maintenance interval on these linear bearings.
