Linear Ball Bearings

INA from Schaeffler linear ball bearings KH and linear ball bearing and housing units of the compact range have a small radial design envelope and are economical. Their low radial section height automatically makes them attractive for applications in which only a small amount of radial space is available.

The bearings have an outer ring with openings and contain a ball and cage assembly with a plastic cage. The outer ring is formed and hardened. The balls undergo return travel along the openings in the outer ring.

The bearings are available in an open version and with lip seals on both sides (suffix PP). The end face seals have two seal lips; the outer lip prevents the ingress of contamination, the inner lip retains the lubricant in the bearing.

Features and Benefits

• Lower operating costs

• Reduced maintenance due to improved lubrication

• Lower heat generation

• Less noise

Product Application Information

Due to the closed design, these linear bearings are suitable for use on shafts.
