Thin-wall linear ball bearings are compact recirculating ball bushings designed for low-friction travel on hardened round shafts where radial space is limited. PBC Linear KHP Series bearings use a slim, heat-treated alloy steel shell with a polymer resin retainer that guides the recirculating balls and helps reduce operating noise. Available exclusively in a closed ISO metric configuration, the KHP design conserves space and weight while providing rolling-element motion for compact housings and assemblies. ID sizes include 6, 8, 10, 12, 14, 16, 20, 25, 30, 40, and 50 mm, with load ratings reaching 5,500 N (1,200 lb) dynamic and 6,300 N (1,400 lb) static on the KHP50. Use with Simplicity 60 Plus™ carbon steel or compatible hardened 440 stainless steel shafting; KHP bearings are not intended for 316 stainless steel or ceramic-coated aluminum shafts. Applications include compact automation, packaging machinery, medical and laboratory equipment, and light industrial motion systems.

Frequently Asked Questions
What is a thin-wall linear ball bearing?
A thin-wall linear ball bearing is a compact recirculating ball bushing with a reduced outer diameter compared with a standard linear ball bearing. The thinner profile conserves radial space while providing low-friction travel on a hardened round shaft.
When should I use a thin-wall linear ball bearing?
A thin-wall design is useful when a machine needs low-friction recirculating ball motion but has limited radial space around the shaft. Typical applications include compact automation, packaging, medical, laboratory, and light industrial equipment.
Are KHP bearings available in open or adjustable versions?
No. The PBC Linear KHP Series consists of closed ISO metric bushings and does not include open or adjustable configurations.
What shaft should I use with a KHP ball bushing?
KHP ball bushings should run on hardened round shafting designed for rolling-element contact, such as Simplicity 60 Plus™ carbon steel or compatible hardened 440 stainless steel shafting. They are not intended for unhardened 316 stainless steel or ceramic-coated aluminum shafts.
What is the difference between a linear ball bearing and a linear ball bushing?
The terms are commonly used for the same type of component: a cylindrical bearing with recirculating balls that travels along a round shaft. Ball bushing emphasizes its cylindrical form, while linear ball bearing describes its function.
