Self-Lubricating Bearings Solutions


High Performance, Low Wear Solutions

A self-lubricating bearing is a metallic component permeated in a lubricant oil. The oil provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. Kaman Specialty Bearings features high performance, low wear self-lubricating bearing solutions.

Machinable / Moldable Liners


Noted for its high performance and low wear rate, Kamatics’ self-lubricating liner systems have established superior results in providing longer life and lower maintenance costs, even when operating in areas of high moisture, fluid/debris contamination, and elevated temperatures. Our maintenance free liner systems provide low friction, high load capacity, long life with low rates of wear, and a large temperature range for a variety of applications.

Fabric Liners

Fabric Liners for Bearings

RWG FRASLIP self-lubricating bearing materials are based on specially engineered liner fabrics with a tight woven fabric of synthetic fibers coated / saturated with a unique matrix of PTFE powder, high strength resin, and special fillers. This design provides high load rating, uniform wear behavior, low friction and extended service life.

Dry Film Lubricant


KFL-DM is a unique surface coating liner that provides durable, lubricious, low friction sliding performance. KFL-DM is typically used for applications requiring a thin, low friction coating for metal surfaces that contact one another, and cause surface damage from rubbing and fretting.

Carbon Based Coating


Carbon Based Coating (CBC) was developed to provide a hard mating surface for PTF-fabric self-lubricating bearings. CBC can be used on a titanium ball within a spherical bearing, or for metal to metal bearings to create a superior tribological system with its friction partner. CBC fulfills the requirements of aerospace specifications for such coatings.
