No grease needed in a space environment! Bearings with self-lubricating PTFE liners.

Bearings (bearings)/bushings with PTFE liners designed for use in liquid nitrogen environments (-195°C), requiring no lubrication, and featuring low friction and low wear performance!

RBC's Transport Dynamics developed its own maintenance-free liner products in 1957 and has been involved in the development of self-lubricating liners for aerospace applications. In a space environment, selecting grease becomes difficult due to a wide range of temperatures and evaporation under vacuum. In particular, RBC has developed a special self-lubricating PTFE liner that can withstand environments exposed to liquid nitrogen (-195°C), which is used in space applications. 【Key Points for Choosing This Product!】 - Temperature Resistance: -195°C to +232°C (suitable for special environments such as space and engines) - Low Coefficient of Friction (μ 0.045 to 0.1) - Maintenance-free and clean product that does not require grease/lubricants - Chemical resistance to common aviation hydraulic fluids and other substances 【Product Description】 - Primarily bonded to the sliding surfaces of bearings/bushings (Examples) Spherical/rod end bearings, rod assemblies, etc. - A non-lubricated liner made of PTFE (polytetrafluoroethylene) fibers woven with resin and auxiliary fibers that provide strength and durability, featuring low friction performance.

basic information

We are engaged in product development that meets diverse needs, such as extreme temperature environments in space and aircraft engines, high loads specific to aircraft, and low-cost liners specialized for general industrial applications. 【Product Examples】 - Low temperature environment -196℃: Space products / Fibriloid CR - High temperature environment +316℃: Aircraft engines / Fabroid X - Oscillating motion 11m/min: Helicopters / Fibriloid - Dynamic load 207MPa: Aircraft / Fiberglide V - Dynamic load 207MPa & +232℃: Missile steering components / Fabroid IIG2 - Adhesion is possible with most metals (adhesives are custom products selected by RBC)

Applications/Examples of results

In addition, our company imports and sells bearings and machined parts specialized for aerospace. Manufacturers with AS9100 certification collaborate with major aircraft manufacturers such as the U.S. military, NASA, Boeing, and Lockheed. Below are some examples of our successes: - Fuse pins (achieving emergency breakage in the design of hollow large pins with required load and high-precision breakage mode) - HVOF coating (coating actuator sliding surfaces for increased lifespan; an alternative technology to hard chrome plating) - Track roller bearings for aircraft wings (manufacturers also possess rare testing equipment capable of QT) - Special alloy bearings and bushings (titanium, CuNiSn, Inconel) - Drum-type roller bearings (ensuring grease spreads uniformly around the circumference even under oscillation of wing components for long lifespan) - Ultra-thin ball bearings (adopting thin types for large flap drive devices) - Tapered roller bearings (standardly used for landing wheels)
