REXROTH R066802000 Linear Bushing Ø20 with Seals

Applications

The REXROTH R066802000 linear bushing (Linear-Set) is designed for precise linear motion guidance on Ø20 mm shafts. It ensures smooth, stable, and controlled movement in industrial automation systems, production machinery, assembly lines, robotics, and conveyor modules. Ideal where repeatability, durability, and reliability of linear travel are required.

Advantages

This linear bushing is manufactured from a high-performance polymer with a low friction coefficient, reducing wear on the shaft and extending system service life. Integrated sealing rings prevent dust, debris, and contaminants from entering the bearing surface, ensuring reliable operation even in harsh industrial environments. The friction-bearing design operates without rolling elements, eliminating the need for lubrication and lowering maintenance costs.

Main Description

The REXROTH R066802000 Ø20 linear bushing is a key component in linear motion systems where high precision, mechanical stability, and long service life are required. Designed as a polymer-based friction bearing, it provides smooth and controlled shaft movement without reliance on rolling elements. This design minimizes maintenance needs, reduces noise, and ensures reliable performance over extended operating periods.

The integrated sealing rings play a critical role in protecting the sliding surfaces against dust, moisture, and small particles. This makes the bushing particularly suited for manufacturing environments, automated systems, CNC equipment, conveyors, and robotic axes operating under continuous duty conditions. Its reduced-friction structure improves overall efficiency while preventing premature wear of both the bushing and the shaft.

The R066802000 linear bushing can be easily mounted in standard linear housings and bearing blocks, providing excellent compatibility within modular linear guidance assemblies. Its reliability and versatility make it a preferred solution for machine builders, maintenance engineers, and industrial automation integrators.
