Product Description

P101 Linear Plain Bearings Overview

P101 flanged plastic bushings are self-lubricating linear plain bearings engineered to deliver optimal performance with low friction, high wear resistance, and substantial load capacity. These maintenance-free bushings operate without external lubrication, providing a cost-effective alternative to traditional metal or bronze bearings.

Material Specifications

Dark Grey Plastic - Engineered polymer composite with embedded solid lubricants for superior performance.

Key Features & Benefits

Self-Lubricating: Embedded solid lubricants eliminate external lubrication requirements and prevent contamination
High Load Capacity: Handles significant loads up to 80 MPa, suitable for applications with edge loads and vibrations
Wear-Resistant: Withstands demanding applications involving high loads and continuous movement with negligible wear
Chemical Resistance: Resistant to various chemicals including acids, greases, and oils
Easy Installation: Designed for press-fit installation into housing bores
Cost-Effective: Economical solution compared to metal bearings with reduced maintenance costs
Environmentally Friendly: No lubrication required, preventing environmental contamination

Industrial Applications

Pneumatic rotary drives and cylinders
Steam pipelines and conveyor chains
Automotive engine compartments
Control levers and pedals in vehicles
Exhaust valves in milling machines
Track rollers in mini excavators
