J101 Linear Plain Bearings Polymer Self lubricating Plastic Flanged bushing
J101 flanged plastic bushing is type of self-lubricating bushing.It's specifically to offer a balance of low friction, high wear resistance, and high load capacity. These bushings are designed to operate without external lubrication, making them maintenance-free and a cost-effective alternative to metal or bronze bearings.
Material:
Dark Grey Plastic
Feature:
Self-Lubricating:It contains solid lubricants embedded within the material, eliminating the need for external lubrication and preventing contamination
High load capacity:It can handle significant loads, making them suitable for various applications, including those with edge loads or vibrations.
Wear-resistant: It is designed to withstand wear, even in demanding applications involving high loads and continuous movement, with negligible wear.
Chemical resistance:It exhibits resistance to various chemicals, including some acids, greases, and oils.
Easy installation: It is designed for press-fit installation into a housing bore.
Cost-effective: They offer a cost-effective solution compared to metal or bronze bearings, especially when considering maintenance and lubrication costs.
Environmentally friendly: They require no lubrication, contributing to a cleaner environment by avoiding the release of contaminants.
Application
- Pneumatic rotary drives
- Steam pipelines
- Automotive engine compartments
- Conveyor chains
- Pneumatic cylinders
- Control levers and pedals in vehicles
