Blue POM DX Bushing Metal Polymer Composite Plain Bearing SF-2 Self lubricating Bushes
ZR-020B boundary lubricating POM bushing is a type of DX bearing with blue color POM coating. This type of metal ploymer composite plain bearing has same material structure with other DX bearing. It's also called SF-2 boundary lubricating bearing, three layer oilless bearing,plain sliding bearing and dry bushes.
Material Structure
1. POM with fillers
2. Porous bronze
3. Steel backing
4. Copper plating or tin plating
Characteristics
Low friction, anticorrosion and long life
Suitable for marginally lubricated and dry operating conditions
Performance is similar to DS bushing in foreign country
Availability
Standard cylindrical DX bearing, DX thrust washers and strips are available.
Special designs can be made according to your design
Application
ZR-020B composite plain bearing is widely used in hoisters, bulldogger, tower cranes, and printing or dyeing machines for textiles, steering gear, power steering and so on
