SB-HIEX bearing, bronze,  PEEK and PTFE lined, marginally lubricated bearings 

PEEK / PTFE + Bronze Powder + Steel Backing + Copper / Ting-plating

Features
1. SB-HIEX bearing provides maintenance-free operation;
2. Operate satisfactorily without lubrication under light duty and low speed;
3. SB-HIEX bearing has a high PV capability under high temperature, from to -150℃ to +250℃;
4. Good chemical resistance;
5. High static and dynamic capacity.
6. No water absorption;
7. Suitable for rotating, oscillationg, reciprocating and sliding movement.

Structures

1. PEEK + PTFE 0.30~0.50mm, gives high wear resistance and low friction even only minute quantities of lubricant are supplied. This bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Bronze layer 0.20~0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE/PEEK mixture.
3. Steel backing, provides mechanical strength and high loadcarrying capacity.
4. Copper/Tin plating 0.002mm, provides good corrosion resistance.

Typical Applications  

SB-HIEX bearings application covered gear pump, ABS system, piston pump, gear motor, machine tools, agricultural machinery and so on.
The materials is recommended with initial pre-lubrication at assembly.
