UHMWPE Wear Resistant Chain Guide Rails
Xinxing
UHMWPE (Ultra High Molecular Weight Polyethylene) is a very tough material, with the highest impact strength of any thermoplastic presently made.
Why using UHMWPE as the perfect material of chain guide rail?
Very high impact strength
Exceptionally low friction and high abrasion resistance
Low water absorption, almost zero
Excellent chemical and oil resistance
High operating temperature, best character for high speed
Lower cost than steel
Processing Equipment:
CNC cutting machine
CNC planing machine
CNC engraving machine
CNC machine tool
