1. Application and properties

Suitable for reciprocating oil and cylinder under harsh working conditions, mainly used in hydraulic and pneumatic devices, servo systems, chemical and food equipment. Excellent sliding performance, no stick-slip or crawling phenomenon, can compensate for large deformation of piston rod and plunger, very good compatibility with hydraulic media, effectively erase the remaining oil film adhering to the surface of the piston rod from the inside. Can remove stubborn stains, suitable for equipment working in particularly harsh environments such as mines, quarries, and cement plants.

Small groove size.

Operating temperature range from -30°C to +160°C.

Can be used for special working conditions such as extremely high speed, extremely low speed, micro-stroke, etc.

Main features:

Ⅰ. low friction coefficient, can work with or without lubrication;

Ⅱ. strong resistance to media;

Ⅲ. wear-resistant, long service life;

Ⅳ. can be used in harsh working conditions

2. Standard material
