We have CNC machines and cooperate with universities and research institutions and have rubber material research and development team.
We established long-term cooperative relations of technology talents with Qingdao University of Science & Technology, Hebei University of Technology, northwest Rubber Institute, each batch on employee training, improve the staff technical level and cultural structure, creating a number of business elites. It lays a solid foundation for the healthy development of the company.
L-shaped piston seal ring: for reciprocating hydraulic cylinder, cylinder piston seal to prevent dust, dirt invasion of the moving parts
Widely used in reciprocating dynamic sealing device, its life is higher than the O-ring. Y-ring for the working pressure of not more than 40MPa,
the working temperature of -30 ~ 80 C,
Operating speed range: the use nitrile rubber rubber:0. 01 ~ 0.6m / s;
using fluorine rubber: the 0.05 ~ 0.3m / s;
When made of polyurethane rubber, compared with 0.01 ~ lm / s.
L-ring sealing performance, service life and the working pressure of the different ring limit, are better to polyurethane rubber material.
L-ring features:
1) L-shaped (cup) piston dust seal:
Product use: for reciprocating hydraulic cylinder, cylinder piston seal
Material: NBR rubber
Operating temperature; -40 ~ 80 C
Working pressure: 1-32Mpa
Working medium: liquid, gas
Hardness of product; HS70 ± 5A
Standard: HG4-335-66
