High Quality Std Seals /

High Quality Std Seals /High Quality Std Seals /

STD seals: a combination of rubber O-ring and polytetrafluoroethylene ring. O-ring force, grid to circle for the double acting piston seal. Low friction, no crawling, small start force, high pressure. The lattice ring is usually composed of a synthetic rubbery ○-shaped seal and a polytetrafluoroethylene-filled square seal, which can be divided into holes for the ring and the ring, but the seal The role is the same, according to its own deformation on the sealing surface to produce a higher initial contact stress, to prevent leakage of non-pressure liquid. When the hydraulic cylinder is operated, the pressure liquid is extruded through the square seal through the elastic deformation of the ○ -shaped seal to close the sealing surface to produce a higher additional contact stress with increased pressure of the pressurized liquid and Together with the initial contact stress together to prevent leakage of the pressure liquid.

A rod, shaft, and swivel, used for rotation or swinging. It is a two-way pressure or by the role of pressure acting two-way rotating ring. It consists of a combination of a dynamic seal ring and a static O-ring. Seal ring The outer ring seal is specially designed to accommodate high pressure and low speed conditions. One or two annular grooves on the sealing surface can increase the specific pressure of the sealing surface, thus also improving the sealing effect, the groove forming the lubricating oil Cavity, but also reduces the friction, which has a good operational.


 Technical data: working pressure: 30PMa, working temperature: -30 ºC ~ +120 ºC (O-ring material for the Dingqing rubber 70), - 20 ºC ~ +205 ºC (O-ring material for the fluorine rubber 80), the peripheral speed : To 5m / s, working medium: mineral oil hydraulic oil and flame retardant hydraulic oil. Material: Seal ring ------ Polytetrafluoroethylene / carbon compound D32, O-ring ----- Dingqing rubber 70 or fluorine rubber.
