1. Application and properties

Suitable for rods, shafts, pins, rotating joints, etc. that rotate or pivot with angular motion. It is double-acting rotary sealing ring that can withstand pressure from both sides or alternating pressure. It is used in industrial fields such as construction machinery, manipulators, and automobiles.

Low friction, no viscous phenomenon, smooth start-up, and even at low speeds, there is no crawling.

The groove is simple, and the cross-sectional size is small.

Good wear resistance, stable dimensions and highly compatible with hydraulic media.

High temperatures resistance and good anti-extrusion properties.

It can withstand a certain reciprocating motion while rotating.

2. Standard material

5. Marking method

Mark it with the dimension of installation groove as below：

GNS “Nominal diameter dimension D” × “Groove Diameter d” × “Groove Width L”

For example: GNS100×89×4.2 means Groove dimensions: φ100×φ89×4.2
