according to working conditions.
The JRDI rotary seal consists of 4 parts,an elastic element held by L-rings on which the sealing thrust ring lies. The L-rings on both sides protect the entire seal against movement in the seal groove.
Minimal installation space
High pressure allowed
No crawling at start-up, no stickiness
High abrasion resistance
Good dimensional stability
With lubrication chamber
The JRDI sealing profile is specifically designed to accommodate high pressures and low speeds. The back of the seal ring is designed to have a concave curved shape that increases the contact surface and prevents the seal ring from rotating with the rod or shaft. The sealing set should be installed without lubrication.Lubrication should only be used on the sliding surface of the slide ring. It can be used as a sealing element for rotating machine parts,for example in construction machinery and automotive equipment.
