Rod Seals

The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues.
Ailate offers a wide range of hydraulic rod seals for both single-acting and double-acting systems. These include a unique profiled NBR energised polyurethane (PU) seal, and a specifically designed three element seal for the mining industry comprising of an O-ring energiser, PU shell and a polyacetal anti-extrusion ring.

BSJ

Produced with a combination of special compound PTFE ring and 70 shore NBR O-ring, our BSJ design has a wide application area. Being able to be usded safely at high linear velocity, BSJ type seals can also work in higher temperatures or different liquids by means of changing O-ring used as pressure ring.
By the help of its profile design they can be used as header pressure ring in hydaulic systems without having the problem of hydro- dynamic pressure.
