Rod step seals

The sealing performance of the step seal results from the hydrodynamic properties of the seal. The seal edge creates a steep contact pressure gradient on the high pressure side and a shallow contact pressure gradient on the low pressure side. The controlled pressure gradients minimizes fluid adherence and enables residual fluid to be returned into the system. The O-Ring relief chamfer reduces pressure loading on the seal, whereby contact and sealing performance is improved at high service pressures. The special high-lift rear chamfer combines a smooth downstream sealing face with the ability to meet large radial clearances and hardware tolerances.

Advantages of step seal:

High static and dynamic sealing effect

High extrusion resistance, meets high hardware clearances

Low friction, high efficiency

Stick-slip free starting, no sticking

High abrasion resistance, high operational reliability

Wide range of application temperatures and high resistance to chemicals depending on material

Applications:

Injection molding machines

Machine tools

Presses

Mobile hydraulic

Hydraulic hammers
