Stepseal

O.D. Sealing

The sealing performance of the stepseal 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 Stepseal:

• 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

Material: Bronze (T46)

Used as a standard material for hydraulics, it offers high compressive strength, good sliding and wear properties, and good extrusion resistance. Typically a greyish to dark brown color.
