Stepseal
I.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.
