Development means even better piston and
rod seal
A new development of the long established Turcon Stepseal K by Busak+Shamban has resulted in a seal which is claimed capable of out-performing any other seal in its class.
Development of the long established Turcon Stepseal K by Busak+Shamban has resulted in a seal capable of out-performing any other seal in its class The original Turcon Stepseal K, used throughout piston and rod sealing applications, has a sealing mechanism based on hydrodynamics, whereby a micro-thin film of oil is dragged out of the cylinder, under the contact of seal, when the rod is moving out and dragged back when the rod is retracting

The oil serves to lubricate the seal, consequentially reducing friction and wear and maintaining long term sealing efficiency.
New Turcon Stepseal 2K has a refined profile which further optimises the hydrodynamic sealing principle of the original seal.
A new profile provides improved performance at the low pressure side of the outer diameter, enabling the O-Ring to benefit from increased deformation space - critical in high-pressure systems.
The refined seal profile has an improved load distribution.
In practice, reduced friction and improved return flow is experienced.
A further benefit relates to increased extrusion resistance enabling the new seal to be used in piston / rod designs with an allowable radial clearance of +30%, significantly reducing costs in hardware manufacture.
In a tandem sealing installation the interaction of increased return flow and reduced friction results in the secondary seal avoiding high loading.
The overall system can benefit in a frictional reduction of up to 35% with a consequential increase in system life.
The exceptional capabilities of the new Turcon Stepseal 2K make it the ideal sealing solution for a very wide range of cylinder applications, including mobile plant, stationary hydraulics, transmission, aerospace, automotive, chemical and processing and pharmaceutical manufacture etc.
