Trelleborg Sealing Solutions manufacture and supply PTFE Rotary Shaft Seals for applications where elastomer seals cannot provide a satisfactory sealing solution.

Through the development of both a standard range of seals and an ever increasing demand for bespoke custom designs, TSS have accumulated over 35 years experience in designing and specifying PTFE shaft seals for use in a wide range of applications in compressors, pumps, gearboxes, mixers, machine tools, blowers, bearings, hubs, crankshafts, separators and a variety of specialist equipment.

The properties of the PTFE grades used allow a wide operating temperature range of -100°Cto+260°C whilst providing superb chemical resistance.

Seals can be produced to accommodate pressures up to 2 MPa and with specific designs surface speeds in excess of 90 m/s can be successfully sealed.

Particular benefits can be achieved through the integration of a custom seal into the surrounding system hardware and designs can be produced which are optimized to the specific sealing requirements of the application, such as endurance, power consumption or heat generation.
