Race-Tec Sealing, high performance PTFE lined rotary screw compressor seals differ from many of the available stiff lip PTFE wafer seals on the market, in that during the manufacturing process the PTFE lip section is formed, chemically bonded, and moulded into the elastomer substrate. This substrate provides a flexible and reactive backing to the PTFE lip material.
The use of non-linear Finite Element Analysis (FEA) during the design of the seal lip section ensures that the seals run the minimum required radial lip force, reducing friction, heat generation, and oil carbonisation. This results in reduced wear to both the seal and shaft, a lengthening of service intervals and potential savings in energy and replacement parts.
Race-Tec has a range of standard size rotary screw compressor seals, plus we have the ability to produce small batches of "tailor made" seals for specialist machines or prototype development.
