Shaft seal rings
Suitable for: trucks, trailers and buses
A recent innovation are radial shaft seal rings with a sealing lip made of special PTFE material. Due to the material and the moulding, PTFE sealing lips have a pre-determined pressure and require no additional annular springs.
Due to its structure, the PTFE material has an extremely high resistance to chemicals. The sealing lip is self-lubricating and can also be used at extreme temperatures up to +300°C.
For the assembly, a mounting ring made of cardboard or plastic is usually supplied, so that the PTFE mounting lip is not deformed during installation. Unlike other materials, PTFE must in no case be greased; otherwise tightness is no longer ensured.
