PTFE ROTARY LIP SEALS
UltraLip PTFE seal are formed or machined from highly wear resistant PTFE lip seal composites for long life, low friction, high surface speeds, poorly lubricated conditions and soft shafts. Available with metal backing or o-ring on the seal OD for support and to prevent seal rotation. A variety of flexiseal PTFE Seal profiles provide the designer with significant improvement in performance over Omniseal PTFE / Polymer Seal at a much lower cost than mechanical face seals.
Features and Advantages:
- Temperature Range: -20 C to + 250 C
- Pressures up to 30 bar
- Excellent chemical resistance
- Ultra low friction
- Dry running or abrasive media
- Surface speeds up to 25 m/s
- Easy to install and replace
- Metal support for higher temperatures
Type M50: Shaft speed up to 25m/s. Maximum pressure = 5 bar. Used in lubricated and non lubricated applications. Maximum temperature 100ºC.
Type M51: As type M50 but due to the metal support ring can be used up to 200ºC or maximum O-ring material temperature.
Type M52: Improved sealing of gases and abrasive media due to higher lip load. Not recommended for shaft speeds greater than 8m/s.
Type M53: As type M52 but can be used up to 200ºC or maximum O-ring material temperature due to metal support ring.
Type M54: Incorporates spring loading for use in applications where shaft run-out or misalignment exists. Pressures up to 3 bar. Speed up to 7m/s.
Type M55: As type M54 but can be used up to 200ºC or maximum O-ring material temperature due to metal support ring.
Type M56: Shaft speed up to 30m/s. Maximum pressure 1.5 bar. Low friction seal, used as environmental seals.
Type M57: As type M56 but can be used up to 200ºC or maximum O-ring material temperature due to metal support ring.
Type M58: Used in high pressure hydraulic applications - pumps, hydraulic motors. Operational PV factor bar m/s max.
Type M59: As type M58 but the clamping is in the axial direction which requires the gland width to be held to the seal width -0.0/+0.1
