ZF 634319132 – Output Shaft Seal Ø50 × Ø70 × 10 mm
The ZF 634319132 Output Shaft Seal is a high-performance sealing element engineered for output shafts in high-pressure mechanical systems. Manufactured from advanced elastomers such as Nitrile Rubber (NBR) or Fluoroelastomer (FKM), it offers outstanding resistance to oils, lubricants, water, and high-pressure fluids. Designed to operate under extreme conditions, this seal delivers reliable performance from –40°C to +200°C and resists pressures up to 15 MPa (2175 psi). With a press-fit installation and optimized lip seal design, it ensures tight, leak-free operation and long-term reliability in marine propulsion systems, gearboxes, and hydraulic applications.
Key Features:
- Material: NBR or FKM for chemical and thermal resistance
- High-pressure capability up to 15 MPa (2175 psi)
- Wide operating temperature: –40°C to +200°C (–40°F to +392°F)
- Seals output shafts in marine, industrial, and automotive systems
- Optimized sealing lip design prevents leaks under rotation
- Excellent resistance to oil, lubricants, water, and pressure fluids
- UV, ozone, and weathering resistant for harsh environments
- Reduces maintenance needs and component wear
- Press-fit design for quick and secure installation
