Metal Face Seals Product Overview
Product Overview
Pioneer Weston’s range of metal face seals offer bearing protection and lubricant retention on any relatively slow-moving rotary shaft. These seals are constructed from two identical, tapered metal rings, loaded using elastomer seals.
Such designs excel under extreme environments, where the exclusion of contaminants such as sand, rock, mud and water is imperative, providing a robust, efficient solution with long service life and low maintenance.
Advantages & Benefits
- Corrosion and abrasion resistant seal rings
- Special seals and load ring materials to match application requirements
- Self-centring to compensate for shaft eccentricity or misalignment
- Cost savings from extended machinery life
- Easy to assemble and minimal maintenance
- Broad operational temperature range from -40ºc to 200ºC, dependent upon material selections
Pioneer Weston can provide a comprehensive range of sizes that are common in the market place. Non standard sizes areavailable on request.

5000 Series
|
- Two identical tapered metal rings with precision lapped opposing faces (One rotating and the other stationary).
|
- The most common design of a metal face seal, available in a large range of sizes.
- O-rings are used as secondary sealing elements providing: static sealing on housing and ID, uniform axial pressure on metal rings, transmits torque to the rotating face.
- Tapered surfaces allow lubrication to get to precision-lapped metal faces via centrifugal action
|
- Large rigid axles, Rock drill bits
- Conveyor equipment (e.g. rollers)
- Planetary gear box (speed reducer)
- Idler rollers for tracked vehicles
- Tunnelling and mining equipment

5500 Series |
- Two identical tapered metal rings with precision lapped opposing faces (One rotating and the other stationary)
- Special elastomer washers
|
- Allows for simpler housing design and construction
- Housing is easier to machine, but more housing space is required
- Tapered surfaces allow lubrication to get to precision-lapped metal faces via centrifugal action
- Special elastomer seals allows higher pressure capability, whilst maintaining the same functions as an O-ring.
|
- Specifically used for undercarriage applications for agricultural and construction vehicles, i.e. bulldozers, excavators
