Nexus Face Seal is an alternative to Mechanical Face Seals that provides extended service life. It offers a light and flexible barrier against external dirt and mud compression in slow-rotating applications, such as the excavators it was originally developed for. It can also improve longevity and total cost of ownership of gear boxes, undercarriages and axles in nearly any construction or mining machinery.

Key Benefits

Video
  • With its innovative cold stamp process and new material technology it is more cost-effective than comparative products at high volumes
  • High sealing performance at low peripheral speeds, such as encountered in construction machinery and tunnelling, boring and mining operations
  • Good flexibility against mud compression for longer-lasting performance on construction and excavation sites
  • Consistent quality with shortened lead times from stable and efficient manufacturing process

Mud Compression

In heavily contaminated environments, mud can compress between the housing and seal, creating pressure that reduces efficiency and leads to failure.

Nexus Face Seal has a higher flexibility to manage the effects of mud compression, extending service life, particularly for vehicles operating in aggressive and viscous muds encountered on construction sites.

Contamination of Oil

 When an axial seal fails, lubricating fluids become contaminated. This causes excess wear to sensitive components and reduces machine lifespan.

 

After 600 hours of testing in mud, at rotational speeds of 1 m/s, systems using comparative products showed soot and water contamination, characteristics of seal failure. Nexus Face Seal continued to protect the system and deliver long-life performance.
