We provide a wide range of knowledge and there are many factors involved to ensure a completely successful repair of a white metal bearing. These include:

  • A strict quality control process - ISO9001:2015 accreditation, and meeting relevant engineering standards is usual practice giving a security in quality you can rely on
  • An extensive knowledge of bearing metallurgical casting techniques
  • An extensive knowledge and practical experience of bearing failure modes and prevention
  • An extensive knowledge of oil film lubrication (hydrodynamic effects)

Because our customers expect a refurbished bearing to meet the same exacting standards of a new bearing, the same rigorous techniques and controls are used in refurbishment work as those used in new manufacture.

Bearing failure is serious. Downtime is expensive and speed of response is critical, so when the worst happens you need the services of a company with a proven track record in speed of response and total reliability.
