NTN-SNR® bearings with the specially-developed Rust Guard™ phosphate coating have a significantly enhanced resistance to corrosion. This makes them a reliable choice for applications in wet environments such as the wire and press sections of paper machines. NTN bearings. SNR bearings.


  • The Rust Guard™ coating has been specially-formulated to prevent the premature failure of bearings due to rust.
  • Bearings with the Rust Guard™
    coating enjoy improved reliability and a replacement cycle extended by between 1.5x and 2x when compared to conventional bearings.
  • Good anti-seizure properties due to the grease retention capacity of the Rust Guard™ coating.
  • Coating available for all types of bearings including spherical roller bearings and tapered roller bearings.
  • Coating suitable for all types of materials such as bearing steels and case-hardened steels.
  • The RustGuard™ coating can also be applied to the NTN® EA series of bearings, offering a dramatically expanded service life under severe operating conditions.
