Oiles 500SPR-SL1 Hard special copper alloy bearings with embedded solid lubricant

Oiles 500SPR is constructed of a unique copper alloy that is tougher and more impact-resistant than Oiles 500HP. Wear resistance is superior in both high-load and low-velocity operations.

Features

  • Suitable for pressures more than 500HP
  • Can be used in high-load and high-impact situations.
  • Assist in the implementation of a long-term operation or a compact design.
