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

The Oiles 500HP series of bearings are made up of robust unique alloy bases with solid lubricant impregnated in them. They have excellent wear resistance even at high bearing pressures.


  • Carries more weight than the 500SP5. Shows greater wear resistance in high-load and low-speed applications.
