AST850BM Metric Series 25.000 Millimeter (mm) Nominal Shaft Diameter (d) and 28.00 Millimeter (mm) Nominal Bearing Outside Diameter (Do) Metal Backed Bronze Powder and Solid Lubricant Bushing

The AST850BM Series Bushings are metal backed with bronze graphite oil-less bushings and have the following layers:

1. Sinter bronze powder with graphite: good wear resistance with lower friction and excellent load carrying capacity. Can be machined after fitting to get precision tolerance. AST also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing: gives exceptionally high load carrying capacity, excellent heat dissipation.
3. Copper plating 0.002mm, providing good corrosion resistance.
