128720A 176*100*400mm Tungsten Carbide Radial Bearing
The 128720A bearing is a Thrust bearing stacks with an inner diameter of 100 mm , an outer diameter of 176 mm, a width of 400 mm. It typically uses P6 P0 grade precision tolerances and features a GCr15 cage, GCr15 balls, GCr15 rings. It primarily bears Axial, Its dynamic radial rated load is approximately 1300, its static radial rated load is approximately 2000. It uses C0 standard radial clearance, no seals type, GCr15. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Feature: balls
Application: Downhole Drill Motors
