B 541 SS - 1 stainless steel, Angular Contact Headset Bearing

B 541 SS - 1 Stainless Steel, Torque-Tube Radial Design Headset bearing (1-1/16 x 1-1/2 x 9/32 inch) Radial bearing for internal Headsets featuring 440C stainless steel balls and races to provide maximum corrosion resistance. Torque Tube bearings feature inner races that are slightly wider than the outer race. Not all stainless steel is created equal.Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and as slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless ste
