Ball - 52100 steel - heat treated - protective coated for corrosion resistance.
Race - 52100 steel - heat treated - single fracture - protective coated for corrosion resistance - PTFE lined.
Note 1: GE15ET-2RS - GE120ET-2RS are single fracture race bearings, GE140XT-2RS and GE160XT-2RS are double fracture race bearings.
Note 2: The dimensions and tolerances apply before surface treatment and splitting of the outer race. The outer race becomes slightly out of round due to splitting. When the bearing is mounted into a housing, the roundness of the outer race will be retored. The measured value of the bearing outside diameter without mounting is not to be used as the original actual value of the outside diameter.
