The C3 refers to greater radial clearance to allow for high speed environments where excess heat is generated. Generally C3 bearings are used in engine and gearbox environments. You should always replace a C3 bearing with another C3 bearing, and on the same basis avoid fitting a C3 when not called for. C3 Bearings feel loose in normal ambient temperatures prior to fitting, and will show axial play until running at operating temperature.

Challenge bearings offer reassurance of a premium brand and are produced to a high quality standard. In the unlikely event that we should not have Challenge stock available then a quality brand will be supplied.
