Low Carbon Steel (Case Hardened)
General Information
Balls of this type are generally used in applications where there are only moderate loads and slow rotating parts, for example Castors, Conveyors and non-precision bearings. There is a significant price saving compared to High Carbon Chrome balls.
The main feature of this type of ball is the Carburised case with a soft core giving resistance to shock loads, good load carrying ability and excellent resistance to surface wear.
