These balls have an intrinsically low carbon content so they're relatively soft and flexible. By case hardening, we're able to increase the rigidity of the external surface to produce a product that's both tough and tensile.
Benefits
Case hardened Low Carbon Steel balls are very cost-effective and the combination of a hard, carburised case and soft core gives them superb resistance to shock loads; the flexible core delivers outstanding load bearing while the hard case shrugs off surface wear.
Use
You'll find them used in castors and conveyors, and anywhere that requires non-precision bearings, from baggage handling and sliding walls to scales and drawer runners.
