In forged steel castor, balls roll over the untempered racings of the castor head. Due to friction, the racings get worn out causing the balls to fall down and the only solution is to replace the castor. On the Other hand, these castors have bearings. Since the surface of the bearings is hardened it gives longer life to this castor.
