The induction hardening of conveyor chain sprocket teeth results in only the localised hardening of the tooth surface. This means that FB induction hardened conveyor chain sprockets are only hardened in the working area around the individual tooth profile. To achieve such precision hardening the applicator coil is only exposed to the tooth profile. This precise action results in the sprocket teeth being hard without negatively affecting the bore and other parts which fortunately remain softer and more ductile.
Hard conveyor chain sprocket bores are well known to cause premature wear on shafts and by induction hardening only the teeth of our hardened conveyor chain sprockets FB avoid such difficulties.
FB induction hardening will extend your conveyor chain sprocket life particularly in heavy load drives or severe and abrasive environments.
