Quality Assurance and Inspection Technology

HB Bearings are at the forefront of inspection technology. During manufacture, bearings are subject to a rigorous inspection program which takes place before final assembly. HB Bearings have two temperature controlled inspection rooms with state-of-the-art computerised (CNC) inspection equipment. This ranges from hardness testing, surface finish, roundness testing, contour inspection and co-ordinate measuring machines. We are in a position to provide precision bearings and be confident of the quality via stringent inspection regimes.
