The Tractive diff has proved to offer winning performance. This is top class performance at a reasonable price! We produce clutch pack differentials with 3 internally toothed friction discs per side. The diff features floating ramp plates for immediate response without the need for preload. The ramp plates always have two sets of ramps, for example 30/65 or 40/65 degrees for drive and overrun respectively. The internally toothed discs are molybdenum-coated and the external discs are nitrided for increased longevity. The bevel gear dimensions are dimensioned to give long life and smooth operation. For long lifetime on ramps and gears, four planetary gears are used, running on high strength crossed shafts. Empori

Company Products Technical info Technology Sales & Contact News The Tractive concept Manufacturing Assembly Quality control Quality control By manufacturing all specially designed components in-house, we have full control of quality throughout the entire production process. Quality must be produced at the source! The entire production of parts is subjected to a rigorous inspection procedure. All important components, turned or milled, are controlled for accuracy in our 5-axis CNC co-ordinate measuring machine or other highly accurate specialized control equipment. All data is recorded and filed for future reference. All structural parts are numbered directly when they are produced and all manufacturing and inspection data is filed. Complete control of the production process makes for excellent quality management and a high-quality end product. Sheffield 5-axis CNC co-ordinate measuring machine Virtually all parts are subjected to careful inspection in our Sheffield Cordax 5-axis CMM. Records are kept for all critical parts.
