ORS Bearings Production Process |
 |
Hot Forging By induction heating to 1200 centigrade, bar stock is fed to a high speed, fully automatic Hot Forging Press with loads from 100 to 300 tons, depending on the material diameter. This forms 1 to 2 pieces per second. Forged rings are then subjected to spherodizing annealing heat treatment to achieve a homogenous microstructure and hardness necessary for chip removal. |
 |
Cold Roll Forming Rings that have been forged and heat treated, are then enlarged by Cold Roll Forming. This operation, expands the ring homogenously in all sections. A benefit of this process is the improvement of the rings mechanical properties. |
 |
Turning CNC turning centers or automated lines of single spindle machines are set for continuous processing. |
 |
Heat Treatment Rings are heat treated in specifically designed and controlled atmospheric furnaces, ensuring material oriented for a long service life. |
 |
Grinding Dimensional working accuracy of bearing rings is achieved by grinding and super-finishing of the face, outer diameter, bore diameter and raceways. Tolerances are measured in microns. Super-finishing allows 10 times tighter tolerances as it removes micro-roughness on raceways. |
 |
Washing All components are thoroughly cleaned in fully automatic, ultrasonic units equipped with ultra-filtration service. |
 |
Pressing Cages and shields produced from deep drawn steel strip in fully automatic presses with multiple stations. Roto-finishing removes all burrs. |
 |
Assembly Bearing parts are assembled in fully automatic lines with 100% control of many parameters. After matching of inner and outer races, the balls are inserted, cage is located and riveted, grease is filled, and shields or seals are installed. 100% sound testing of each unit and the final inspection checks are completed prior to the final stage, the application of conservation oil. |
 |
Packing The last step of production is packing to customer requirements. Different options would include single, production, or specialty packaging so that the bearing reaches the customer in the most advantageous manner. |
