Timken bearing repair technology: another cost-effective option for replacing bearings
Improvements in technology, materials, condition detection, reliability maintenance processes, and machining processes make bearing repair technically possible.
Technically, bearing repair is the repair or replacement of damaged parts of the bearing to meet the state requirements of the new bearing. For example, after long-term use of bearings, rolling elements, raceways, pins and other components inevitably have fatigue damage. During the bearing repair process, the bearings are fully repaired by grinding the raceways, replacing rolling elements, pins and other components. . In this way, its functional components or surfaces are fully compliant with the requirements of the new bearings.
2.2 Market feasibility
With the intensification of competition in the industry, various manufacturers have tried their best to reduce equipment maintenance and production costs in order to improve the market competitiveness of products. On the other hand, with the rising prices of raw materials such as steel, the rising price of bearings has become the main reason for the increase in production costs of industrial enterprises.
Compared to the manufacture of new bearings, the high-quality repair process can restore the bearings to the new bearing in 1/3 of the time. Compared with the purchase of new bearings, bearing repair technology can help industrial enterprises to save at least 40% or even higher procurement costs, and under normal use and maintenance, the repaired bearings can fully achieve the performance of new bearings.
In this way, bearing repair has very good market feasibility.
2.3 The need for energy conservation
Bearing repair is more environmentally friendly than new bearing manufacturing, requiring less energy input and reducing raw material consumption and waste. The main energy consumption for new bearing manufacturing includes steel, forging, heat treatment and grinding, all of which can be saved by bearing repair.
In addition to cost and time savings, bearing repair is most likely to achieve a bearing life cycle. Research by authoritative research institutes shows that after repair, the life cycle of the bearing can be the same as the life cycle of the new bearing. The repaired bearing re-uses the proven reliable bearing steel material, thus further reducing the risk of bearing material failure. Replacement parts must be of the same material and tolerances as the original manufacturer or equivalent, and repairs that do not conform to the original manufacturing specifications will increase the risk of premature failure.
