INA Bearing selection should take into account the price of INA Bearing during heat treatment, or use INA Bearing with higher load capacity but more expensive, or use ordinary INA Bearing and try to prolong its service life.
Ina bearings with high load capacity are used, such as cylindrical roller ina bearings with convexity, spherical roller ina bearings with symmetrical rollers, reinforced tapered roller ina bearings and ball ina bearings, ball ina bearings with modified ball groove bus, or 70000cd series ina bearings are used to replace deep groove (single row centripetal) ball ina bearings. These ina bearings with high load capacity or due to the improvement of stress distribution, Or there may be higher fatigue life due to the large number of rolling elements.
The price of ina bearing material should also be taken into account. When vacuum smelting or electroslag remelting steel has to be used, it should be noted that the lubrication conditions must be improved in order to double the expected fatigue life of INA Bearing.
Tentu saja, the cost of selecting ina bearings made of this kind of high-quality steel is much higher than that of selecting INA Bearing during heat treatment with high load capacity. Namun, for ina bearings that are difficult to access in machines and are extremely difficult to install and disassemble, or ina bearings used in mining and tunnel operation machinery, it is sometimes necessary to consider using them in situations where maintenance is extremely difficult.
