INA Bearing selection should take into account the price of INA Bearing, or use INA Bearing with higher load capacity but more expensive, or use ordinary for long-life ina bearings 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 for long-life 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.
In order to choose the proper size of for long-life ina bearings, the working load, rotating speed and operating temperature of INA Bearing must be accurately calculated or verified.
Load has a great impact on the service life of INA Bearing, so although it is difficult to measure the load, it should also be measured as accurately as possible. When it is difficult to measure the load, the actual power consumed by the motor can be measured, and the power loss along the drive path can be calculated and deducted until the ina bearing load that is closer to the actual load is calculated.
If the calculated or measured load is too large, the expected fatigue life of INA Bearing will inevitably be reduced by a larger margin, which must be remedied. If the installation position allows, the I for long-life ina bearings with a larger size can be selected; If the radial dimension is limited, a wider ina bearing should be selected when there is a wider ina bearing; If the wider INA Bearing cannot be used, the INA Bearing with higher load carrying capacity can be used.
