Tips: How to choose needle roller bearings?

1. Consider the accuracy of the bearing, through the accuracy of the runout of the rotating shaft, speed, torque change, determine the accuracy level of the bearing, mainly the theory should be related to the actual, spindle accuracy is the most critical, under the premise of high accuracy of the spindle, generally speaking, the higher the accuracy, the faster the speed, the less noise, and the higher the cost.
2. Consider the internal clearance of the bearing, through the shaft, bearing box material and shape, the inner and outer ring offset, temperature difference, bearing fit, preload amount, clear bearing clearance.
3. Consider the cage, through the speed, runout, impact, sound, lubrication, clear cage type and material.
4. Consider lubrication, through the use of temperature, sealing method, rotational speed, lubrication, use environment, clear lubrication and lubricant, and determine the sealing method of the bearing.
