Installation of Needle Roller Bearings

What is needle roller bearing
Needle roller bearings are roller bearings with cylindrical rollers, which are thin and long relative to its diameter. Although there are small parts, bearings still have a higher load capacity, needle roller bearings are equipped with thin and long rollers, so the radial structure is compact, the size of the inner diameter and load capacity is the same as other types of bearings, the outer diameter is the smallest, especially suitable for radial installation size is limited support structure.

The characteristics of needle roller bearing
Needle roller bearings are equipped with slender rollers, so the radial structure is compact, the inner diameter and carrying capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial mounting size of limited supporting results.
According to different occasions, you can use without the inner ring of the bearing or needle roller and cage components, at this time should be suitable for the surface of the shaft and shell holes on the surface of the bearing as the inner and outer rolling bearing surface directly, in order to ensure that the bearing capacity and operating performance is the same as the ring, the axis or shell hole in the raceway surface hardness, the machining accuracy and surface quality should be same as the ring bearing raceway.

Installation of needle roller bearings
Needle roller bearings without inner ring or outer ring:
1. During installation, the rolling surface of the shaft or shell hole can be coated with a thin layer of grease first, and the needle can be attached to the grease of the installation part in turn.
2. When placing the last needle roller, there should be a gap, and the size of the gap should be 0.5mm on the circumference of the needle roller bearing.
3, can not put the last needle roller hard squeeze into, or less than one needle roller, because hard squeeze, the bearing will be stuck and can not rotate;
4. When the load is less, the clearance is too large, which is easy to cause the twisting and breaking of the needle roller when the bearing is running.
Stamped outer ring needle roller bearing installation method:
1. Because the outer ring wall is very thin, needle roller bearings should not be installed by hammering, but should be pressed in by a press.
2. Because the pressure is not uniform when the hand hammer is beating, it is easy to cause local deformation of the outer ring of the needle roller bearing.
