HK071209 Needle Roller Bearing Advantages:

1.Needle roller bearings are equipped with slender and long rollers (the length of the rollers is 3-10 times the diameter and the diameter is generally less than 5 mm), so the radial structure is compact.

2.When the inner diameter size and load capacity of needle roller bearings are the same as other types of bearings, the outer diameter of needle roller bearings is the smallest, which is especially suitable for supporting structures whose radial mounting size is limited.

3.The processing accuracy and surface quality of needle roller bearings should be combined with bearing rings and applications according to their different application situations.

4.Needle roller bearing is a bearing unit composed of centripetal needle roller bearing and thrust bearing components.

HK071209 Needle Roller Bearing Features:

1.Needle roller bearings are equipped with slender and long rollers (roller diameter D < 5mm, L/D < 2.5, L is roller length), so the radial structure is compact.

2.When the inner diameter size and load capacity of needle roller bearings are the same as other types of bearings, the outer diameter of needle roller bearings is the smallest, which is especially suitable for the bearing results with limited radial installation size.

3.According to the different use occasions, the bearing without inner ring or needle roller and cage assembly can be selected. At this time, the journal surface and the outer shell hole surface matched with the bearing directly serve as the inner and outer rolling surface of the bearing.

4.In order to ensure the same load capacity and operation performance as the ring bearing, the hardness of the raceway surface of the shaft or shell hole, and the processing accuracy. And the surface quality should be similar to the raceway of bearing ring. This kind of bearing can only bear radial load

Description:

1.Needle bearing is a roller bearing with cylindrical roller. Compared with its diameter, the roller is slender and long.

2.This kind of roller is called needle roller.

3.Despite its smaller cross section, bearings still have a higher load-bearing capacity.
