Needle Roller Bearings Curved Roller Bearings KR22 CF22 Mechanical Bearings
Characteristics and uses of needle roller bearings,
1. The needle roller bearing is equipped with thin and long rollers (the length of the roller is 3 to 10 times the diameter, and the diameter is generally not more than 5mm), so the radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings.
2. The diameter is the smallest, especially suitable for the support results with limited radial installation size. According to the different occasions, the bearing or needle roller and cage assembly without inner ring can be selected.
3. At this time, the surface of the journal matching the bearing and the surface of the housing hole are directly used as the inner and outer rolling surfaces of the bearing to ensure the load capacity and running performance.
4. Same as the bearing with ring, the hardness, machining accuracy and surface quality of the surface of the shaft or shell hole raceway should be similar to the raceway of the bearing ring. Such bearings can only bear radial loads.
