Features and Application of Needle bearing:

Needle roller bearings have a high load carrying capacity in addition to their low corss-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited. Because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.

Fitting tolerance When installing the needle bearing, usually the strict fitting is applied, so that its thin-walled outer ring can be supported well. A larger interference will be applied if there is a big load, especially for there is a percussive load. In addition, the temperature difference should notice between bearing outer ring and its connecting parts. Product Precision Accuracy: Dimensional tolerance and geometrical accuracy is based on GB/T5801. Mutual difference of needle roller diameter is 2μm, and the precision grade is G2 (ISO GB309). The diameter of inscribed circle conforms to tolerance grade F6 before the fitting of outer ring with cage and roller assembly. Bearing radial running clearance conforms to the value defined by 0 group of GB/T4604. Special precision grade is based on GB/T307.1 For fuller information on the special requirements of bearing running clearance, inscribed circle and precision grade, please contact this company. Materials: Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65. Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65. Material for cages is quality low-carbon steel or reinforced nylon. Special Directions: Bearing running clearance and inner-cutting roundness should be regulated according to different conditions. Machine tools should be used for press-in fitting or thermal fitting of the bearing.  Limited by plastic cages (suffixed with TN) and sealing-element material, operating temperature is -300C--+1000C. For general -disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.
