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
