Punched Needle Roller Bearing (GCr15 bearing steel)

Punched Needle Roller Bearing

Needle Roller Bearing 
needle roller bearing is a bearing unit composed of machined outer ring & inner ring, cage and needle roller assembly featuring small section height, big load capacity & rigidity, compact structure and small size, high rotating accuracy with the structure of disposed inner ring.
needle roller bearing is characterized by multiple structures, broad adaptability and easy installation.
It is widely used in auto, lathe, metallurgical, textile, printing industry & other various machinery equipment. With this kind of bearing, machine design can realize the goal of small-scale & lightweight.
Types of Designs:
This kind of bearing has multiple structural styles for the choice of customers, such as narrow & broad series, with or without inner races, cages, ribs or sealings. It can be designed according to the special structural requirements of customers as well.
Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T5801.
Mutual difference of needle roller diameter is 2μ M, 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.
