Nxk 12z Needle Roller Bearing

NXK12Z Needle Roller BearingProductDescription
Combination of needle roller bearings and radial bearings and thrust bearings or angular contact ball bearing components of the combination of bearing units, compact structure, small size, high rotation accuracy, can withstand high radial load at the same time to withstand a certain axial load The And product structure in various forms, wide adaptability, easy to install.
Structure type
This type of bearing has a radial needle and thrust full of ball, or with a thrust ball, or with a thrust cylindrical roller, or with the angular contact ball into one, can withstand unidirectional or two-way axial load. Can also be designed according to the user's specific structural requirements.
Materials
Needle roller material for the GCr15 bearing steel, hardened HRC60-65.
Inside and outside the ring material for the GCr15 bearing steel, hardened HRC61-65.
The cage material is made of high quality mild steel or reinforced nylon.
Application
It is dely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other machinery and equipment, and mechanical design can be more compact and smart.
