Characteristic of IXIN needle roller bearing    
         
Drawn cup needle roller bearings     
Structure:This bearings has open ends and closed ends 2 types, gererally shaft diameter from φ 6~φ 60mm, multi-lips seal available.
Accuracy:Needle mutual tolorence 2μ m, precision grade G2(ISO/GB309), Thin section out ring will be affected by rigid housing.
Material:Needle: GCr15 (100Cr6), Drawing cup and cage can use carbon steel
Instruction:Working temperature: -30— +100.    
         
Needle roller bearings      
Structure:This kind of bearing has multiple structures, such as narrow & wide type, with or without inner races, cages, ribs or seals.
Accuracy:Dimensional tolerance and geometrical accuracy is based on GB/T 5801(ISO. 1206)
 The mutual-difference of needle' s diameter is 2μ m, precision grade G2(ISO/GB309)
 The diameter of inscribed circle conforms to tolerance grade F6 before the fitting of outer ring with cage and roller assembly.
 Clearance conforms to the value defined by 0 group of GB/T4604 (ISO 5753)
 Special precision grade is based on GB/T307 (ISO 492, DIN 620) 
Materials:Material for needle roller is GCr15 (100Cr6) bearing steel, quench-hardness HRC60---65.
 Material for inner and outer rings is GCr15 (100Cr6) bearing steel, quench-hardess HRC61---65.
 Material for cages is low-carbon steel or nylon 66  
Instruction: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.
         
Needle roller and cage assemblies     
Structure:There are single-row K-type and double-row K… ZW-type for this kind of bearings. Special structure of single row K… D-type and double row K… ZW-type can be available according to the special structural requirements of customers.
Accuracy:Mutual difference of needle rollers is 2μ m, and the precision class is G2 (ISO/GB309).
 The assembly nominal width Bc is – 0.20 for upper deviation and  -0.5 for lower deviation.
Materials:Material for needle roller adopt GCr15 (100Cr6) bearing steel. 
 Material for cages can be quality low-carbon steel, low-alloy steel and nylon66.
Instruction:The width of axial location is based on the assembly nominal-width Bc and conforms to the tolerance defined in H12 regulation.
 For plastic cages TN type, operating temperature is less than +120C during continuous work.
         
Axial thrust needle roller and cage assemblies
