1.Product Introduction:
NKIA bearing, which is combined needle roller bearing is a bearing unit composed of radial needle roller bearing and angular contact ball bearings. NKIA bearing features compact structure, small size and high rotating accuracy and bearing certain axial load while holding very high radial load. NKIA bearing has multiple structure styles, broad adaptability and easy installation. Furthermore, it can be inlayed with our IR standard ring. It is widely used in machine tool, metallurgical, textile and printing machinery. NKIA bearing can make the design of machine system highly compact and nimble.

3.Pruduct precision accuracy:
Dimensional tolerance and geometrical accuracy is based on JB/T8877.
Mutual differences of needle roller diameter is 2um, and the precision is class G2(ISO GB/T309).
The diameter of inscribed circle comforts to tolerance class F6 before the fitting of outer ring with cage and roller assembly.
Bearing radial running clearance conforms to the value defined by class 0 GB/T4604
Special accuracy grade is based on GB/T307.1
For fuller information on the special requirements of bearing running clearance, inscribed circle and precision, please contact our company.
4. Material:
Material for needle roller is GCr15 bearing steel, quench-hardening HRC60-65
Material for inner and outer rings is GCr15 bearing steel, quench-hardening HRC60-65.
Material for cages is quality low-carbon steel or reinforced nylon.
5. Special Directions:
Axial load of NKIA, NKIB series of bearings is not allowed to exceed radial load by 25%.
Being used for supporting alternative radial load, it must be installed in opposition.
Thrust bearing parts must exert preload up to 1% of axial basic rated static-load.
When plastic cages are used(suffixed with TN), operating temperature is not allowed to surpass +120鈩?during continuous work.
Thrust bearing parts can move freely in bearing bracket.
For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.NKIA Series Bearings sizes
