slim ball bearing

N type and NU type axial moving, can adapt to the changes due to thermal expansion and installation error of the shaft and the casing crossed roller bearings‍ relative position, can be used as a free end bearing.

Use. The inner or outer ring can be separated, which is convenient for installation and disassembly. 3.4 the processing requirements of shaft and hole high, slim ball ‍bearing inner and outer ring axis relative deviation after installation must strictly control, so as to avoid the contact stress concentration. Hole with 1:12 taper double row cylindrical roller bearings 3.5, precision spindle bearings‍ radial clearance can be adjusted, radial rigidity is high, suitable for machine tool spindles.

The 3.6 cross roller bearings, cylindrical roller in a V shaped groove 90 degree roll surface through the isolated blocks are arranged vertically, so the cross roller bearings can bear radial load, axial load and torque load and multi direction load. The inner ring and the outer ring size is miniaturized, thin form is small size is close to the limit, and has the advantages of high rigidity, and the precision can reach P5 P4, P2. The rotary table is therefore suitable for industrial robot joint part and a rotating part, reali slim bearings‍ machining centers, precision equipment rotary table, medical equipment, calculators, military industry, IC manufacturing equipment etc..
