Deep groove ball bearings, angular contact ball bearings, cylindrical roller bearingssealed ball bearing

Rotation accuracy with the desired rotation precision bearings type size and running accu racy of the bearing by GB bearing type standardized machine tool spindle, gas turbine and control machine requires high rotational accuracy, high speed and low friction, this time should be Use 5 Accuracy more bearings.

Generally use the following bearings:
Deep groove ball bearings, contact ball bearings, cylindrical roller bearings

Just the performance required to meet the mechanical shafting rigid bearing type bearings to withstand load, the contact part of the rolling element and raceway will produce elastic deformation. "High rigidity" refers to the amount of deformation of this elastic deformation is smaller] in the machine tool spindle and the final-stage reduction gear device of the automobile and other parts, to improve the rigidity of the shaft at the same time, must also improve the rigidity of the bearing.

Roller bearings under load deformation of the students is smaller than the ball bearings.ball roller bearing

Preload (negative clearance) can increase the rigidity of the bearing. The method is suitable for the angular contact ball bearings and tapered roller bearings.

The relative inclination of the inner ring and the outer ring of the analysis so that the bearing inner ring and the outer ring to generate the relative tilt of the factors (such as the load caused by shaft deflection, the accuracy of the shaft and housing, bad or mounting error) and able to adapt to such a use condition bearing type. If the relative inclination of the inner ring and the outer ring is too large, the bearing will generate internal load damage. Should choose the type of bearing can withstand this tilt.

In general, allows the tilt angle (or aligning angle) is incremented in the following order:
Cylindrical roller bearings, tapered roller bearings, deep groove ball bearings (angular contact ball bearings) ( ball) bearings, spherical roller

Installation and removal of periodic inspection of the assembly and disassembly of the frequency and frequent assembly and disassembly method of assembly and disassembly, use separable inner and outer rings of cylindrical roller bearings, needle roller bearings and tapered roller bearings is more convenient.

-Aligning ball bearings and tapered bore Spherical roller bearings sleeve through the use of fasteners or refund can be easy to dismantle.
