Large-scale spherical roller NSK bearing multi-purpose hydraulic device; check the reduction of radial clearance; carry out the device. Use the feeler to measure the clearance; measure the two rows of play together; to be a flat value.
The scale of the bearing increases; when the device is on the shaft; the elliptical deformation occurs due to the outer ring of the self-weight; if the clearance is measured at the lowermost part of the deformed bearing; the measured number will be larger than the practice clearance; the radial clearance with this fault; The interference will be too large; or the device clearance of the practice is too small. Therefore, half of the sum of the two lateral clearances a, b and the lowermost clearance c in the horizontal direction is used as the clearance. When tightening the device to the shaft; ensure that the outer ring can be sensitive and aligning; the clearance behind the device should not be too small.
