Do you really know the assembly requirements for ntn inc of bearings?

186 Published by admin Mar 27,2019

1.Before assembling the ntn inc of bearing, measure the fit size of the ntn inc of bearing. First, do the cleaning according to the rust prevention method of ntn inc of bearing; check if ntn inc of bearing is intact. And no rust, rotation should be flexible and no abnormal sound. These are things to consider before assembling ntn inc of bearings. Contact us for details!

2.When assembling ntn inc of bearings by temperature difference method, the bearing temperature should not be higher than 100 °C; the cooling temperature should not be lower than /80 °C.

3.ntn inc of The bearing outer ring and the bearing housing or the box hole should be in accordance with the provisions of the equipment technical documents. For split bearing housings or open housings, there shall be no clearance for the split joint; the outer ring of the bearing and the bearing shall be in uniform contact with the bearing cap within 90° of the symmetrical centerline and within 90° of the symmetrical centerline. It should be inspected with a 0. 03mm feeler gauge and the length of the plug should be less than 1/3 of the length of the outer ring. There shall be no banding between the outer ring of the bearing and the semicircular holes of the bearing housing or the open box.ntn inc

4.ntn inc of bearing and shoulder or bearing seat shoulder should be tight; tapered roller bearing and radial thrust ball bearing and shoulder clearance should not be greater than 0. 0
5mm, the clearance with other bearings shall not be greater than 0.1 mm. The bearing cap and washer must be flat and should fit evenly over the end face of the bearing. When specified in the equipment technical documentation, clearances may be provided as specified.

5.When the radial clearance of both ends of the assembly shaft is not adjustable, and the axial displacement of the shaft is a radial bearing defined by the two end covers, a clearance should be left. When the technical documentation of the device is not specified, the gap may be taken from 0. 2 to 0. 4 mm.

6.ntn inc of radial bearings, needle bearings, spiral roller bearings should be flexible after assembly. When lubricating grease bearings are used, clean grease of 65% to 80% of the cavity volume should be filled in the bearing cavity after assembly, but grease-lubricated bearings should not be filled with grease.

7.ntn inc of single-row radial ball bearings, radial thrust tapered roller bearings, radial thrust ball bearings mounted on the journal and in the bearing housing axial pre-tightening (axial pre-interference), should be bearing Implementation of standards or equipment technical documents.
