Mechanical Equipment [Daily Question] 2012.01.11: Multiple-choice question – For rolling bearings with non-adjustable clearance, what should be used as the basis for assembly? A. Original radial clearance B. Installation clearance C. Operating clearance D. Axial clearance. Answer: A. 100 people participated in this question, and 32 of them got it right. Some people answered B and C. The basis for assembly is to determine, prior to installation, the fit clearance between the bearing and the shaft as well as between the bearing and the hole (installation clearance) based on the bearing’s original clearance and precision, thereby achieving an appropriate operating clearance that ensures the proper functioning of the equipment.
Select the appropriate clearance for imported bearings from Wuxi according to the equipment requirements; http://www.xzt-nsk.com/. Generally, it is better to choose a lower clearance for normal use, as the clearance of the bearings tends to increase slightly over time as they are in use
