Apr 11 2014Avoid overloading or use bearings with higher basic static load ratings • Action Select heavier interference fits Improve Lubrication method • An Article on "Bearing Life" and catalogue Published by SNR bearings • "Bearing Failures and its Causes" published by QIBR bearings

A guide to shaft and housing fits for SMB Bearings

The ideal fit is where the shaft/housing is the same size as the bore/O D of the bearing This is known as a line- to- line fit and gives optimum bearing performance Looser fits are commonly used and often preferred for ease of assembly or where spring preloading

Jul 29 2019Bearing life is typically expressed in B10 or B50 and is a value of hours This is simply an estimate on how many operating hours at a given load a bearing will last prior to failure In working with our checkball pumps Dynex Sales and Engineering are constantly reviewing bearing life with applications to evaluate what product will be the best

Bearing number starts with 5 indicates axial deep grove ball bearings or thrust bearings Such bearings are basically designed for heavy axial load or thrust load Bearing number 51200 is an example of axial deep grove ball bearings or thrust bearings

Cylindrical roller bearings carry heavy radial loads and light thrust loads at high speeds They also accommodate fast acceleration Cylindrical roller bearings are the most basic type of roller bearing and use rollers instead of balls as a rolling element These rollers are slightly crowned and have a greater length than width

The more important a bearing is the more carefully it should be inspected The determination to reuse a bearing should be made only after considering the degree of bearing wear the function of the machine the importance of the bearings in the machine operating conditions and

The temperature difference between the bearing and seating depends on the magnitude of the interference fit and the bearing size Normally a bearing temperature of 80 to 90 C (144 to 162 F) above that of the shaft is sufficient for mounting Never heat a bearing to a temperature greater than 125 C (257 F) unless otherwise specified
