The problem, in the infrequent cases where it occurs, is slow precession/ rotation of the outer race within the housing bore. It wears thru the cast iron housing and degenerates into a premature machine failure. I'm aware that the floating / fixed system is designed to relieve axial loads between the bearings. We have tried the o-ring thing for a customer who had this problem. It did not stop ...

Its numerical value can be calculated by subtracting from the diameter of the outer race roller path or ball groove I.D. two times the rolling element diameter and the O.D. size of the inner race roller path or ball groove. On small cylindrical roller and ball bearings, it can be easily measured with a dial indicator gage by laying the bearing on one side, fixing one race, and pushing the ...

Bearing housings support your bearings, protect them from contaminants while keeping in lubricant, and can also house monitoring equipment. Essentially, they provide customizable mounted bearing solutions and help maximize performance, service life and cost-efficient maintenance of the incorporated bearing.

If the outer race is cocked in the housing, the phase readings will depend on how it is cocked (i.e. which point on the bearing is furthest from the machine face, and which is closest). By moving the accelerometer around (safely), the analyst would find a 180° phase difference between those two points. (Figure 4) Fluting or EDM. If current flows between the inner race and outer race, through ...

The race also yields slightly where each ball presses against it. Thus, the contact between ball and race is of finite size and has finite pressure. The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different speeds as it rolls. Thus, there are opposing forces and sliding motions at each ball/race contact. Overall, these cause bearing drag.

Line to Line to slightly loose shaft and housing fits are desirable for most applications. Interference fits may be necessary to prevent one bearing ring from turning relative to its mating part under heavy loads or when cycle vibration is present. An interference fit causes a 50-80% loss in radial play. The contact angle of a radial bearing under axial load is related to the radial play ...

Internal clearance or radial play is the amount of looseness between the balls and raceways of a bearing. For the actual clearances used in the radial play groups, please see our RADIAL PLAY TABLES. Radial play is the clearance measured perpendicular to the bearing axis or more specifically: average outer ring raceway diameter minus average inner ring raceway diameter minus (2 x ball diameter).
