An Engineering Guide for Bearing Selection - STLE

Selecting the correct lubrica - STLE

Reducing lubricant selection for a plain bearing down to a few pages of practical guidance is difficult. Plain bearing design includes 20-plus vari-ables, including aspects of the build design and materials (bearing size, shaft radius, clearance, frictional force, friction coefficient, shaft speed, ec-

Lubricant application: Grease volumes and frequencies

for spherical and thrust roller) element bearings is somewhat easier to estimate. Initial fills for very low PLVs can range from 33% to 80%, assuming accurate bearing selection. The initial fill amount can be a higher percentage of the original volume as the PLV declines and vice versa. As with plain bearings, one should consider both feed

Stathis Ioannides and Ted Harris at SKF ran with this idea, confirmed the FAG results, and in 1985, 25 years ago, wrote a pivotal paper titled “A New Fatigue Life Model for Roll-ing Bearings.” Their methodology built on previous work but accounted for current technology and data. Forget about independent life adjustment factors, they said.

5. SELECTION OF BEARING SIZE - NSK

A 24 A 25 By designating the basic rating life as L h (h), bearing speed as n (min–1), fatigue life factor as f h, and speed factor as f n, the relations shown in Table 5.2 are obtained: on which the bearings are to be mounted should also be considered.
