   Load bearing is required to carry (the weight which is being exerted through the combined weights of the shaft and any other direct weights on the shaft and measured in pounds-force per square inch): Formula: L = W / (I.D × L.O.B.). Example: Determine the load on a bearing of a 2-inch I.D. bearing, 5 inches long and carrying a weight of 3,100 lbf:

   Sleeve bearings of inch dimensions are almost exclusively dimensioned using the SAE numbering system. The numbering system uses the format -XXYY-ZZ, where XX is the ID in sixteenths of an inch, YY is the OD in sixteenths of an inch, and ZZ is the length in eighths of an inch. [10] Metric sizes also exist. [11]
