How are pulley diameters and shaft diameters selected?
Pulley diameters and shaft diameters should be selected using tools such as ANSI/CEMA B105.1-2003 (SEE APPENDIX A). The following application variables need to be considered in the selection of both the pulley outer diameter and the shaft diameter: Excessive shaft deflection occurring as a result of an undersized shaft (exaggerated for effect).
What are the dimensions and running accuracy of rolling bearings?
■Bearing accuracy Accuracies of rolling bearings, that is, dimensional accuracy and running accuracy of rolling bearings are defined by applicable ISO standards and JIS B 1514 standard (Rolling bearings – Tolerances) (Tables 2.4 and 2.5).
Can a large shaft cause a conveyor pulley to fail?
Premature failure of a conveyor pulley is not likely to occur from an oversized shaft, but an undersized shaft can produce harmful and destructive results.
How big does a loose ball bearing need to be?
Loose ball bearings come in huge variety of sizes. Loose ball-bearing sizes are determined by the diameter of the ball bearing itself. This is usually expressed as a fraction of an inch: 3/16in (4.7625 mm). The exact size of bearing required will differ between individual components.

How big of a pulley do I need for bulk handling?
In bulk handling applications, an adequate pulley face length is one that is 2” or 3” greater overall or 1” to 1.5” greater on each end than the overall width of the conveyor belt. Unit handling applications may warrant deviation from these guidelines.
