Pulley wear criteria

Pulley wear criteria

Pulley wear criteria

Is there any written criteria for identifying when a pulley is too worn?  All the literature I have found addresses worn belts but never a worn pulley. Other than "if it slips, throw it out" as a criteria, I would like to somehow come up with a tangible measuring method for establishing a re-use criteria for a worn pulley. Thanks, I hope someone can help!


RE: Pulley wear criteria

Apart from your stated "if it slips, throw it out", when the inside face of the belt is close to contact with the pulley its time to replace.

RE: Pulley wear criteria

Belt manufacturers (such as Gates) can give you a series of inexpensive plastic templates which quickly let you determine whether excessive wear is present. I have seen them for all of the standard sizes and belt profiles.
