Conveyor Chain Tension – How to Properly Tension the Chain

Periodically checking the chain tension of your SmartConveyor(s) is normal and recommended. This article will go over the basics of how to adjust the tension and how to determine if it needs to be tightened or loosened

Step 1: Is to assess the chain tension. If the chain can be lifted up and over and flop to the side of the conveyor (see image below) it is too loose and needs to be tightened.

Conversely if it is so tight that it can’t be lifted up off the channel it is too tight.

A properly tensioned chain should be able to be lifted, in the middle of the chain, about 2-3 inches above the track. (see below)

Step 2: To adjust the chain tension you will need (2x) 3/4 inch open wrenches. First loosen the tightening bolt (See image below, #1)

Next loosen the jam nut(s) (see image above #2) and then tighten the one jam nut or the other to tighten or loosen the chain.

After adjusting the chain remember to tighten both jam nuts.
