Preventative Maintenance for Modular Plastic Conveyor
Belts
Modular plastic conveyor belts typically do not require day-to-day maintenance and are
generally trouble-free when installed and operated properly.
Following are a few recommendations to obtain maximum life of the belt and avoid
down-time.
Check belt tension on a routine basis (weekly or monthly) to ensure proper drive.
Adjust screw take-up if necessary. (Belts experience thermal expansion while hot.)
Sprocket alignment should be checked before installing the belt to ensure that all
the teeth are in line. (A misaligned sprocket can cause the belt to break or go off
track.) On round-bore sprockets, it is good practice to check the keyways and
tighten keyway setscrews when required.
If a small section of the belt or a module breaks, it is important to replace it as soon
as possible. Failure to do so could incur further damage to the belt. Try to
determine the cause of the break before restarting to avoid the break from
happening again.
Make sure that when you join the belt, the metal connecting rod is locked in with a
plastic tab.
