Damaged or badly fitted slide rail

Inspect and replace as necessary

Conveyor chain is too tight/loose

Tension conveyor chain correctly

Dirty conveyor

Clean conveyor chain and slide rail. Lubricate 
with silicone based lubricant.

Noise

Worn or damaged bearings in drive unit

Check/replace drive unit

Damaged/badly fitted slide rail

Check that chain is free running, especially at 
slide rail joints

Excessive conveyor speed

Lower speed. Check actual load against 
recommended loading.

Incorrect conveyor chain tension

Tension conveyor chain correctly

Motor  
overheating  
on drive unit

Overloaded conveyor

Remove products from conveyor and 
test. Check actual conveyor load against 
recommended loading.

Gearbox leaking oil

Check output shaft seal and area around 
motor/gearbox interface

Dirty conveyor

Clean the chain and slide rail

Abnormal  
wear on  
plastic parts

Overloaded conveyor

Remove products from conveyor and test. 
Check that chain is free running. Check actual 
conveyor load against recommended loading.

Ambient temperature too high

Check recommended temperature for 
conveyor

Chemicals in the environment are affecting plastic 
parts

Check Flextrac Series catalogue (section TR) for 
listing of incompatible chemicals

Damage due to contamination

Clean the system

Particles, swarf etc.

Remove source of contamination
