Possible cause
Dynamic overload, high impact pressure, fatigue fracture
What to do
- Check chain dimensioning
- Choose more powerful chain
- Reduce load
- Attenuate chain drive

Our FAQs will give you a short description of common problems that might occur when using industrial chains. You will find information on possible causes, pictures of damaged chains to facilitate fast fault detection as well as practical tips on how to solve these problems.
Dynamic overload, high impact pressure, fatigue fracture
Hydrogen embrittlement
Significant overload, overload breakage, result of fatigue fracture at another place, excessive chain wear far beyond replacement level
Dynamic overload, high impact load, fatigue fractures
Excessive chain and sprocket wear, no fixed shafts, insufficient chain tensioning, spring-loaded chain tensioning, not enough teeth
Strong polygon effect, eigenfrequency in the return strand, not enough teeth on sprockets, worn chain and / or sprockets, strands too long
High temperatures, chain overload by starting effects
External impacts
Remove external impacts, plan chain protection box
Strong joint wear due to insufficient lubrication and / or too high joint press, stiff chain, skew
Skew, insufficient alignment of sprockets (angle or parallel misalignment), twisted chain
Dynamic overload, high impact pressure, fatigue fractures, incorrect mounting of spring
Corrosion attack (laminar corrosion, stress crack corrosion, crevice corrosion, pitting corrosion)
External influences, too much lubrication
Chain pitch does not match sprocket pitch, combination of worn chain with new sprockets, chain pre-tensioning too high
Angle and parallel displacement of sprockets, insufficient lubrication, clogging of joint or spaces between plates, soiling, twisted chains
High friction in joint due to insufficient lubrication and / or too much joint pressure, chain tension too high
Different chain lengths, uneven load, uneven lubrication, different drives
Excessive joint wear due to insufficient elongation and / or too much joint pressure, chain tension too high
Rollers overloaded, chain slants, chains and sprockets are worn, bad guide rails
Roller overload, stuck rollers
