Problem

Fracture Plate

Overloading

Inspect the drive to determine the cause of high load and eliminate Or Redesign drive for larger pitch chain

Broken Pins

Overloading

Inspect the drive to determine the cause of high load and eliminate or Redesign drive for larger pitch chain

Broken Pins (Centre)

Loading is greater than pin’s dynamic capacity

Inspect the drive to determine the cause of high load and eliminate or Redesign drive for larger pitch chain

Broken Pins
(Offset Pin)

Overloading

Single pitch offset link is to be eliminated Redesign drive using a higher capacity chain

Fatigue Failure

Loading is greater than chain’s dynamic capacity

Single pitch offset link is to be eliminated Redesign drive using a higher capacity chain

Cracking

Stress corrosion cracking

Inspect the drive to determine the cause of high load and eliminate Select anti-corrosive chain

Broken Roller

Speed too high Sprockets too small Chain riding too high on sprocket teeth

Replace chain, reduce speed Use larger sprockets or possibly redesign drive for small sprocket

Worn Contour

Chain rubbing on casing, guide or obstruction

Replace chain if 5% or more height worn out Inspect and redesign casing, guide and eliminate interference

Pin or Bushing Galling

Speed or load too high Inadequate lubrication

Reduce speed or load Redesign drive for smaller pitch chain Provide proper lubrication system
