• lubrication recommendations
need to be reviewed; see manu-
facturer’s specifications
• lubrication schedule needs to be
reviewed; see manufacturer’s
specifications
3. Bearing failures -
idlers / hot moist
products
• bearing failures - idlers • outboard bearing mounts to elim-
inate moisture migration through
the bearing interior causing these
failures
4. Belt damage. • head pulley slippage
damaged the belt
• motion sensor must be installed
on the tail pulley or a non-drive
pulley to detect a belt slow-down
• motion sensor must be opera-
tional to shut down the conveyor
immediately
5. Belt failures. • belt is failing prema-
turely
• belt tensions are important to
normal belt life - check for proper
tensions
• hot and oily materials will attack
the belt covers - contact Hi Roller
engineering
• material is too abrasive for the
belt specifications
• material is too hot for the belt
specifications
6. Belt wear -
excessive.
• belt is wearing out on
