Idler/Driver Roller Application conditions: A combine has several different bearing positions, each with similar conditions but having unique challenges;
Two bearings support the roll which spans the width of the bale chamber
Rolls can either be chain-driven or non-chain-driven with driven rolls typically using larger bearings
Support bearings placed outside the chamber are exposed to medium contamination
Support bearings placed inside the chamber are exposed to high contamination
Loading at the end of a baling cycle combined with shaft deflection can generate severe stress on the internal components of the support bearings
Benefits and functional features:
Bolt-on performance:
Several mounting and housing options available
Increased productivity and bearing life in field:
Application specific internal construction accommodates shaft deflection
High contamination feature package with exclusive sealing system
Seal Type: P, TRL
