Sealed Trolley Wheel Greasers

OPCO® OP-201 Sealed Trolley Greaser

conveyor lubrication equipment icon

The OPCO® OP-201 trolley wheel greaser automatically greases the bearings inside of sealed power trolley wheels while the conveyor is running under normal conditions. The OP-201 operates pneumatically to accurately deliver metered shots of grease into sealed trolley wheels of overhead monorail conveyors.  Specifically, this greaser works by injecting grease into each hydraulic fitting during a lubrication cycle. In addition, a timer, or a counter, can control the duration of the cycle.

Benefits of using the Automatic Sealed Wheel Greaser: 

  • Reduces downtime and manual labor operations
  • Extends the life of conveyor components
  • Eliminates surging caused by non-lubricated and worn wheels
    • Allows closer spacing of product, which in turn increases productivity
  • Conveyor runs smoother, keeps product from swaying
    • Reduces possibility of injury on the line
  • Helps reduce drive power requirements
  • Reduces wasted grease by cleanly and precisely injecting a metered amount into wheels
  • Fitted for overhead or inverted conveyor types
