Maintenance
Ring Gear
Bearing:
Lubrication of the bearing component is provided through the auto-lube system. The automatic lube
station only greases the bearings. For any other component that needs greasing, do a visual
inspection every month and add grease as needed. Operation of the auto-lube is detailed here under.
For machines without the auto-lube system, apply EP2 grease with a grease pump every month, or
as part of your regular maintenance program. Move bearing several times to ensure complete fill.
Or use appropriate grease if you have requested a different type of grease in your system (ex. FDA-
approved) or if your operating environment requires a different type of grease (ex. cold temperature
environment).
Inspect the seals to ensure they are properly inserted into their grooves and that they are intact and
preventing contaminants from entering the bearing
Teeth:
Visually inspect the teeth once a month. Remove buildup if present. With steel pinion, if teeth are
dry, apply grease with a brush all around ring gear. Use high quality open gear grease (Mobile
Unirex EP2 GCLB or equivalent). With nylon pinion, no greasing is necessary. Backlash between
gear and pinion needs to be kept at approximately .005".
Lube Station
The Lincoln greaser is controlled by a PLC output and should be greasing for 60 seconds every 2,400
revolution of the rotation. It can be adjusted on the HMI.
Inspect the grease container of the lube station once a month and refill with EP2 grease as
recommended by Wulftec unless you have requested a different type of grease in your system (ex.
FDA-approved) or if your operating environment requires a different type of grease (ex. cold
temperature environment). The lube station needs to be refilled before it is empty. To fill the
container, use the fitting located on the front side until you reach the max. line.
