Perfect bearing sealing

The combination of felt ring and extremely high quality face seals perfectly protect the 2-row angular contact ball bearing races. So, with one oil fill as lifelong lubrication, grease nipples are avoided. Thus, the maintenance time of the compact disc harrow element is substantially reduced. Face seals have been used in the construction industry for decades for sealing rollers and the running gear of track-laying vehicles and they are proven to work reliably under the hardest of operational conditions.
