Relubrication with Grease
Relubrication with grease can be carried out from either side via funnel type lubrication nipples in the hexagonal sockets.
A central lubrication adapter is available as a special accessory for connecting the track roller to a central lubrication system.
It is inserted into the bore of the stud in place of the funnel type lubrication nipple.
The hexagonal sockets on both sides of the stud allow quicker and easier fitting. There is no need for special tools or "potentially hazardous improvisations".
