Miniature rod ends have a joint ball and a housing made of stainless steel. The bearing shells are made of bronze.
The radial clearance is maximum 0,02 mm. The bearing shell is made of PTFE fabric foil in the GKRT version and has an extremely positive effect on the maintenance.
The joints are only oiled at the factory. Rod ends with interanl threads can be lubricated with grease in the threaded hole.
