VORBAL-Glide sliding layer
VORBAL-Glide is the maintenance-free race used on CLASSIC heavy-duty spherical-plain bearings and rod ends. The liner is a polyamide-PTFE-glass compound. It runs dry, traps particles, and is thicker than a typical PTFE fabric — which is why it lasts in food and dusty plant.
Do not wash Glide joints with solvents that attack the sliding layer. Do not grease a Glide race unless the series drawing says so.
