Fuchs Lubritech PBC is a golden coloured compound formed by a combination of high performance lubricating solids, high molecular weight polymers and soft non-ferrous metallic powders. It does not include soaps, silicone’s or metallic lead.
PBC® is suitable for use as a non-melt extreme pressure lubricant between slow moving surfaces and as a grease at temperatures up to 150°C. Above these temperatures and at temperatures up to 1200°C PBC® forms oxide compounds that are effective as parting agents.
- is a torque equalisation compound and anti-seize, for pre-stressed bolts, studs and threaded components. The co-efficient of friction is typicallyc0.1 @ 20°C.
- Independent testing is recommended.
Plain Bearings, Pivots Trips & Slow Mating Surfaces
- Moving is a protective grease that acts as a lubricating seal to prevent the ingress of water and corrosive solutions. It may also be used as a jointing compound on the joint faces of covers and gaskets.
- PBC® is an anti-fretting medium where relative movement between plain bearing surfaces is of a low magnitude. Examples of such conditions are found on:
Plain Bearings & Splined
- internal surfaces of cement kiln live rings · braking mechanisms · bearing sleeves/rings and housings · splined shafts and serrations · geared / toothed couplings.
Shafts (Vibration & high temperatures):
- Reference – Typical Summary of SRV Test.
- PBC® acts as an anti-fretting medium in rolling element bearings subjected to vibration and small oscillating movements. Such bearings are found in variable pitch blade fans, universal joints / cardan shafts, and the “king-pin” thrust bearings of heavy vehicles. The bearing housings must be completely filled with PBC
Roller Bearings (oscillating):
- PBC® is designed for use as a protective high temperature non-drip/non-melt lubricant for re-greasable conveyor trolley wheel bearings and chain rollers with re-greasable rolling bearings. It can be safely used in conveyor bearings operating over “phosphating” plants and has no deleterious effect on either hot or low temperature acid phosphate solutions. Reference – Typical Data.
