PBC is suitable for use as a non-melt extreme pressure lubricant between slow moving surfaces and as a grease at temperatures up to 150Â°C. Above these temperatures and at temperatures up to 1200Â°C PBC forms oxide compounds that are effective as parting agents.
Threaded Fastenings: PBCÂ® is a torque equalisation compound and anti-seize, for pre-stressed bolts, studs and threaded components. The co-efficient of friction is typically 0.1 @ 20Â°C. Independent testing is recommended.
Plain Bearings, Pivots, Trips & Slow Moving Mating Surface :PBCÂ® 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. Mating Surfaces:PBCÂ® 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 Shafts (Vibration & high temperatures) :
- internal surfaces of cement kiln live rings
- braking mechanisms
- bearing sleeves/rings and housings
- splined shafts and serrations
- geared / toothed couplings.
- Reference â€“ Typical Summary of SRV Test.
Roller Bearings (oscillating) : PBCÂ® 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 â€œking-pinâ€ thrust bearings of heavy vehicles. The bearing housings must be completely filled with PBC
Roller Bearings (rotating) : PBCÂ® 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 â€œphosphatingâ€ plants and has no deleterious effect on either hot or low temperature acid phosphate solutions. Reference â€“ Typical Data.
