What is Frelon gold?

Frelon is a polytetrafluoroethylene (PTFE) based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating.

What is a self lubricating material?

Self-lubricating bearings work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (graphite, MoS2, lead) based on the requirements of the application (such as operating temperature).

Why is bronze self lubricating?

Oil impregnated bronze: Bronze bearings are very porous and have lightweight oil soaked into the material. Under the optimum conditions, this oil is drawn to the bearing surface creating a lubricated layer between the bearing and the shaft.

Which type of bearing is self lubricated?

A self-lubricating sintered bearing is a metallic component with high porosity (20-25% in volume), impregnated in a lubricant oil. The oil contained in the porosity provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant.

What is a Frelon in English?

noun. hornet [noun] a kind of large wasp.

Is cast iron self lubricating?

Cast iron is assessed as a self-lubricating metal-base composite material. It was found that the friction and wear behaviour of cast iron are influenced by the formation of a graphite surface layer.

What metals are self-lubricating?

Bronze, nickel, iron, iron/nickel and lead can be produced with the lubricants graphite or graphite and molybdenum.

What is the most important quality of oil film lubrication?

Considered the most important property of a lubricant, viscosity serves to form a lubricating film, cool machine components, and seal and control oil consumption. It has to be balanced for load, temperature and speed.

What is a permanently lubricated bearing?

Permanent lubrication is an oil-saturated polymer material molded into the interior of the bearing, filling all internal space without impeding the rolling elements. Micro-pores as small as one ten-thousandth of an inch within the polymer release oil while in use and reabsorb it when the bearing is at rest.

Do all bearings need grease?

Bearings need grease for one reason only, to reduce friction. As long as the lubricant is performing that service well, there should be no need to change it, or add more. Monitor, measure and trend friction levels with ultrasound to know when it is the right time to grease.

Is grey cast iron self-lubricating?

Cast iron is assessed as a self-lubricating metal-base composite material. The formation of cast iron graphite films and the effective surface treatment of grey cast iron are discussed. The coefficient of friction increases with applied load and sliding velocity, and therefore lubrication becomes more important.

What kind of material is the Frelon material?

Frelon (material) Frelon is a polytetrafluoroethylene (PTFE) based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating.

Where is the factory of Mygale in France?

Mygale also produces the chassis used by in Formula Renault, Formula BMW, Formula Three and Formula Four. The company was established in 1989 by Bertrand Decoster and its factory is based in the Technopole of Magny-Cours, France .

What kind of racing car does Mygale make?

Mygale Racing Car Constructor (Mygale SARL) is a French racing car manufacturer that specialises in the production of single seater chassis for use in formula racing. It is most notable for its Formula Ford chassis. Mygale also produces the chassis used by in Formula Renault, Formula BMW, Formula Three and Formula Four.

What makes Frelon a self lubricating bearing surface?

Frelon creates a self-lubricating bearing surface by transferring some of the soft PTFE to the shafting during the running in process.
