ROULEMENTS A L'ABRI DU FEU

摘要

Combination of bearing and lubricant for use in smoke and heat exhaust ventilation systems allows the bearing to withstand temperatures of 600[deg]C for 60 minutes with a shutdown of 2 minutes after 15 minutes exposure. The bearing is made from stainless martensitic steel and has a steel cage. It is lubricated with a conventional electric motor lubricant with a base oil viscosity of 50 - 200 cSt at 40[deg]C.
