Sheathed carbon brush for dry low pressure - ambient conditions |
摘要 |
The external surfaces of the brush, with the exception of the running surface, are coated with a film of fluorocarbon polymer. This is applied as a molten waxy film with a thickness of between 0.005 and 0.05 mm. and prevents drying out of the brush with consequent increase in wear rate. |
