THE FEATURES THAT MAKE THE EF800 HJLTAtSE OPTIMISED MASSIVE BRASS CAGE: PROVEN RELIABILITY The high radial accelerations of vibrating applications place a particular stress on the cage. The EF800 series is equipped with a cage able to respond to this. • Symmetrical rollers with a machined brass alloy one-piece cage centered on the rolling elements. • No floating guide ring or fixed central shoulder section. This prevents any risk of cage/ring seizure in the event of thermal expansion. The self-lubricating properties of the cage material reduce heat buildup at high speeds. • The contoured...
