Bearings arrangements for industrial fans have to meet stringent requirements in most cases. Thereby the bearing units are operating at the limits of physical possibilities - reliable, with low maintenance and high durability. The bearing housing series SNOE from SNR is designed for proper operation, under harsh operating conditions. The SNOE housings are equipped with a spherical roller bearing, which is supplied with lubricant through an oil sump lubrication system during operation. The oil distribution is done by a ring oiler. It transports oil from the oil sump to the upper half of the bearing while rotation. A non-contact labyrinth sealing system ensures an efficient sealing effect, between shaft and housing.
