10x17x5 G.WB NBR
Product description
The WB version without the NBR dust cover is equipped with a metal housing compared to the WA version. Due to the reinforcement of the outer casing, the bearing is more resistant to harsh conditions and installation errors. This reinforcement is particularly important for larger diameter guffers, The simmering guffer is used to seal the spaces around rotating shafts. The sealing bit, which is compressed by a spring, encircles the shaft and ensures the correct sealing pressure. In this way, two liquid or gaseous environments with a small pressure gradient can be separated.
