A Guide For Purchasing High Roller Slewing Bearings

17/9/2021· A large diameter lagging roller bearing, also known as a jib, enables the user to work on a wide variety of projects because it is able to run at a lower than average acceleration speed. Because of their low speed performance, the cost of these parts is significantly lower than those for a single-row roller bearing design.
