Any bearings are specially manufactured so arbitrarily arranged side by side installation, certain internal clearance or preload and/or uniform distribution of load, but without the use of shims or similar devices. Any bearings with a designation suffix and internal clearance (CA, CB, CC) or preload (GA, GB, GC).
When you place an order to note bearing the number required, rather than a set number.
Single row loading capacity is not sufficient, using pair installed (tandem arrangement); or load is combined or axial loads in both directions when using pair installed (back-to-back and face-to-face).
Line configuration load lines parallel, radial and axial load bearing evenly shared. However, the bearings only accommodate axial loads acting in one direction. If axial loads act in the opposite direction, or if there are combined, it is necessary to add a third bearing of series adjust the bearing pair.
Back-to-back, separated from the load lines of bearings to the bearing axis. Can bear axial loads acting in both directions, but loads only one bearing in each direction. Back to back installation of bearings provide stiff bearing arrangements relatively high, and can withstand the overturning moment.
