Imperial Double-Row Tapered Roller Bearing
The double-row tapered roller bearing consists of one double-row outer ring and two inner rings each assembled with tapered rollers and cages. A spacer ring is usually installed between the two tapered inner rings of this bearing type. Thus, these bearings are ready-to-mount units, as their axial clearance or preload has already been set during the manufacturing process. The tapered inner rings of such bearings are arranged in a back-to-back configuration, which causes the load lines to diverge toward the bearing axis. Therefore, the bearings are suitable for rigid arrangements and can withstand relatively large tilting moments.
