BRS Bearing – Double Row Tapered Roller Bearings

BRS manufactures double row tapered roller bearings in the TDO and TDI designs. These bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.

TDO – Double Outer Ring

TDO series bearings are composed of a single cup for double outer-race, two cones with roller and cage assemblies, and usually with an intermediate ring(spacer) between the two inner rings. There are holes in the outer ring of TDO bearing, which can permit the use of pins to prevent outer ring rotation in the housing.

TDI – Double Inner Ring

TDI series bearings are composed of two cups, single inner ring for double inner race with roller and cage assemblies.Usually with an intermediate ring(spacer) between the two outer rings.

Application

Double row tapered roller bearings are typically chosen for applications where overturning moments are a significant load component. For example, gearboxes, hoisting equipment, rolling mills and machines in the mining industry, tunneling machines.
