TIMKEN Bearing EE450600D - 451212

TDI bearings have a one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. The bearing can be used at fixed positions on rotation shaft applications. For rotating housing application it can be used to float on the stationary shaft.

Product description of TIMKEN Bearing EE450600D - 451212

TIMKEN Bearing EE450600D - 451212,Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. Timken® tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions.Double- or two-row Timken® tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications. And related type you may also like TIMKEN Bearing EE450600D - 451250.

TDI bearings have a one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. The bearing can be used at fixed positions on rotation shaft applications. For rotating housing application it can be used to float on the stationary shaft.

TDI bearings are sometimes used on rotating shaft applications where a loose fit is required for ease of removal.

Size range:
ID 25.400 mm to 1200.150 mm (1.000 in. to 47.2500 in.)
OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504 in.)

Design Attributes:
Double cone and two single cups, with or without a cup spacer.
Furnished as a matched assembly.
Cups ground to fit.

Applications:
Gear reduction units
Cranes
Calendar rolls
Industrial machinery

TIMKEN Bearing EE450600D - 451212,Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. A tapered roller bearing includes a retainer formed with a plurality of trapezoidal pockets. Each pocket includes cutouts formed in the crossbars defining each pocket near the narrow end thereof. A tapered roller is received in each pocket with its small-diameter end facing the narrow end of the pocket. Lubricating oil flowing into the bearing space defined radially inwardly of the retainer can quickly flows through the cutouts into the bearing space defined radially outwardly of the retainer at the narrow end of each pocket. Thus, it is possible to reduce the amount of lubricating oil flowing along the raceway of the inner ring to the large-diameter flange, and thus reduce the amount of lubricating oil remaining in the bearing, thereby reducing the torque loss due to rotational resistance of the bearing resulting from lubricating oil remaining in the bearing.
