NBI Taper Roller Bearing (TRB)

*Paired single row taper roller bearings

Paired taper roller bearings are used where either the load capacity of single bearings does not meet the requirements, or to overcome the time consuming adjustment under the conditions of a mass mounting.

Paired taper roller bearings consist of two matched single row taper roller bearings using spacers for a specific axial clearance or a preload.

* Depending on the particular requirements, such pairs may be supplied in:

Tandem arrangement, DT suffix

Bearings in tandem arrangements are used where the actual thrust force exceeds the load capacity of a single bearing. Require two spacers for matching as a unit, hence the desired total width of the bearing arrangement must be defined when ordering.

Back to back arrangement, DB suffix

Thrust forces are accommodated in both directions and in each direction forces are supported by one of matched the tapered roller bearings. Require two spacers for matching as a unit, the desired total width of bearing arrangement must be defined when ordering.

Face to face arrangement, DF suffix

Thrust forces are accommodated in both directions and in each direction forces are supported by one of the matched tapered roller bearings. For bearing pairs arranged face to face the heating of the shaft will cause either a reduction of axial internal clearance or an increase in preloading forces.

Other arrangements are produced upon order request.
