Performance in service

A TDO assembly carries radial load, takes thrust in both directions, and fixes the shaft’s axial position in one envelope. That makes it the standard choice for a short, stiff shaft where there is no room for two widely spaced bearings, and for positions that must resist overturning moments, since the two rows are spaced far enough apart to give real moment stiffness. The spacer establishes the assembly’s internal end play, and its width is ground to suit these particular cones and cup.

Mounting data

Mounting Arrangement: Double cup normally clamped in the housing.

Application types

Application Types: Short stiff shafts with no room for spaced bearings; positions resisting overturning moments; gearbox output shafts; wheel and pinion positions.
