The TDO (Two-Row Double-Outer Race) by Timken, has a configuration which helps achieve a broad effective bearing speed, and hence makes it suitable for use in applications which consider overturning moments as an important load component. The TDO bearings can be put to use in floating position in the housing bore or in fixed position too. Available in size ranges from 25.400 mm to 1200.150 mm for ID and 30.480 mm to 2460.000 mm for OD, the TDO bearings have a design comprising of double and two single cones, with or without spacer. When the spacers are used, the bearing is furnished as a preset and matched assembly. These spacers are available with or without lubricant grooves and holes. Thus the TDO bearings can be used in Heavy-Duty gear drives and various other industrial configurations.
