The configuration of the TDO provides a wide effective bearing spread, making it ideal for applications in which overturning moments are a significant load component. TDO bearings can be used in fixed positions or allowed to float in the housing bore.
Applications: gearboxes, hoisting equipment, rolling mills and machines in the mining industry, e.g. tunnelling machines.
