TNA bearings are non-adjustable, double-row bearings that are supplied with built-in clearance. This results in a specified mounting setting range satisfactory for specific applications.
They are similar to type TDO, but the inner-ring front faces are extended so that they abut, which eliminates the need for the inner-ring spacer of a TDO bearing.
They can be used at either fixed positions or allowed to float in the housing bore to compensate for shaft expansion.
Applications: gearboxes, hoisting equipment, rolling mills and machines in the mining industry, e.g. tunnelling machines.
