The NSK TTF series tapered roller bearing is a compact unit that combines two rows of tapered rollers in a single assembly, with integrated sealing and lifetime lubrication. It is designed to withstand combined radial and axial loads in both directions, with high rigidity. It is used in wheel hubs, axle hubs and automotive and industrial applications where space is limited and simple, reliable installation is required.

The TTF series designation is read in blocks: the numeric prefix identifies the size and execution, followed by the letters TTF that define the family of sealed tapered rollers. The final suffix, as in the example *203TTF4153A, provides variants of sealing, tolerance or internal design. To correctly interpret each part number, it is essential to respect the exact order and characters published by NSK.

In Argentina, these bearings are used in wheel hubs of light and heavy vehicles, hubs of agricultural machinery, earthmoving equipment and industrial transmissions. They also appear in pumps, gearboxes and lifting systems where combined loads must be supported with low friction and minimal maintenance.

To select the right TTF, take into account the radial and axial load, the operating speed and the environmental conditions. The integrated sealing protects against contaminants and retains lubrication, so it does not require periodic greasing. During installation, ensure correct alignment and avoid blows that could damage the sealing lips. Preload and internal clearance are already set at the factory.

NSK TTF series bearings can be interchanged with equivalent units from other brands that share dimensions and load capacity. If the customer brings a part number from another brand or an unidentified part, at MR Accesorios Industriales we will quote it for you and indicate the compatible alternative. Interchangeability must always be verified with the measurements and tolerances of the assembly.
