The TIMKEN TNA series is a line of radial tapered roller bearings built to handle simultaneous radial and axial forces. You will find them in assemblies where running accuracy and load support matter, including gear reducer boxes, transmission shafts and various industrial machines. MR Industrial Accessories supplies this brand and can help you pin down the exact size your application calls for.

Reading the TNA designation: the letters TNA identify a family of single-row tapered roller bearings. In this series, the part number typically combines those letters with numeric codes for size and suffixes that flag design details such as contact angle or cage style. When you request a quote, the complete part number or the primary dimensions (bore, outer diameter and width) will let us match the right bearing.

In US plants and throughout Latin America, TNA series bearings show up in tough spots: speed reducers, road machinery, mining equipment, mills, presses and conveyors. The agricultural sector also relies on them in seeders and combine harvesters, where combined loads and harsh conditions call for bearings that hold up.

Selecting a bearing from this series involves checking radial and axial load capacity, operating speed and lubrication method. During installation, correct alignment and axial clearance adjustment are essential; clearance is typically set with lock nuts, lock washers or shims. Sealing also matters: pick radial shaft seals or other seals that keep out dust and moisture based on the working environment.

TIMKEN tapered roller bearings can be swapped with equivalents from other well-known brands, including SKF, FAG, NSK or NTN, provided the main dimensions and contact angle line up. Before replacing a bearing, confirm the full part number and tolerances. At MR Industrial Accessories, we can point you to the right equivalent for your equipment.
