The TIMKEN NA series covers double-row tapered roller bearings built to carry radial and axial forces at the same time, which suits equipment that needs high capacity and a stiff shaft arrangement. Two rows of tapered rollers share the work, so the assembly stays stable under load. These bearings turn up in industrial machinery and power transmission drives where precision matters. MR Industrial Accessories LLC supplies this line and helps buyers confirm the right reference before ordering.

Reading an NA reference starts with the base code. Numbers such as NA357, NA366 or NA385 point to double-row bearings, each with its own design details. The digits after NA define the size and geometry of the assembly, and any suffix tells you about seals, cage style or mounting features. Getting familiar with this coding helps you order the correct replacement and keeps the NA series apart from other tapered roller lines.

Typical duty includes mining, cement, steel, mills, conveyors and farm equipment, plus gearboxes and transmission cases that run under heavy loads at moderate speeds. Because the two rows handle combined forces, these bearings work where alignment is not perfect and small misalignments have to be absorbed. MR Industrial Accessories LLC serves plants and workshops across the United States and in several Latin American countries.

Selection comes down to the radial and axial load the position sees, the rotation speed and the surrounding conditions. Sealing deserves attention: in dusty or damp areas, pick a configuration with seals that keep the lubricant in place. Use the lubricant type the manufacturer recommends and renew it on the maintenance schedule. At mounting, verify that the housings are aligned and set the correct axial clearance so the bearing is not overloaded. Careful installation pays off in service life.

On interchangeability, double-row tapered roller bearings can cross between brands when the main dimensions and tolerances line up. Not every code swaps directly, though, since contact angle, sealing or cage differences can change how the bearing performs. Validate any substitution with a specialist first. Our team can point you to a compatible alternative or confirm the reference you already have.
