The NSK HM A series tapered roller bearing is a separable bearing that supports radial and axial loads in one direction. Its design with tapered raceways and guided rollers allows linear contact that distributes the load better. It is used in applications with combined forces that require high load capacity, such as gearboxes, wheel axles and industrial equipment. MR Accesorios Industriales will quote it for you on WhatsApp with the exact part number.

The HM A series designation is read in blocks: HM identifies the dimension series, the number that follows — as in HM 89446 A — defines the size and internal geometry, and the suffix A indicates a design variant within that series. To order the correct replacement, provide the complete part number shown on the bearing or in the equipment manual. If you have any doubts, send us a photo or the part number as it appears and we will quote it for you.

These bearings are used in industries in Argentina such as metallurgy, cement, mining and food processing. They appear in gearboxes, conveyor belts, mills, presses and drive shafts. They are also used in road and agricultural equipment that works with heavy loads and shocks. Their ability to withstand combined forces makes them common in applications where power must be transmitted and axial thrusts absorbed at the same time.

To select the bearing, take into account the radial and axial load, the rotation speed and the available space. Installation requires careful alignment and correct adjustment of the axial clearance, which is set with the cones and cups. Lubrication can be grease or oil depending on the application; in dusty or humid environments, additional sealing is advisable. The raceway and rollers must seat properly to avoid premature wear.

If the original bearing is marked with another brand, we can identify the equivalent from the part number and dimensions. Interchangeability between manufacturers is based on dimension series and suffixes, but they are not always identical: the contact angle, heat treatment or internal clearance may vary. Therefore, before replacing, it is advisable to verify the complete designation and the operating conditions.

To request a quote for your NSK HM A series bearing, write to us on WhatsApp with the complete part number — for example, HM 89446 A — or with the measurements and a photo of the part. At MR Accesorios Industriales we will quote it for you and indicate the compatible alternative if needed. We can also advise you on installation and lubrication so the bearing performs as it should.
