The NSK TAC series angular contact thrust ball bearing is a precision component designed to withstand axial loads in demanding applications. It is used mainly in ball screws of machine tools, where axial rigidity and rotational accuracy are decisive for machining quality. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on selecting the correct size for your equipment.

The TAC series designation is interpreted as follows: the letters TAC identify the family of angular contact thrust ball bearings, and the number that follows indicates the shaft diameter in millimeters. For example, TAC120-3M corresponds to a bearing for a 120 mm shaft, TAC140-3M for 140 mm and TAC160-3M for 160 mm. The -3M suffix refers to a design variant within the series, which may include specific cage, preload or tolerance characteristics depending on the manufacturer. To confirm the exact interpretation of each code, ask us with the model you need.

These bearings are used in ball screws of machining centers, CNC lathes, grinding machines and boring machines, where they must absorb high axial forces with minimal deformation. They also appear in precision rotary tables and measuring equipment. In the Argentine market, you will find them in metalworking shops, auto parts factories and production plants that require dimensional repeatability. The TAC series is a common solution when high axial capacity and rigidity are sought in a compact space.

To select the correct bearing, take into account the shaft diameter, the working axial load, the rotational speed and the type of lubrication. Mounting requires extreme cleanliness, precise alignment and adequate preload to prevent premature wear. Sealing or protections depend on the environment: in environments with chips or coolant, additional barriers should be evaluated. Lubrication can be grease or oil, depending on the thermal regime. Always follow the machine manufacturer's instructions and verify axial clearance before start-up.

Regarding equivalences, angular contact thrust ball bearings from different brands can be interchanged if the main dimensions, load capacity and tolerances match. It is not enough for the code to be similar: the complete designation and technical specifications must be compared. If you have the code from another brand or an unidentified part, send us the data and at MR Accesorios Industriales we will indicate the compatible alternative or quote the exact size you need.

If you already know the model you are looking for, send us the code on WhatsApp and we will quote it for you promptly. We can also advise you if you need help identifying the part from the housing or spindle dimensions. We work with leading brands and have more than 80 years of experience in the field, supporting Argentine industry with reliable technical solutions.
