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 machine tool ball screws, 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. 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 rotation speed and the type of lubrication. Mounting requires extreme cleanliness, precise alignment and adequate preload to avoid 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 check axial clearance before start-up.

As for equivalents, angular contact thrust ball bearings from different brands can be interchanged if the main dimensions, load capacity and tolerances match. A similar code is not enough: 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 tell you 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 promptly. We can also advise you if you need help identifying the part from the housing or spindle dimensions. We work with leading brands, supporting Argentine industry with reliable technical solutions.

Frequently Asked Questions

What does the -3M suffix mean in TAC bearings?
The -3M suffix identifies a construction variant within the TAC series, which may involve cage, preload or tolerance characteristics. To know exactly what it means in your model, send us the full code and we will give you the precise information.
How do I choose the right TAC thrust bearing for my spindle?
You need the shaft diameter, axial load, speed and type of lubrication. With that data we can guide you. If you have the original code, send it on WhatsApp and we will quote the exact size you need.
Can I replace a TAC bearing with one from another brand?
Yes, if dimensions, load capacity and tolerances match. Do not rely on the code alone: compare the complete designation. If you send us the competitor's code, we will tell you the compatible alternative or quote the exact part.
