The NSK TAC C series is a line of angular contact thrust ball bearings built for axial loading in machine tool ball screws. Their design supports high speeds and axial rigidity, which helps maintain positioning accuracy. MR Industrial Accessories supplies this series to customers in the United States and Latin America, and can help you confirm the right part number for your setup.

Reading a TAC C part number is straightforward. The first digits give the bore in millimeters, the letters TAC denote the angular contact thrust type, and the number after TAC is the outer diameter. For instance, 15TAC47C has a 15 mm bore and a 47 mm outer diameter, while 40TAC90C has a 40 mm bore and a 90 mm outer diameter. The trailing C stands for a design variant within the series.

You will find these bearings in the ball screws of machining centers, CNC lathes, grinding machines, and boring machines, where axial forces are the main load. They handle axial forces in both directions, so they suit applications that require repeated positioning.

When selecting a bearing, consider the axial load, the speed, and the rigidity you need. Installation calls for careful alignment and the right lubrication, typically a high-speed grease. The bearing may be open or shielded, depending on the working conditions. Follow the manufacturer's guidance on axial clearance and preload, because those settings affect both precision and service life.

Bearings from other brands can serve as equivalents if the primary dimensions and load ratings align. Still, check tolerances and internal design, as these can differ between manufacturers. MR Industrial Accessories can help you find a compatible alternative for your application.
