When a spindle must handle axial forces at high speed while staying rigid and accurate, the NSK TAC series angular contact thrust ball bearing is a common choice. MR supplies this series and can help you match the right part number to your machine tool or other precision application.
The part number tells you the key dimensions and design details. Take 140TAC03DM: the first three digits give a 140 mm bore, TAC identifies the angular contact thrust series, 03 sets the contact angle, and DM points to a special execution, often a matched pair with preload. The same pattern applies to 160TAC03DM and 180TAC03DM, which have 160 mm and 180 mm bores. Reading the code correctly helps you avoid ordering the wrong bearing.
You will find these bearings in milling, boring, grinding and machining center spindles, where axial loads dominate and rotational precision is essential. Rotary tables, drill heads and measuring equipment also use them. In metalworking, automotive and machine tool operations, they support reliable, repeatable production.
Selection depends on the axial load, the top speed and the stiffness the spindle needs. During mounting, use the right tools to protect the raceways and check that the shaft and housing are aligned. Apply the grease or oil specified for the application, and choose sealing based on the working conditions. If preload is required, follow the spindle manufacturer's specification.
Other manufacturers may offer bearings with similar designations, but precision bearings of this type are not universally standardized. When replacing, compare the main dimensions, contact angle and preload conditions. If you have a part number from another brand, MR can identify a compatible alternative and quote the exact bearing you need.

Frequently asked questions
- What does the DM suffix mean on a TAC bearing?
- DM typically indicates a special execution, often a matched mounting pair with a defined preload or a particular treatment. For the exact meaning in your application, contact us with the full part number.
- How do I choose between the different bores in the TAC series?
- The bore must match the spindle shaft. Part numbers such as 140TAC03DM, 160TAC03DM and 180TAC03DM correspond to 140 mm, 160 mm and 180 mm bores. Check the housing dimensions and the required axial load capacity.
- Does this bearing require special mounting?
- Yes, because it is a precision spindle bearing, follow the machine manufacturer's instructions. Controlling alignment, preload and lubrication is critical. If you need assistance, contact us on WhatsApp.
