Description
NSK 40TAC03D belongs to thrust ball bearing de contacto angular, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 40TAC03D and any equivalents.
The NSK TAC series covers angular contact thrust ball bearings built for axial loads acting in a single direction, combining rigidity with the running accuracy that spindles and rotary tables demand. MR Industrial Accessories LLC supplies this series in a range of sizes to maintenance and purchasing teams throughout the United States and Latin America.
Reading the code is the fastest way to pin down a size. Take 15TAC02D: the leading 15 is the bore in millimeters, TAC marks the series, and the digits that follow set the contact angle and internal geometry. The same logic applies to 40TAC03D, where the bore is 40 mm. The trailing D identifies a particular construction variant within the series, so two bearings with the same bore can still differ in configuration.
Typical installations include milling, grinding and machining center spindles, positioning tables and precision shafts. Metalworking, automotive and capital goods operations rely on them wherever axial motion has to stay accurate. Because the design carries load in one direction only, these bearings suit assemblies set up with preload and stiffness in mind.
Selection starts with three inputs: the axial load, the running speed and the lubrication method. Correct mounting calls for exact alignment and the right preload, since play undermines performance. Grease or oil are both options, and the sealing choice follows the working environment. Adjustment and axial fixing should always follow the manufacturer's instructions.
Equivalent nomenclatures exist from other manufacturers, but they are not automatically interchangeable. When replacing a bearing, compare the critical dimensions and the operating conditions before committing. Our team can review your data and point you to a workable match that keeps equipment performance intact.

Frequently asked questions
- What does the TAC designation mean in these bearings?
- TAC identifies the series of angular contact thrust ball bearings. The number ahead of it gives the bore diameter in millimeters, while the code after it defines the contact angle and internal design, as seen in 15TAC02D or 40TAC03D.
- Can they be mounted in any position?
- No. These bearings take axial load in one direction, so orientation matters during mounting. Where loads come from both directions, they are installed in pairs. Alignment and preload are critical to correct operation.
- How do I request a quote for a specific size?
- Send the complete part number or the dimensions you require by WhatsApp or email. We reply promptly and can indicate a compatible alternative where one applies. The TAC series is available in various sizes.
