Description

NTN 2A-BST40X90-1BLXL is a thrust ball bearing de contacto angular reference, within Bearings. Request a quote for 2A-BST40X90-1BLXL via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The NTN 2A-BST series angular contact thrust ball bearing is a component designed to carry high axial loads in a single direction, with a load capacity higher than that of conventional thrust ball bearings. It is used in applications requiring high axial rigidity and precision, such as machine tool spindles, rotary tables and measuring equipment. MR Accesorios Industriales sells this series backed by more than 80 years in the Argentine industrial market.

The 2A-BST series designation is interpreted as follows: the prefix 2A indicates the two-row angular contact design, while BST identifies the angular contact thrust ball series. The numbers that follow, as in 2A-BST17X47-1BLXL, correspond to the bore diameter and the outer diameter in millimeters (17 and 47 respectively). The suffix 1BLXL indicates an execution with light preload and high-speed lubrication. Other examples such as 2A-BST40X90-1BLXL show the variety of available sizes.

These bearings are typically used in machine tool main spindles, milling machine heads, coordinate tables, precision measuring equipment and positioning systems that require high axial rigidity. In Argentine industry, they are found in the metalworking, automotive and aerospace sectors and in the manufacture of precision machinery. Their ability to carry axial loads in a single direction makes them ideal for applications where axial displacement must be controlled accurately.

To correctly select a bearing from this series, it is essential to consider the direction of the axial load, its magnitude and the rotation speed. Mounting requires precise alignment between the shaft and the housing, since these bearings are sensitive to misalignment. It is recommended to use adequate lubrication, whether grease or oil, and to verify the axial clearance according to the operating conditions. Sealing will depend on the environment: in contaminated environments, configurations with additional protection should be chosen.

As for equivalents and interchangeability, NTN angular contact thrust ball bearings can be replaced by products from other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK, as long as the tolerances and load capacities are respected. It is important to verify the critical dimensions and the operating conditions before replacing one brand with another. For an exact equivalent, it is advisable to consult a specialist who can analyze the complete part number and the technical specifications.

Frequently Asked Questions

What does the 1BLXL suffix mean in 2A-BST bearings?
The 1BLXL suffix indicates a special execution with light preload and lubrication for high speeds. This configuration improves rigidity and reduces noise in precision applications.
Can I replace an NTN 2A-BST bearing with one from another brand?
Yes, as long as the other brand offers an angular contact thrust ball bearing with the same dimensions and load capacity. It is important to verify the tolerances and the mounting type.
How do I request a quote for a specific size in the 2A-BST series?
Write to us by WhatsApp with the complete part number or the bore and outer diameters you need. We will send you a quote shortly and tell you the availability.
