For machine tool spindles, rotary tables and measuring equipment that demand high axial rigidity, the NTN 2A-BST series angular contact thrust ball bearing is a single-direction solution. It handles high axial loads with a capacity greater than standard thrust ball bearings. MR Industrial Accessories supplies this series to customers across the US, Canada, Mexico and South America.

Reading the part number: the 2A prefix denotes a two-row angular contact design, BST signals the angular contact thrust ball series, and the following digits give bore and outside diameter in millimeters. A 1BLXL suffix points to a variant with light preload and high-speed lubrication.

Typical installations include machine tool main spindles, milling heads, coordinate tables, precision measuring equipment and positioning systems where axial movement must be tightly controlled. The single-direction load capability suits setups that require accurate axial displacement control.

Selection depends on axial load direction, magnitude and rotational speed. Proper mounting calls for precise shaft-to-housing alignment because these bearings are sensitive to misalignment. Use suitable grease or oil lubrication and verify axial clearance for the operating conditions. In contaminated environments, choose configurations with additional sealing.

Interchangeability: NTN angular contact thrust ball bearings can be replaced by equivalents from other brands that follow the same dimensional nomenclature, provided tolerances and load capacities match. Always confirm critical dimensions and operating conditions before substituting brands. For an exact equivalent, consult a specialist who can review the full part number and specifications.
