Barden Bearings L150HDF1500 Precision Bearing

The Barden L150HDF1500 Precision Bearing is a duplex angular contact ball bearing pair from the L (Light) series, designed for high-precision machine tools such as spindles and ball-screw supports. It accommodates a 1.5000 in bore, a 2.8346 in outer diameter (72 mm), and a 0.6250 in width, making it a compact choice for tight tool-space installations while preserving accurate load distribution. The assembly carries a standard preload of 1500 pounds and is configured as a duplex unit to share axial and radial loads and enhance overall stiffness in high-speed operation. Common applications include precision spindles, precision ball-screw supports, robotics, and metrology equipment where tight tolerances, repeatability, and long-term stability matter. As a Barden precision bearing, this duplex angular contact pair is intended for back-to-back or face-to-face mounting to achieve reliable alignment in critical tool paths.
