Industrial 103H High Precision Angular Contact Ball Bearing

The Barden 103H angular contact ball bearing is a high‑precision, single‑row bearing from Barden (Schaeffler) designed for spindle and precision machine‑tool applications. It features a 17 mm bore, 35 mm outer diameter and 10 mm width, with a 15° contact angle that enables effective axial and radial load handling while preserving stiffness and accuracy at higher speeds. The 103H designation identifies a high‑precision variant within Barden’s angular‑contact family, and available configurations include sealed versions such as the 103HCDUL that provide single‑seal protection without changing the basic 17×35×10 mm geometry. Barden bearings are recognized for tight tolerances and stable performance in machine tools, spindles, robotics, and other high‑precision axes, thanks to robust cage design and consistent preload retention. For spindle or precision‑axis use, this bearing supports accurate runout and load distribution across speed ranges, delivering reliable, repeatable performance in demanding manufacturing equipment.
