BARDEN 105HCDULO11 Ball Bearing Set Radial High Precision

BARDEN 105HCDULO11 Ball Bearing Set Radial High Precision is a Barden (Schaeffler) spindle bearing from the company’s high‑precision angular‑contact line, designed for precision machine tools and spindle assemblies where stiffness, accuracy, and repeatability matter. The bearing has a 25 mm bore, 47 mm outer diameter, and 12 mm width, with a 15° contact angle and an O‑11 radial clearance, and it is supplied with a single‑seal configuration and a P2PF lubrication designation as part of its model code. This single‑sealed, angular‑contact design supports high running accuracy at speed, making it suitable for light‑duty spindle tasks or toolholding applications in precision machinery. Rated for dynamic loads around 14.6 kN and static loads near 9.15 kN, it delivers reliable performance under typical spindle loading conditions. Some distributors list this exact variant as discontinued, so availability may vary by region; when in stock, it is used in legacy spindles and precision machine tools that require tight tolerances and consistent rotational stability. The 105HCDULO11 designation places it in Barden’s family of precision bearings (Schäffler), known for high‑precision, single‑row angular‑contact designs used in tool spindles and similar applications.
