Barden Precision Bearings 216HDL Precision Bearing

The Barden 216HDL precision bearing is a high-precision angular contact ball bearing from Barden, a Schaeffler brand, engineered for spindle and precision-tooling applications where axial and radial rigidity matter. The 216HDL designation places it in Barden’s HDL family of angular contact bearings; it’s a member of the 216 series that are commonly used in machine tool spindles, precision ball-screw supports, robotics, and medical equipment. Barden supplies HDL variants with a range of cage materials and lubrication options to meet demanding operating conditions, enabling tight tolerances and stable performance at high speeds. Exact specifications—such as bore, outer diameter, width, dynamic and static load ratings, cage design, lubrication, and preload options—are defined for each variant in the official Barden catalog and by authorized distributors, ensuring a fit for replacement or new assemblies. The 216HDL is typically purchased for spindle rehab, precision automation components, and other equipment where compact size and consistent runout are required, supporting long-term accuracy and repeatability in high-precision environments.
