Barden 211HDL Precision Angular Contact Bearing Set

The Barden 211HDL Precision Angular Contact Bearing Set is a duplex pair of single‑row angular contact ball bearings designed for high‑precision spindle support in machine tools. Each bearing has a 55 mm bore and 100 mm outer diameter; the duplex total width is 42 mm (21 mm per bearing) with a 15° contact angle to support combined radial and axial loads at high speed. HDL denotes an H Textile Laminated Phenolic Resin cage with Duplex pairing and Light Preload, and the bearings are unsealed with standard lubrication, offering ABEC 7–9 (extra precision) performance. Typical applications include machine‑tool spindles and precision manufacturing equipment that require a matched, preloaded angular contact bearing pair for rigid, repeatable operation.
