Barden 108HC Angular Contact Super Precision Bearing

Barden 108HC Angular Contact Super Precision Bearing is a high-accuracy, single‑row angular‑contact ball bearing from Barden’s renowned Super Precision line, engineered for spindle and high‑speed machinery where tight runout and long life are critical. The bearing features a 40 mm bore and 68 mm outer diameter, placing it within Barden’s 108H family of compact, precision components designed for demanding applications. Its angular‑contact geometry enables handling of both radial loads and thrust within a serviceable duplex configuration, and it is commonly paired in pre‑load arrangements in back‑to‑back (DB), face‑to‑face (DF), or tandem (DT) setups to achieve higher stiffness and load capacity. Built to maintain accuracy under high rotational speeds, the 108HC variant inherits the specification discipline and manufacturing precision that characterize Barden’s premium bearings, making it suitable for precision spindles, high‑speed machine tools, and other equipment where deterministic performance is essential. This bearing represents a straightforward, reliable solution when a compact, ultra‑precise angular‑contact component is required to support demanding spindle programs and other precision mechanisms.
