Barden 105H DM Thrust Angular Contact Ball Bearing

The Barden 105H DM thrust angular contact ball bearing is a compact, single‑row open bearing designed to carry axial loads in precision spindles and machine tools, delivering high rigidity with a small footprint for tight tooling envelopes. It measures 25 mm bore, 47 mm outer diameter, and 12 mm width, features a 15-degree contact angle, and offers a dynamic load rating of 11,379 N with a static radial rating of 8,058 N, making it well-suited for high-precision thrust duties under combined loads. The parts are built with 100Cr6 rings, steel balls, and a phenolic cage in a one-piece halo configuration; the open design is compatible with oil or grease lubrication, with limiting speeds up to 51,000 min-1 (oil) or 33,000 min-1 (grease), and preload options of 50 N (L), 130 N (M), and 265 N (S) to tailor axial stiffness. Commonly used in precision machine tools and spindles where reliable axial support and rigidity are essential, the 105H DM is designed to be paired with other angular-contact bearings in duplex arrangements to meet higher thrust capacities.
