Barden 203HCDUL O-11 -2 -1 110830 Precision Bearing Set

Two Barden precision angular-contact spindle bearings (203HCDUL) in a dedicated O-11 bearing set, part number 110830, designed for light-duty machine-tool spindles. Each bearing features a 17 mm bore, 40 mm outside diameter, and 12 mm width, with a 15-degree contact angle and a two-row configuration for combined axial and radial support in a compact package. The set includes two bearings (1 pair) and carries a dynamic load rating of 10.8 kN and a static load rating of 5.85 kN, making it suitable for tandem installations where reliable load sharing and stiffness matter. This 110830 variant identifies the exact two-bearings combination used in spindle assemblies requiring tight tolerances and the ability to sustain high speeds in precision machining environments. Manufactured by Barden (Schaeffler), these angular-contact bearings are intended for spindle applications where accurate rotation and stable performance are required.
