Barden 109HCRRUL Double Angular Contact Precision Bearing

The Barden 109HCRRUL Double Angular Contact Precision Bearing is a high-precision angular-contact ball bearing with a 45 mm bore, 75 mm outer diameter, and 17 mm width (45x75x17 mm). It belongs to Barden's 109H family, a line of precision angular-contact bearings manufactured under the Schaeffler umbrella, designed for tight tolerances in demanding rotational applications. The design supports duplex mounting in configurations such as back-to-back (DB), face-to-face (DF), and tandem (DT) to increase stiffness and thrust capacity in precision machinery, including spindle assemblies and other high-precision equipment. Verified listings show the 109HCRRUL part number and footprint, although some retailers mark this specific variant as discontinued, so availability may be limited. As a general class, Barden angular-contact bearings are used in precision tools and machinery where accurate radial load handling and axial stiffness are required, and the 109H series is commonly specified where tight tolerances and repeatability matter.
