SKF 71908CDP4ADGA High Precision Deep Groove Ball Bearing

SKF 71908CDP4ADGA is a single-row, super-precision angular contact ball bearing designed for high-speed, high-accuracy equipment. It has a bore of 40 mm, an outer diameter of 62 mm, and a width of 24 mm, packaged in an open configuration with a 15° contact angle to support axial loads alongside radial loads at speed. The bearing carries the P4A precision class designation and the CDP4ADGA suffix, indicating SKF's tight tolerance and manufacturing standards for demanding applications. The radial internal clearance is C0, providing a stable baseline for precise positioning across varying temperatures and rotational speeds. This combination of precise geometry, open design, and robust steel raceway makes it well suited for precision spindle assemblies, high-accuracy machine tools, and other equipment where consistent rotation and minimal runout are critical. When integrating, ensure mounting hardware and housings are compatible with a 40x62x24 mm angular contact unit in the CDP4ADGA family and confirm preload requirements per the equipment manual to maintain optimal performance.
