SKF 7210 ACD P4ADGA Super-Precision Angular Contact Bearing

SKF 7210 ACD/P4ADGA is a super‑precision, single‑row angular contact ball bearing set designed for high‑accuracy spindles and precision machinery. It is marketed as a universally matched, D‑design pairable bearing, comprising two single‑row angular contact bearings that can be used as a matched pair in tandem or back‑to‑back configurations for enhanced rigidity and balanced load distribution. Featuring a 50 mm bore and 90 mm outer diameter with open construction, it has a 25° contact angle and a radial clearance of C0 to support light preload and precise shaft positioning in demanding applications. The P4 designation indicates a high‑precision class suitable for machine‑tool and CNC spindle work, and the two‑piece, pairable design is commonly used to simplify alignment and installation in precision equipment.
