SKF 5207-EC3 Double Row Deep Groove Ball Bearing

SKF 5207-EC3 is a double-row angular contact ball bearing engineered to support substantial radial and axial loads while preserving smooth rotation and precise shaft alignment in electric motors, pumps, gearboxes, conveyors, and related industrial machinery. The EC3 designation denotes an optimized internal geometry with greater-than-normal clearance (C3), making it suitable for applications with elevated operating temperatures or interference fits. Key specifications include a bore diameter of 35 mm, outside diameter of 72 mm, and width of 27 mm, with a 30° contact angle, a pressed steel cage, and an open bearing that can be lubricated by grease or oil; its dynamic load rating is 40.5 kN and static load rating is 30 kN, with a limiting speed of 6,300 rpm and an approximate weight of 0.46 kg. This bearing is identified by the MPN 5207-EC3 and is manufactured by SKF, featuring a double-row design and an internal design designation of E (Optimized Internal Geometry).
