The SKF 7040ACDGAP4A is a high-precision angular contact ball bearing, specifically designed for applications requiring high accuracy, rigidity, and high-speed operation. Featuring a 25° contact angle (AC) and P4A precision class, it ensures optimal performance in demanding industrial environments. This universally matchable (DGA) bearing is supplied with a light preload (GA), making it suitable for mounting in duplex arrangements (back-to-back, face-to-face, or tandem) without shims. Its robust design, often with a machined brass cage, and high-quality construction contribute to extended service life and reliable operation in machine tools, pumps, and other precision machinery.
