SKF 7014CD/P4ADGA Precision Angular Contact Ball Bearing

The SKF 7014CD/P4ADGA is a 70x110x40 mm single-row super-precision angular contact ball bearing with a 15° contact angle, designed for spindle and high-speed machine-tool applications requiring high rigidity and precision. It carries a P4A tolerance class and is an open bearing (no seal), suitable for clean environments and lubricated operation common in precision spindles. The bearing weighs about 1.19 kg and uses 19 balls with a diameter of 12.7 mm. Main dimensions are bore 70 mm, outer diameter 110 mm, and width 40 mm. Dynamic load rating is 18,720 lbf (83 kN) and static load rating is 20,588 lbf (92 kN), with a limiting speed up to 22,000 rpm. The operating temperature range is -30°C to 110°C. As part of SKF's 7000 series, it is described as a super-precision angular contact bearing and is often sold as a universally matched pair for increased stiffness in dual-bearing spindle configurations.
