SKF 7022-CD/P4ADGA super-precision angular contact ball bearings. Bore 110 mm, outside diameter 170 mm, width 28 mm per bearing. ISO 70 series, size 7022, straight bore, open both faces.
Contact Angle: 15°, from the SKF CD code. Design: high-capacity D execution. Precision Class: P4A. Preload: extra light, from the DGA suffix. Matching: universally matchable, so the pair mounts back-to-back, face-to-face or in tandem. Cage Material: non-metallic. Series: ISO 70. Base Number: 7022. Also catalogued as 7022 CDGA/P4A.
Dynamic Load Rating Cr: 111 kN. Static Load Rating C0r: 108 kN. Fatigue load limit Pu: 3.9 kN. Unmounted preload G0: 420 N. Axial stiffness: 122 N/µm. Ball diameter 19.05 mm, 20 balls. Effective load centre a: 32.9 mm. Mass: 1.93 kg. Grease reference quantity: 25.5 cm³.
A 15° contact angle favours speed and radial load over thrust, which is the usual front-position choice on a machine tool spindle. The DGA set is built to an extra light preload, with 122 N/µm of axial stiffness. Universal matching means the two bearings arrive at that preload in any orientation with no spacer grinding. On this 70-series light section the static rating sits close to the dynamic rating, which is normal for the section.
Two bearings, universally matchable to extra light preload. Each carries the ratings above on its own; mounted as a pair they share load according to the arrangement chosen.
Shaft abutment diameter da and db: 119 mm minimum. Housing abutment diameter Da: 161 mm maximum, Db: 165 mm maximum. Housing fillet radius ra: 2 mm maximum, rb: 1 mm maximum. Oil-nozzle diameter dn: 132.6 mm.
Fafnir 2MM9122WI is the Timken cross on this envelope at the same 15° angle. GMN S6022CTA covers the same size. NSK 7022CTYNSULP4 shares the size and angle with a polyamide cage, so it is a related size.
