SKF 7019 CDGA/P4 is a super-precision, high-capacity single row angular contact ball bearing from the SKF 70 series. It is universally matchable and can be combined back-to-back, face-to-face or in tandem to give a predetermined extra light preload without shims.
7019 — 70 series angular contact ball bearing, 95 mm bore, 145 mm outside diameter.
CD — high-capacity D design with a 15° contact angle.
GA — single bearing for universal matching, extra light preload.
P4 — ISO P4 tolerance class, equivalent to ABEC 7.
