SKF 7010 ACDGA/P4A super-precision angular contact ball bearing. Bore Diameter: 50 mm. Outside Diameter: 80 mm. Width: 16 mm. Series: 7000, light section. Base Number: 7010. Single row, open, bearing steel rings and balls. Contact Angle: 25°. Cage: machined fabric-base laminate phenolic, outer-ring guided. Preload: extra light. Precision Class: ISO P4 / ABEC 7. Mass: 0.251 kg. GTIN: 7316570650259.
7010 — SKF 7000 series, light section, 50 mm bore.
ACD — 25° contact angle with a machined phenolic cage, outer-ring guided.
GA — extra light preload (GB light, GC medium).
P4A — ISO P4 / ABEC 7 precision, universally matchable so any two pieces pair up in any orientation.
Dynamic Load Rating: 26.6 kN. Static Load Rating: 22.8 kN. Limiting Speed: 18,000 rpm. Operating Temperature: –30 to +100 °C. Number Of Rows: 1. Seal Type: Open. Bore Type: Straight. Condition: New – Open box.
50 x 80 x 16 mm. A 25° contact angle carries more thrust and less speed than a 15° bearing of the same envelope, which suits spindles with substantial axial cutting load. Extra light preload is ground into the ring faces, so a pair set up solid carries its preload without shims or spacers.
Equivalents at the same envelope and angle: Fafnir 3MM9110WI-DUL, GMN S6010 E TA A7, FAG B7010-E-T-P4S-UL. The 7010 CDGA/P4A is a related size at 15°. The 7010 ACDGB/P4A and 7010 ACDGC/P4A are the same envelope at light and medium preload.
25°, from the ACD position of the designation.
Extra light, from the GA position.
