How the 7207-ACCBM model number is decoded

7207 ACCBM is SKF's 35 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 25° (AC) contact angle, 35×72×17 mm to the ISO dimension plan. AC sets the 25° contact angle, CB marks universal matching with Normal axial clearance, and M the machined brass ball-centred cage. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. Envelope 35×72×17 mm (1.378×2.835×0.669 in), 18.5 mm radial section height, C 35.5 kN, C0 23.2 kN, Pu 0.98 kN.reference speed 12,000 r/min (thermal) and limiting speed 18,000 r/min (mechanical), catalogue mass 280 g. The 0.98 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 35.5/23.2 kN ratings and 280 g mass this execution carries about 1.01 kN of C per millimetre of bore. Load balance: C0 23.2 kN against C 35.5 kN gives a 0.65 ratio, typical of a steep-angle axial-oriented design; Pu 0.98 kN enters the SKF adjusted-life equation rather than the basic rating life. Bore-to-OD planning: OD 72 over bore 35 is a 2.06× step for this size, and the 17 mm width gives a bore/width ratio of 2.06; use these ratios when housing space around the 35 mm shaft is the first constraint. High-angle alternative note: ACCBM carries the 25-degree AC contact angle (not the 40-degree B), CB Normal-clearance universal faces and a machined brass cage; it runs faster and cooler than a BECBM of the same envelope but accepts a smaller axial share, so substitute only after re-running the load-ratio check.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Greased positions should fill roughly 25–35 % of the free volume on a 7207-ACCBM of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Preload the set against a calculated stand-off dimension — the ground faces of ACCBM establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• Assign interference to the rotating ring — roughly k5 on a 35 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• Reference and limiting speeds are different ceilings: design to both, and remember preload and oil/air cooling move the real thermal limit far from the catalogue reference value.
• The 25° AC angle of 7207-ACCBM runs faster and cooler than a 40° B bearing of the same envelope, but its thrust capacity and induced-load behaviour differ — do not swap AC for B without re-running the axial-load calculation.
• Universally matchable ACCBM bearings arrive ready for set mounting, not preloaded sets: preload results from how the set is clamped, so follow the SKF stand-off-ring and nut-torque procedure.
