How the 7213-ACCBM model number is decoded

7213 ACCBM is SKF's 65 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 25° (AC) contact angle, 65×120×23 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 65×120×23 mm (2.559×4.724×0.906 in), 27.5 mm radial section height, C 81.5 kN, C0 65.5 kN, Pu 2.8 kN.reference speed 7,000 r/min (thermal) and limiting speed 10,000 r/min (mechanical), catalogue mass 1000 g. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 10,000 r/min while thermal balance under catalogue load sets the 7,000 r/min reference; at dm ≈ 92.5 mm the corresponding dn is approximately 925k mm·r/min. Selection figures for 7213 ACCBM: the static-to-dynamic ratio C0/C is 0.80, Pu 2.8 kN is about 3 % of C, and catalogue mass works out to roughly 15 g per millimetre of bore. Bore-to-OD planning: OD 120 over bore 65 is a 1.85× step for this size, and the 23 mm width gives a bore/width ratio of 2.83; use these ratios when housing space around the 65 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

• Mount by induction-heating the inner ring to max 120 °C; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• Mount by induction-heating the inner ring to max 120 °C; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• 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.
• At 65 mm bore the k5 seat assumes a steel shaft and housing; aluminium housings grow faster with temperature, so re-check the outer-ring setting when the case is non-ferrous.
• The 25° AC angle of 7213-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.
