How the 7212-ACCBM model number is decoded
7212 ACCBM is SKF's 60 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 25° (AC) contact angle, 60×110×22 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 60×110×22 mm (2.362×4.331×0.866 in), 25.0 mm radial section height, C 69.5 kN, C0 56 kN, Pu 2.36 kN.reference speed 8,000 r/min (thermal) and limiting speed 11,000 r/min (mechanical), catalogue mass 800 g. Load balance: C0 56 kN against C 69.5 kN gives a 0.81 ratio, typical of a steep-angle axial-oriented design; Pu 2.36 kN enters the SKF adjusted-life equation rather than the basic rating life. Sizing arithmetic on the 60 mm bore: 69.5 kN C divided by the 25.0 mm radial section height gives 2.8 kN per section millimetre; the 800 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Bore-to-OD planning: OD 110 over bore 60 is a 1.83× step for this size, and the 22 mm width gives a bore/width ratio of 2.73; use these ratios when housing space around the 60 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
Common applications
- vibrating screens and shale shaker shafts
- centrifuge and separator drives
- heavy feed and take-up rolls
Known failure patterns
- false brinelling on idle paired sets exposed to machine vibration
- contact-angle shift and edge loading after uneven locknut torque tilts the set
- raceway smearing under minimum-axial-load starvation at light load and high speed
- ball unloading when the 25-degree AC set is applied at the Fa/Fr ratios valid only for the 40-degree B design
- electrical pitting on VFD-driven shafts without grounding protection
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- 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.
- Do not mix execution classes inside one set: a universally matchable ACCBM unit is ground for arbitrary pairing, a basic execution is not.
- 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.
- At 60 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 7212-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.
Frequently asked questions
What are the dimensions and catalogue data of 7212-ACCBM?
7212 ACCBM measures 60 mm bore × 110 mm OD × 22 mm width (2.362 × 4.331 × 0.866 in), mass about 800 g. SKF 17000 ratings: C 69.5 kN, C0 56 kN, Pu 2.36 kN, reference speed 8,000 r/min (thermal) and limiting speed 11,000 r/min (mechanical).
What does the ACCBM suffix mean?
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.
Can one 7212-ACCBM take thrust in both directions?
No. A single-row angular-contact bearing reacts axial load in one direction; reversing thrust needs a DB/DF matched pair (use a universally matchable CB/GA execution) or a double-row bearing. Under radial load the 25° angle induces an axial force that the arrangement must balance.
What minimum axial load does 7212-ACCBM need?
The balls must remain seated: SKF gives Fam ≈ A·(n·dm/1000)² and a load-ratio guideline of Fa/Fr ≥ 1 for the 40° B execution and ≥ 0,55 for the 25° AC execution. Preloaded pairs and spring loading are the usual ways of meeting it at light load and high speed.
