How the 7212-BECBP model number is decoded

7212 BECBP is SKF's 60 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 60×110×22 mm to the ISO dimension plan. 40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. 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 61 kN, C0 50 kN, Pu 2.12 kN.reference speed 7,000 r/min (thermal) and limiting speed 7,500 r/min (mechanical), catalogue mass 800 g. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 7,500 r/min while thermal balance under catalogue load sets the 7,000 r/min reference; at dm ≈ 85.0 mm the corresponding dn is approximately 638k mm·r/min. Selection figures for 7212 BECBP: the static-to-dynamic ratio C0/C is 0.82, Pu 2.12 kN is about 3 % of C, and catalogue mass works out to roughly 13 g per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 7,000 r/min against a 7,500 r/min limiting speed, i.e. a reference-to-limit ratio of 0.93. Universal polymer-cage execution: BECBP is the factory-ground set-mounting version of the basic BEP — both side faces are finish-ground to a controlled stand-off so two units form DB, DF or DT arrangements without shims, while the glass-fibre PA66 ball-centred cage keeps the light, quiet running typical of the P-cage range; CB delivers Normal axial clearance before preload is applied at assembly.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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.
• Assign interference to the rotating ring — roughly k5 on a 60 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• DB pairs give the highest moment stiffness, DF pairs tolerate misalignment and thermal expansion better, DT shares heavy one-direction thrust; choose from the shaft thermal calculation rather than by habit.
• The steep 40° angle of 7212-BECBP favours thrust-heavy combined loads; for a predominantly radial high-speed position the 25° ACCBM execution of the same size is the alternative order number.
• Universally matchable BECBP 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.
