How the 7213-BECBP model number is decoded

7213 BECBP is SKF's 65 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 65×120×23 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 65×120×23 mm (2.559×4.724×0.906 in), 27.5 mm radial section height, C 69.5 kN, C0 57 kN, Pu 2.45 kN.reference speed 6,700 r/min (thermal) and limiting speed 6,700 r/min (mechanical), which coincide for this size, catalogue mass 1000 g. Mass and section check: 1000 g inside the 65×120×23 mm outline leaves a 27.5 mm radial section, and the 57 kN static rating is 0.82× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. The 2.45 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 69.5/57 kN ratings and 1000 g mass this execution carries about 1.07 kN of C per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 6,700 r/min against a 6,700 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. 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

• Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
• 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.
• Mount by induction-heating the inner ring to max 120 °C — the PA66 cage sets the ceiling, not the steel; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• 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 7213-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.
