How the 7204-BECBP model number is decoded

7204 BECBP is SKF's 20 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 20×47×14 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 20×47×14 mm (0.787×1.85×0.551 in), 13.5 mm radial section height, C 14.3 kN, C0 8.15 kN, Pu 0.345 kN.reference speed 19,000 r/min (thermal) and limiting speed 19,000 r/min (mechanical), which coincide for this size, catalogue mass 110 g. Mass and section check: 110 g inside the 20×47×14 mm outline leaves a 13.5 mm radial section, and the 8.15 kN static rating is 0.57× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. The 0.345 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 14.3/8.15 kN ratings and 110 g mass this execution carries about 0.72 kN of C per millimetre of bore. Bore-to-OD planning: OD 47 over bore 20 is a 2.35× step for this size, and the 14 mm width gives a bore/width ratio of 1.43; use these ratios when housing space around the 20 mm shaft is the first constraint. 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

• Preload the set against a calculated stand-off dimension — the ground faces of BECBP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• At 20 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.
• At 20 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.
• 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.
• The steep 40° angle of 7204-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.
