How the 7220-BECBP model number is decoded

7220 BECBP is SKF's 100 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 100×180×34 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 100×180×34 mm (3.937×7.087×1.339 in), 40.0 mm radial section height, C 143 kN, C0 134 kN, Pu 4.75 kN.reference speed 4,300 r/min (thermal) and limiting speed 4,500 r/min (mechanical), catalogue mass 3300 g. The 4.75 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 143/134 kN ratings and 3300 g mass this execution carries about 1.43 kN of C per millimetre of bore. Mass and section check: 3300 g inside the 100×180×34 mm outline leaves a 40.0 mm radial section, and the 134 kN static rating is 0.94× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Speed-ratio note for this exact unit: the reference speed is 4,300 r/min against a 4,500 r/min limiting speed, i.e. a reference-to-limit ratio of 0.96. 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

• One 7220-BECBP locates the shaft in one axial direction only; reversing-thrust positions need a DB or DF pair — or a double-row bearing — with preload set from the load diagram, never from assembly feel.
• 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.
• 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.
• Fillet radii must clear the chamfer so the 34 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• The steep 40° angle of 7220-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.
