How the 7322-BECBP model number is decoded

7322 BECBP is SKF's 110 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 110×240×50 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 110×240×50 mm (4.331×9.449×1.969 in), 65.0 mm radial section height, C 240 kN, C0 245 kN, Pu 7.8 kN.reference speed 3,400 r/min (thermal) and limiting speed 3,600 r/min (mechanical), catalogue mass 10000 g. At the printed limiting speed of 3,600 r/min the mean pitch diameter dm ≈ 175.0 mm implies a dn value around 630k mm·r/min; the 3,400 r/min reference speed is the thermal-planning figure under catalogue load. Selection figures for 7322 BECBP: the static-to-dynamic ratio C0/C is 1.02, Pu 7.8 kN is about 3 % of C, and catalogue mass works out to roughly 91 g per millimetre of bore. Bore-to-OD planning: OD 240 over bore 110 is a 2.18× step for this size, and the 50 mm width gives a bore/width ratio of 2.20; use these ratios when housing space around the 110 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

• At 110 mm bore the m6 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.
• One 7322-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.
• Greased positions should fill roughly 25–35 % of the free volume on a 7322-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• 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.
• The steep 40° angle of 7322-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.
