How the 7222-BECBY model number is decoded

7222 BECBY is SKF's 110 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 110×200×38 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. stamped brass cage, ball-centred (suffix Y) — lighter than the machined M cage but brass rather than polymer. 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. BECBY combines the optimized 40° geometry with CB universal clearance and a stamped brass Y cage. Envelope 110×200×38 mm (4.331×7.874×1.496 in), 45.0 mm radial section height, C 163 kN, C0 156 kN, Pu 5.3 kN.reference speed 4,000 r/min (thermal) and limiting speed 4,000 r/min (mechanical), which coincide for this size, catalogue mass 4600 g. Sizing arithmetic on the 110 mm bore: 163 kN C divided by the 45.0 mm radial section height gives 3.6 kN per section millimetre; the 4600 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Envelope economics: the 38 mm width over a 45.0 mm section yields 0.84 mm of ring width per section millimetre, and the bearing weighs 4600 g for 163 kN of dynamic capacity — about 28 g per rated kN. Bore-to-OD planning: OD 200 over bore 110 is a 1.82× step for this size, and the 38 mm width gives a bore/width ratio of 2.89; use these ratios when housing space around the 110 mm shaft is the first constraint. Cage detail specific to this order number: the Y cage is stamped from brass strip into ball pockets rather than machined from solid, giving a lighter cage assembly and lower centrifugal mass than the M execution; it remains brass (temperature and oil-additive tolerant, unlike PA66) but is the formed-cage design, and the machined-brass BECBM order number remains the choice for severe shock or marginal lubrication.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Assign interference to the rotating ring — roughly m6 on a 110 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• 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.
• 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 m6 on a 110 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• The steep 40° angle of 7222-BECBY 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 BECBY 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.
