How the 7322-BEY model number is decoded

7322 BEY 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. stamped brass cage, ball-centred (suffix Y) — lighter than the machined M cage but brass rather than polymer. The BEY is a basic single bearing with a stamped brass Y cage — a single unit, not a universally matchable one.. Envelope 110×240×50 mm (4.331×9.449×1.969 in), 65.0 mm radial section height, C 225 kN, C0 224 kN, Pu 7.2 kN.reference speed 3,400 r/min (thermal) and limiting speed 3,200 r/min (mechanical), catalogue mass 10000 g. Envelope economics: the 50 mm width over a 65.0 mm section yields 0.77 mm of ring width per section millimetre, and the bearing weighs 10000 g for 225 kN of dynamic capacity — about 44 g per rated kN. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 3,200 r/min while thermal balance under catalogue load sets the 3,400 r/min reference; at dm ≈ 175.0 mm the corresponding dn is approximately 560k mm·r/min. 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. Ordering note: BEY is the basic single bearing with the stamped brass strip cage (Y) — light and oil-additive tolerant, but not ground on the side faces for set mounting; order BECBY for a universally matchable stamped-brass unit.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• Preload the set against a calculated stand-off dimension — the ground faces of BEY 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 BEY establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• 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 7322-BEY 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.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 7322 BEY as the single basic stamped brass execution; the other order numbers of the 7322 size are different products and may carry different ratings — always quote the full designation when purchasing.
