How the 7222-BEP model number is decoded

7222 BEP 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. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units.. Envelope 110×200×38 mm (4.331×7.874×1.496 in), 45.0 mm radial section height, C 153 kN, C0 143 kN, Pu 4.9 kN.reference speed 4,000 r/min (thermal) and limiting speed 3,600 r/min (mechanical), catalogue mass 4600 g. The 4.9 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 153/143 kN ratings and 4600 g mass this execution carries about 1.39 kN of C per millimetre of bore. Selection figures for 7222 BEP: the static-to-dynamic ratio C0/C is 0.93, Pu 4.9 kN is about 3 % of C, and catalogue mass works out to roughly 42 g per millimetre of bore. 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. Basic polymer-cage execution: BEP is delivered as an individual open bearing with the 40-degree optimized internals and a glass-fibre PA66 ball-centred cage; it is not ground on the side faces for arbitrary pairing, so a reversing-thrust position should order BECBP for a set rather than mounting two unmatched BEP units.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Greased positions should fill roughly 25–35 % of the free volume on a 7222-BEP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Do not mix execution classes inside one set: a universally matchable BEP unit is ground for arbitrary pairing, a basic execution is not.
• DB pairs give the highest moment stiffness, DF pairs tolerate misalignment and thermal expansion better, DT shares heavy one-direction thrust; choose from the shaft thermal calculation rather than by habit.
• 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-BEP 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 7222 BEP as the single basic pa66 execution; the other order numbers of the 7222 size are different products and may carry different ratings — always quote the full designation when purchasing.
