How the 7207-BEP model number is decoded

7207 BEP is SKF's 35 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 35×72×17 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 35×72×17 mm (1.378×2.835×0.669 in), 18.5 mm radial section height, C 29.1 kN, C0 19 kN, Pu 0.815 kN.reference speed 11,000 r/min (thermal) and limiting speed 11,000 r/min (mechanical), which coincide for this size, catalogue mass 280 g. Selection figures for 7207 BEP: the static-to-dynamic ratio C0/C is 0.65, Pu 0.815 kN is about 3 % of C, and catalogue mass works out to roughly 8 g per millimetre of bore. Load balance: C0 19 kN against C 29.1 kN gives a 0.65 ratio, typical of a steep-angle axial-oriented design; Pu 0.815 kN enters the SKF adjusted-life equation rather than the basic rating life. Speed-ratio note for this exact unit: the reference speed is 11,000 r/min against a 11,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. 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

• 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.
• 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.
• 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.
• The steep 40° angle of 7207-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 7207 BEP as the single basic pa66 execution; the other order numbers of the 7207 size are different products and may carry different ratings — always quote the full designation when purchasing.
