How the 7315-BEP model number is decoded

7315 BEP is SKF's 75 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 75×160×37 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 75×160×37 mm (2.953×6.299×1.457 in), 42.5 mm radial section height, C 125 kN, C0 98 kN, Pu 3.8 kN.reference speed 5,300 r/min (thermal) and limiting speed 5,000 r/min (mechanical), catalogue mass 3200 g. Selection figures for 7315 BEP: the static-to-dynamic ratio C0/C is 0.78, Pu 3.8 kN is about 3 % of C, and catalogue mass works out to roughly 43 g per millimetre of bore. Load balance: C0 98 kN against C 125 kN gives a 0.78 ratio, typical of a steep-angle axial-oriented design; Pu 3.8 kN enters the SKF adjusted-life equation rather than the basic rating life. Bore-to-OD planning: OD 160 over bore 75 is a 2.13× step for this size, and the 37 mm width gives a bore/width ratio of 2.03; use these ratios when housing space around the 75 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

• 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.
• At 75 mm bore the k5 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.
• 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.
• One 7315-BEP 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.
• The steep 40° angle of 7315-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 7315 BEP as the single basic pa66 execution; the other order numbers of the 7315 size are different products and may carry different ratings — always quote the full designation when purchasing.
