How the 7217-BEP model number is decoded

7217 BEP is SKF's 85 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 85×150×28 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 85×150×28 mm (3.346×5.906×1.102 in), 32.5 mm radial section height, C 95.6 kN, C0 83 kN, Pu 3.25 kN.reference speed 5,300 r/min (thermal) and limiting speed 5,000 r/min (mechanical), catalogue mass 1850 g. Sizing arithmetic on the 85 mm bore: 95.6 kN C divided by the 32.5 mm radial section height gives 2.9 kN per section millimetre; the 1850 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. The 3.25 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 95.6/83 kN ratings and 1850 g mass this execution carries about 1.12 kN of C per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 5,300 r/min against a 5,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.06. 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

• Fillet radii must clear the chamfer so the 28 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• Preload the set against a calculated stand-off dimension — the ground faces of BEP 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 BEP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• 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.
• The steep 40° angle of 7217-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 7217 BEP as the single basic pa66 execution; the other order numbers of the 7217 size are different products and may carry different ratings — always quote the full designation when purchasing.
