How the 7320-BEM model number is decoded

7320 BEM is SKF's 100 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 100×215×47 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. machined brass cage, ball-centred (suffix M), the choice for high speed, marginal lubrication and shock duty. The BEM is a basic single bearing with a machined brass cage — not ground for universal matching; use the BCBM or BECBM execution when defined DB/DF sets are required.. Envelope 100×215×47 mm (3.937×8.465×1.85 in), 57.5 mm radial section height, C 203 kN, C0 190 kN, Pu 6.4 kN.reference speed 3,800 r/min (thermal) and limiting speed 3,600 r/min (mechanical), catalogue mass 7500 g. Load balance: C0 190 kN against C 203 kN gives a 0.94 ratio, typical of a steep-angle axial-oriented design; Pu 6.4 kN enters the SKF adjusted-life equation rather than the basic rating life. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 3,600 r/min while thermal balance under catalogue load sets the 3,800 r/min reference; at dm ≈ 157.5 mm the corresponding dn is approximately 567k mm·r/min. Speed-ratio note for this exact unit: the reference speed is 3,800 r/min against a 3,600 r/min limiting speed, i.e. a reference-to-limit ratio of 1.06. Ordering note: BEM pairs the optimized 40-degree geometry with a machined one-piece brass window cage as a basic (non-universal) single bearing; it is the brass-cage counterpart of the polymer BEP, and universally matchable positions must use the BECBM or BCBM execution instead.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Preload the set against a calculated stand-off dimension — the ground faces of BEM 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 BEM establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• Fillet radii must clear the chamfer so the 47 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• Do not mix execution classes inside one set: a universally matchable BEM unit is ground for arbitrary pairing, a basic execution is not.
• The steep 40° angle of 7320-BEM 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 7320 BEM as the single basic machined brass execution; the other order numbers of the 7320 size are different products and may carry different ratings — always quote the full designation when purchasing.
