How the 7319-BEM model number is decoded

7319 BEM is SKF's 95 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 95×200×45 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 95×200×45 mm (3.74×7.874×1.772 in), 52.5 mm radial section height, C 168 kN, C0 150 kN, Pu 5.2 kN.reference speed 4,000 r/min (thermal) and limiting speed 4,000 r/min (mechanical), which coincide for this size, catalogue mass 6050 g. Load balance: C0 150 kN against C 168 kN gives a 0.89 ratio, typical of a steep-angle axial-oriented design; Pu 5.2 kN enters the SKF adjusted-life equation rather than the basic rating life. Mass and section check: 6050 g inside the 95×200×45 mm outline leaves a 52.5 mm radial section, and the 150 kN static rating is 0.89× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Bore-to-OD planning: OD 200 over bore 95 is a 2.11× step for this size, and the 45 mm width gives a bore/width ratio of 2.11; use these ratios when housing space around the 95 mm shaft is the first constraint. 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

• One 7319-BEM 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.
• Fillet radii must clear the chamfer so the 45 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• 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 7319-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 7319 BEM as the single basic machined brass execution; the other order numbers of the 7319 size are different products and may carry different ratings — always quote the full designation when purchasing.
