How the 7319-BECBM model number is decoded

7319 BECBM 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. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. Envelope 95×200×45 mm (3.74×7.874×1.772 in), 52.5 mm radial section height, C 180 kN, C0 163 kN, Pu 5.7 kN.reference speed 4,000 r/min (thermal) and limiting speed 5,300 r/min (mechanical), catalogue mass 6050 g. Sizing arithmetic on the 95 mm bore: 180 kN C divided by the 52.5 mm radial section height gives 3.4 kN per section millimetre; the 6050 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Mass and section check: 6050 g inside the 95×200×45 mm outline leaves a 52.5 mm radial section, and the 163 kN static rating is 0.91× 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. Cage detail specific to this order number: the M cage is a one-piece machined brass window cage centred on the balls, chosen for high speeds, thin-film lubrication and shock loads; it is heavier and stiffer than the stamped Y-cage execution and tolerates interrupted oil supply far better than the PA66 or PEEK alternatives. Do not substitute the stamped-brass BECBY order number expecting identical cage behaviour.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• Preload the set against a calculated stand-off dimension — the ground faces of BECBM 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 45 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• Assign interference to the rotating ring — roughly k5 on a 95 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• The steep 40° angle of 7319-BECBM 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.
• Universally matchable BECBM bearings arrive ready for set mounting, not preloaded sets: preload results from how the set is clamped, so follow the SKF stand-off-ring and nut-torque procedure.
