How the 7214-BECBM model number is decoded

7214 BECBM is SKF's 70 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 70×125×24 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 70×125×24 mm (2.756×4.921×0.945 in), 27.5 mm radial section height, C 72 kN, C0 60 kN, Pu 2.55 kN.reference speed 6,300 r/min (thermal) and limiting speed 8,000 r/min (mechanical), catalogue mass 1100 g. Sizing arithmetic on the 70 mm bore: 72 kN C divided by the 27.5 mm radial section height gives 2.6 kN per section millimetre; the 1100 g mass and 4 % Pu/C share frame the light-load floor for the adjusted-life check. Mass and section check: 1100 g inside the 70×125×24 mm outline leaves a 27.5 mm radial section, and the 60 kN static rating is 0.83× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Bore-to-OD planning: OD 125 over bore 70 is a 1.79× step for this size, and the 24 mm width gives a bore/width ratio of 2.92; use these ratios when housing space around the 70 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

• Fillet radii must clear the chamfer so the 24 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 BECBM unit is ground for arbitrary pairing, a basic execution is not.
• Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
• Greased positions should fill roughly 25–35 % of the free volume on a 7214-BECBM of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• The steep 40° angle of 7214-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.
