How the 7206-BECBM model number is decoded

7206 BECBM is SKF's 30 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 30×62×16 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 30×62×16 mm (1.181×2.441×0.63 in), 16.0 mm radial section height, C 24 kN, C0 15.6 kN, Pu 0.655 kN.reference speed 13,000 r/min (thermal) and limiting speed 18,000 r/min (mechanical), catalogue mass 200 g. Envelope economics: the 16 mm width over a 16.0 mm section yields 1.00 mm of ring width per section millimetre, and the bearing weighs 200 g for 24 kN of dynamic capacity — about 8 g per rated kN. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 18,000 r/min while thermal balance under catalogue load sets the 13,000 r/min reference; at dm ≈ 46.0 mm the corresponding dn is approximately 828k mm·r/min. Speed-ratio note for this exact unit: the reference speed is 13,000 r/min against a 18,000 r/min limiting speed, i.e. a reference-to-limit ratio of 0.72. 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

• Assign interference to the rotating ring — roughly k5 on a 30 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• 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.
• Mount by induction-heating the inner ring to max 120 °C; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• Do not mix execution classes inside one set: a universally matchable BECBM unit is ground for arbitrary pairing, a basic execution is not.
• The steep 40° angle of 7206-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.
