How the 7206-BECBY model number is decoded

7206 BECBY 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. stamped brass cage, ball-centred (suffix Y) — lighter than the machined M cage but brass rather than polymer. 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. BECBY combines the optimized 40° geometry with CB universal clearance and a stamped brass Y cage. Envelope 30×62×16 mm (1.181×2.441×0.63 in), 16.0 mm radial section height, C 25.5 kN, C0 17 kN, Pu 0.71 kN.reference speed 13,000 r/min (thermal) and limiting speed 14,000 r/min (mechanical), catalogue mass 200 g. Mass and section check: 200 g inside the 30×62×16 mm outline leaves a 16.0 mm radial section, and the 17 kN static rating is 0.67× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Load balance: C0 17 kN against C 25.5 kN gives a 0.67 ratio, typical of a steep-angle axial-oriented design; Pu 0.71 kN enters the SKF adjusted-life equation rather than the basic rating life. Speed-ratio note for this exact unit: the reference speed is 13,000 r/min against a 14,000 r/min limiting speed, i.e. a reference-to-limit ratio of 0.93. Cage detail specific to this order number: the Y cage is stamped from brass strip into ball pockets rather than machined from solid, giving a lighter cage assembly and lower centrifugal mass than the M execution; it remains brass (temperature and oil-additive tolerant, unlike PA66) but is the formed-cage design, and the machined-brass BECBM order number remains the choice for severe shock or marginal lubrication.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Greased positions should fill roughly 25–35 % of the free volume on a 7206-BECBY of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Do not mix execution classes inside one set: a universally matchable BECBY unit is ground for arbitrary pairing, a basic execution is not.
• At 30 mm bore the k5 seat assumes a steel shaft and housing; aluminium housings grow faster with temperature, so re-check the outer-ring setting when the case is non-ferrous.
• 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.
• The steep 40° angle of 7206-BECBY 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 BECBY 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.
