How the 7312-BECBPH model number is decoded

7312 BECBPH is SKF's 60 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 60×130×31 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. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. 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. BECBPH combines CB universal clearance with a PEEK ball-centred cage for hot, high-speed positions where PA66 is unsuitable. Envelope 60×130×31 mm (2.362×5.118×1.22 in), 35.0 mm radial section height, C 104 kN, C0 76.5 kN, Pu 3.2 kN.reference speed 6,300 r/min (thermal) and limiting speed 6,700 r/min (mechanical), catalogue mass 1750 g. Sizing arithmetic on the 60 mm bore: 104 kN C divided by the 35.0 mm radial section height gives 3.0 kN per section millimetre; the 1750 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Envelope economics: the 31 mm width over a 35.0 mm section yields 0.89 mm of ring width per section millimetre, and the bearing weighs 1750 g for 104 kN of dynamic capacity — about 17 g per rated kN. Speed-ratio note for this exact unit: the reference speed is 6,300 r/min against a 6,700 r/min limiting speed, i.e. a reference-to-limit ratio of 0.94. PEEK cage note: the PH cage is moulded from glass-fibre reinforced polyetheretherketone, ball-centred, aimed at high-speed oil-air and grease positions where PA66 would approach its thermal and speed limits; it needs clean lubricant (PEEK cages are sensitive to hard-particle cage-wear) and is a separate order number from the brass BECBM.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 60 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.
• Greased positions should fill roughly 25–35 % of the free volume on a 7312-BECBPH of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Assign interference to the rotating ring — roughly k5 on a 60 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• Fillet radii must clear the chamfer so the 31 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• The steep 40° angle of 7312-BECBPH 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 BECBPH 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.
