How the 7314-BECBPH model number is decoded

7314 BECBPH is SKF's 70 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 70×150×35 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 70×150×35 mm (2.756×5.906×1.378 in), 40.0 mm radial section height, C 127 kN, C0 98 kN, Pu 3.9 kN.reference speed 5,600 r/min (thermal) and limiting speed 5,600 r/min (mechanical), which coincide for this size, catalogue mass 2650 g. Load balance: C0 98 kN against C 127 kN gives a 0.77 ratio, typical of a steep-angle axial-oriented design; Pu 3.9 kN enters the SKF adjusted-life equation rather than the basic rating life. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 5,600 r/min while thermal balance under catalogue load sets the 5,600 r/min reference; at dm ≈ 110.0 mm the corresponding dn is approximately 616k mm·r/min. Bore-to-OD planning: OD 150 over bore 70 is a 2.14× step for this size, and the 35 mm width gives a bore/width ratio of 2.00; use these ratios when housing space around the 70 mm shaft is the first constraint. 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

• Fillet radii must clear the chamfer so the 35 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 70 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• Assign interference to the rotating ring — roughly k5 on a 70 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• Preload the set against a calculated stand-off dimension — the ground faces of BECBPH establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• The steep 40° angle of 7314-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.
