How the 7313-BECBPH model number is decoded

7313 BECBPH is SKF's 65 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 65×140×33 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 65×140×33 mm (2.559×5.512×1.299 in), 37.5 mm radial section height, C 116 kN, C0 86.5 kN, Pu 3.65 kN.reference speed 6,000 r/min (thermal) and limiting speed 6,300 r/min (mechanical), catalogue mass 2150 g. At the printed limiting speed of 6,300 r/min the mean pitch diameter dm ≈ 102.5 mm implies a dn value around 646k mm·r/min; the 6,000 r/min reference speed is the thermal-planning figure under catalogue load. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 6,300 r/min while thermal balance under catalogue load sets the 6,000 r/min reference; at dm ≈ 102.5 mm the corresponding dn is approximately 646k mm·r/min. Speed-ratio note for this exact unit: the reference speed is 6,000 r/min against a 6,300 r/min limiting speed, i.e. a reference-to-limit ratio of 0.95. 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

• 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.
• Greased positions should fill roughly 25–35 % of the free volume on a 7313-BECBPH of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Greased positions should fill roughly 25–35 % of the free volume on a 7313-BECBPH of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Reference and limiting speeds are different ceilings: design to both, and remember preload and oil/air cooling move the real thermal limit far from the catalogue reference value.
• The steep 40° angle of 7313-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.
