How the 7215-BECBPH model number is decoded

7215 BECBPH is SKF's 75 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 75×130×25 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 75×130×25 mm (2.953×5.118×0.984 in), 27.5 mm radial section height, C 73.5 kN, C0 65.5 kN, Pu 2.7 kN.reference speed 6,000 r/min (thermal) and limiting speed 6,300 r/min (mechanical), catalogue mass 1200 g. Mass and section check: 1200 g inside the 75×130×25 mm outline leaves a 27.5 mm radial section, and the 65.5 kN static rating is 0.89× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. 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. Bore-to-OD planning: OD 130 over bore 75 is a 1.73× step for this size, and the 25 mm width gives a bore/width ratio of 3.00; use these ratios when housing space around the 75 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

• 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.
• Greased positions should fill roughly 25–35 % of the free volume on a 7215-BECBPH of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• Fillet radii must clear the chamfer so the 25 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
• The steep 40° angle of 7215-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.
