How the 7215-BECBP model number is decoded
7215 BECBP 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. 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. Sizing arithmetic on the 75 mm bore: 73.5 kN C divided by the 27.5 mm radial section height gives 2.7 kN per section millimetre; the 1200 g mass and 4 % Pu/C share frame the light-load floor for the adjusted-life check. 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. 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. Universal polymer-cage execution: BECBP is the factory-ground set-mounting version of the basic BEP — both side faces are finish-ground to a controlled stand-off so two units form DB, DF or DT arrangements without shims, while the glass-fibre PA66 ball-centred cage keeps the light, quiet running typical of the P-cage range; CB delivers Normal axial clearance before preload is applied at assembly.
Typical equipment & failure modes
Common applications
- printing and paper-machine rolls
- crane sheave and hoist gearboxes
- vibrating screens and shale shaker shafts
Known failure patterns
- contact-angle shift and edge loading after uneven locknut torque tilts the set
- fretting at the ground set faces of a universal pair whose clamp torque relaxes
- raceway smearing under minimum-axial-load starvation at light load and high speed
- PA66 cage embrittlement inside a preloaded set where heat accumulates faster than in a single mounting
- fretting corrosion on a loose rotating shaft seat
- fretting corrosion on a loose rotating shaft seat
Selection pitfalls — read before you substitute
- Greased positions should fill roughly 25–35 % of the free volume on a 7215-BECBP 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 7215-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- 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.
- Preload the set against a calculated stand-off dimension — the ground faces of BECBP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
- The steep 40° angle of 7215-BECBP 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 BECBP 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.
Frequently asked questions
What are the dimensions and catalogue data of 7215-BECBP?
7215 BECBP measures 75 mm bore × 130 mm OD × 25 mm width (2.953 × 5.118 × 0.984 in), mass about 1200 g. SKF 17000 ratings: 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).
What does the BECBP suffix mean?
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.
Can one 7215-BECBP take thrust in both directions?
No. A single-row angular-contact bearing reacts axial load in one direction; reversing thrust needs a DB/DF matched pair (use a universally matchable CB/GA execution) or a double-row bearing. Under radial load the 40° angle induces an axial force that the arrangement must balance.
What minimum axial load does 7215-BECBP need?
The balls must remain seated: SKF gives Fam ≈ A·(n·dm/1000)² and a load-ratio guideline of Fa/Fr ≥ 1 for the 40° B execution and ≥ 0,55 for the 25° AC execution. Preloaded pairs and spring loading are the usual ways of meeting it at light load and high speed.
