How the 7302-BECBP model number is decoded

7302 BECBP is SKF's 15 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 15×42×13 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 15×42×13 mm (0.591×1.654×0.512 in), 13.5 mm radial section height, C 13 kN, C0 6.7 kN, Pu 0.28 kN.reference speed 22,000 r/min (thermal) and limiting speed 20,000 r/min (mechanical), catalogue mass 80 g. Selection figures for 7302 BECBP: the static-to-dynamic ratio C0/C is 0.52, Pu 0.28 kN is about 2 % of C, and catalogue mass works out to roughly 5 g per millimetre of bore. At the printed limiting speed of 20,000 r/min the mean pitch diameter dm ≈ 28.5 mm implies a dn value around 570k mm·r/min; the 22,000 r/min reference speed is the thermal-planning figure under catalogue load. Speed-ratio note for this exact unit: the reference speed is 22,000 r/min against a 20,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.10. 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

  • dental and laboratory high-speed rotors
  • miniature turbine and gyro drives
  • high-speed engraving and routing spindles

Known failure patterns

  • false brinelling on idle paired sets exposed to machine vibration
  • contact-angle shift and edge loading after uneven locknut torque tilts the set
  • ball skidding when Fa/Fr stays below the 1,0 (40°) or 0,55 (25°) ratio and the contact ellipse is unloaded
  • PA66 cage embrittlement inside a preloaded set where heat accumulates faster than in a single mounting
  • brinelling from pressing the ring home through the balls or from static overload
  • mounting score marks when the bearing is cocked over a burr or keyway

Selection pitfalls — read before you substitute

  • 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.
  • 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.
  • 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.
  • 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 7302-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 7302-BECBP?

7302 BECBP measures 15 mm bore × 42 mm OD × 13 mm width (0.591 × 1.654 × 0.512 in), mass about 80 g. SKF 17000 ratings: C 13 kN, C0 6.7 kN, Pu 0.28 kN, reference speed 22,000 r/min (thermal) and limiting speed 20,000 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.

Which fits should I use for 7302-BECBP?

With a rotating inner ring use roughly j5 on the 15 mm shaft and H7 in the housing; give the stationary ring a slide fit for axial setting, and reverse the logic when the outer ring rotates.

Which grease and fill for 7302-BECBP?

A premium mineral-oil grease with polyurea or lithium complex thickener and NLGI 2 consistency suits normal operating temperature; fill roughly 25–35 % of the free volume, and stay within the — the PA66 cage sets the ceiling, not the steel. Oil-air or oil-jet lubrication is the choice near the 20,000 r/min ceiling.
