How the 7201-BECBP model number is decoded
7201 BECBP is SKF's 12 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 12×32×10 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 12×32×10 mm (0.472×1.26×0.394 in), 10.0 mm radial section height, C 7.61 kN, C0 3.8 kN, Pu 0.16 kN.reference speed 28,000 r/min (thermal) and limiting speed 26,000 r/min (mechanical), catalogue mass 36 g. At the printed limiting speed of 26,000 r/min the mean pitch diameter dm ≈ 22.0 mm implies a dn value around 572k mm·r/min; the 28,000 r/min reference speed is the thermal-planning figure under catalogue load. Envelope economics: the 10 mm width over a 10.0 mm section yields 1.00 mm of ring width per section millimetre, and the bearing weighs 36 g for 7.61 kN of dynamic capacity — about 5 g per rated kN. Bore-to-OD planning: OD 32 over bore 12 is a 2.67× step for this size, and the 10 mm width gives a bore/width ratio of 1.20; use these ratios when housing space around the 12 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
- high-speed engraving and routing spindles
- small machine-tool spindles and high-speed heads
- servo and stepper motor shafts
Known failure patterns
- raceway spalling from axial overload beyond the single-direction thrust rating
- ball skidding when the induced axial load unloads the inactive bearing of a pair
- 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
- edge loading from shaft deflection or housing misalignment
- brinelling from pressing the ring home through the balls or from static overload
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.
- Fillet radii must clear the chamfer so the 10 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- 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.
- Fillet radii must clear the chamfer so the 10 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- The steep 40° angle of 7201-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 7201-BECBP?
7201 BECBP measures 12 mm bore × 32 mm OD × 10 mm width (0.472 × 1.26 × 0.394 in), mass about 36 g. SKF 17000 ratings: C 7.61 kN, C0 3.8 kN, Pu 0.16 kN, reference speed 28,000 r/min (thermal) and limiting speed 26,000 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.
What minimum axial load does 7201-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.
What is the difference between BEP, BECBP and BECBM?
All share the 40° optimized geometry: BEP is the basic PA66-caged single bearing, BECBP adds CB universal matching (ground faces, Normal clearance) with the same PA66 cage, and BECBM is the universally matchable version with a machined brass cage for higher speed and temperature.
