How the 7314-BECBP model number is decoded
7314 BECBP is SKF's 70 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 70×150×35 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 70×150×35 mm (2.756×5.906×1.378 in), 40.0 mm radial section height, C 127 kN, C0 98 kN, Pu 3.9 kN.reference speed 5,600 r/min (thermal) and limiting speed 5,600 r/min (mechanical), which coincide for this size, catalogue mass 2650 g. The 3.9 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 127/98 kN ratings and 2650 g mass this execution carries about 1.81 kN of C per millimetre of bore. Load balance: C0 98 kN against C 127 kN gives a 0.77 ratio, typical of a steep-angle axial-oriented design; Pu 3.9 kN enters the SKF adjusted-life equation rather than the basic rating life. Bore-to-OD planning: OD 150 over bore 70 is a 2.14× step for this size, and the 35 mm width gives a bore/width ratio of 2.00; use these ratios when housing space around the 70 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
- dryer-cylinder pinion shafts
- medium and large machine-tool spindles
- industrial gearboxes and speed reducers
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
- 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
- raceway staining from water in the lubricant during idle periods
- raceway staining from water in the lubricant during idle periods
Selection pitfalls — read before you substitute
- Greased positions should fill roughly 25–35 % of the free volume on a 7314-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- One 7314-BECBP locates the shaft in one axial direction only; reversing-thrust positions need a DB or DF pair — or a double-row bearing — with preload set from the load diagram, never from assembly feel.
- Assign interference to the rotating ring — roughly k5 on a 70 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
- At 70 mm bore the k5 seat assumes a steel shaft and housing; aluminium housings grow faster with temperature, so re-check the outer-ring setting when the case is non-ferrous.
- The steep 40° angle of 7314-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 7314-BECBP?
7314 BECBP measures 70 mm bore × 150 mm OD × 35 mm width (2.756 × 5.906 × 1.378 in), mass about 2650 g. SKF 17000 ratings: C 127 kN, C0 98 kN, Pu 3.9 kN, reference speed 5,600 r/min (thermal) and limiting speed 5,600 r/min (mechanical), which coincide for this size.
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 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.
Which fits should I use for 7314-BECBP?
With a rotating inner ring use roughly k5 on the 70 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.
