How the 7314 model number is decoded

Ordering number 7314 BEP in the SKF Rolling Bearings catalogue denotes a single-row 40° angular-contact ball bearing for a 70 mm shaft, medium (7300) series, with an open PA66-caged execution and one-direction axial capacity.Digit by digit, 7314 reads as bearing type 7 (single-row angular contact), medium section diameter series 3, and bore reference 14 resolving to 70 mm; 150 mm OD and 35 width are the matching ISO 15 boundary values. The letters mean B = 40° angle, E = enhanced ball complement and race geometry, P = PA66 glass-fibre cage, so this 7314 is the open polymer-caged execution rather than the sealed or brass-cage catalogue variants. The 3.65 kN Pu figure feeds the SKF adjusted-life equation at contaminated or partial-film conditions, and the 0.76 C0/C balance shows this execution is tuned to thrust-heavy combined loads rather than pure radial running. Because the contact line runs at 40°, one 7314 reacts thrust in a single direction; bidirectional shafts need a DB or DF pair with defined preload, and a rotating inner ring on a 70 mm shaft typically takes a k5 seat with an H7 housing bore.

Typical equipment & failure modes

Common applications

  • agricultural and construction machinery drives
  • vibrating screens and shale shaker shafts
  • medium and large machine-tool spindles
  • industrial gearboxes and speed reducers

Known failure patterns

  • contamination wear through the open arrangement when no external seal is provided
  • raceway smearing under marginal lubrication at start-up before oil reaches the contact ellipse
  • fretting at the ground set faces of a pair whose clamp torque relaxes in service
  • thermal preload runaway in a back-to-back pair when inner-ring heat has nowhere to expand
  • cage pocket damage when the bearing is started cold with grease of too-high base-oil viscosity
  • mounting score marks when the bearing is cocked over the shaft keyway or a burr

Selection pitfalls — read before you substitute

  • Mount the 70 mm bore 7314 by induction heating of the inner ring (max 120 °C — the PA66 cage sets the ceiling, not the steel); driving it home through the outer ring or balls brinells the asymmetric raceway.
  • The 73xx medium section at 70 mm bore (150×35 mm) is heavier-rated than the 7214 but runs hotter at the same speed; do not substitute a 7314 into a 72-series spindle position without re-checking dn, lubricant film and preload.
  • The 40° contact angle creates an induced axial load under pure radial force; include it in the 7314 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its balls.
  • A single 7314 cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use a DB or DF matched pair for bidirectional location.
  • The PA66 cage is rated for 120 °C continuous service; sustained hotter running (hot process gas, heat soak from a coupling) embrittles the cage — select the machined-brass BECBM execution for positions above that.
  • The 119/90 kN ratings are SKF catalogue 17000 values for the 7314 BEP execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification and re-verify for critical drives.
  • SKF lists several executions of 7314 (BEP basic, BECBP universally matchable, BE-2RZP sealed, BECBM brass-cage, ACC-series at 25°); they are not interchangeable order numbers — quote the full 7314 BEP designation when purchasing and match the execution to the mounting arrangement.
  • A plain 7314 BEP is a single open bearing, not a universally matchable one; to mount a defined DB/DF pair order the BECBP (CB) execution — pairing two unmatched basic units gives uncontrolled preload because the side faces are not ground for set mounting.

Frequently asked questions

What are the dimensions and catalogue data of SKF 7314?

The SKF 7314 BEP is a single-row angular-contact ball bearing with 70 mm bore, 150 mm outer diameter and 35 mm width (2.756 × 5.906 × 1.378 in) per ISO 15. From SKF catalogue 17000: basic dynamic load rating C 119 kN, C0 90 kN, fatigue load limit Pu 3.65 kN, reference speed 5,600 r/min, limiting speed 5,300 r/min, mass about 2650 g. It is an open 40° contact-angle bearing with a PA66 cage. Preload and lubricant film move the real thermal limit, so treat 5,600 r/min as catalogue conditions, not a guarantee in the housing.

How does the 7314 bore code work?

The last two digits of 7314 are bore code 14, so 14 × 5 = 70 mm bore. The 150 mm OD and 35 mm width come from the ISO 15 diameter-series plan, shared with the 6314 deep-groove envelope.

What do the 73xx and BEP designations mean?

The leading 7 marks a single-row angular-contact bearing; the second digit 3 is the ISO diameter series (medium section). In the SKF suffix, B denotes the 40° contact angle, E the enhanced internal design, P the glass-fibre PA66 cage. The plain BEP is the basic open single bearing; BECBP is the universally matchable version. A 25° variant (suffix A, e.g. ACC) runs faster but carries less thrust.

Can a single 7314 take axial load in both directions?

No — one single-row angular-contact bearing reacts thrust in one direction only, and under radial load its 40° contact angle induces an axial force. Use two bearings as a matched pair: DB (back-to-back) for a rigid, moment-resisting arrangement, DF (face-to-face) where thermal expansion must be tolerated, or DT (tandem) where one-direction thrust is shared. Preload light/medium choice changes stiffness and heat, so calculate it from the load diagram rather than torquing until the pair feels tight.

How does 7314 compare with a deep-groove 6314?

Both use the 70×150×35 mm ISO 15 envelope, but the angular-contact 7314 has an asymmetric raceway at a nominal 40° angle: higher combined axial-plus-radial capacity and controlled preload, at the cost of speed, one-direction thrust, mandatory pairing for reversing loads and a minimum axial load requirement. Envelope interchange is therefore dimensional only; the application must actually present axial load for the 7314 design to perform.
