How the 7319-BECBP model number is decoded
7319 BECBP is SKF's 95 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 95×200×45 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 95×200×45 mm (3.74×7.874×1.772 in), 52.5 mm radial section height, C 180 kN, C0 163 kN, Pu 5.7 kN.reference speed 4,000 r/min (thermal) and limiting speed 4,300 r/min (mechanical), catalogue mass 6050 g. Selection figures for 7319 BECBP: the static-to-dynamic ratio C0/C is 0.91, Pu 5.7 kN is about 3 % of C, and catalogue mass works out to roughly 64 g per millimetre of bore. At the printed limiting speed of 4,300 r/min the mean pitch diameter dm ≈ 147.5 mm implies a dn value around 634k mm·r/min; the 4,000 r/min reference speed is the thermal-planning figure under catalogue load. Bore-to-OD planning: OD 200 over bore 95 is a 2.11× step for this size, and the 45 mm width gives a bore/width ratio of 2.11; use these ratios when housing space around the 95 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
- process pump and compressor drives
- printing and paper-machine rolls
- crane sheave and hoist gearboxes
Known failure patterns
- preload loss as a loosely clamped set runs slack and the balls smear the raceways
- thermal preload runaway in a back-to-back pair when inner-ring heat cannot expand away
- 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
- edge loading from shaft deflection or housing misalignment
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.
- Greased positions should fill roughly 25–35 % of the free volume on a 7319-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- Mount by induction-heating the inner ring to max 120 °C — the PA66 cage sets the ceiling, not the steel; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
- Greased positions should fill roughly 25–35 % of the free volume on a 7319-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- The steep 40° angle of 7319-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 7319-BECBP?
7319 BECBP measures 95 mm bore × 200 mm OD × 45 mm width (3.74 × 7.874 × 1.772 in), mass about 6050 g. SKF 17000 ratings: C 180 kN, C0 163 kN, Pu 5.7 kN, reference speed 4,000 r/min (thermal) and limiting speed 4,300 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.
What do the reference and limiting speeds mean for 7319-BECBP?
The 4,000 r/min reference (thermal) and 4,300 r/min limiting (mechanical) speeds are catalogue conditions; preload, lubrication and heat removal move the permissible value, so re-calculate for the actual arrangement.
Can one 7319-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.
