How the 7319-BEP model number is decoded
7319 BEP 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. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units.. Envelope 95×200×45 mm (3.74×7.874×1.772 in), 52.5 mm radial section height, C 168 kN, C0 150 kN, Pu 5.2 kN.reference speed 4,000 r/min (thermal) and limiting speed 3,800 r/min (mechanical), catalogue mass 6050 g. Envelope economics: the 45 mm width over a 52.5 mm section yields 0.86 mm of ring width per section millimetre, and the bearing weighs 6050 g for 168 kN of dynamic capacity — about 36 g per rated kN. Mass and section check: 6050 g inside the 95×200×45 mm outline leaves a 52.5 mm radial section, and the 150 kN static rating is 0.89× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. 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. Basic polymer-cage execution: BEP is delivered as an individual open bearing with the 40-degree optimized internals and a glass-fibre PA66 ball-centred cage; it is not ground on the side faces for arbitrary pairing, so a reversing-thrust position should order BECBP for a set rather than mounting two unmatched BEP units.
Typical equipment & failure modes
Common applications
- industrial gearboxes and speed reducers
- process pump and compressor drives
- printing and paper-machine rolls
Known failure patterns
- fretting at the ground set faces of a universal pair whose clamp torque relaxes
- raceway spalling from axial overload beyond the single-direction thrust rating
- ball skidding when Fa/Fr stays below the 1,0 (40°) or 0,55 (25°) ratio and the contact ellipse is unloaded
- PA66 cage creep or embrittlement when the non-universal single bearing is run above 120 °C
- hard-particle indentation of the asymmetric raceway in unfiltered oil
- brinelling from pressing the ring home through the balls or from static overload
Selection pitfalls — read before you substitute
- Greased positions should fill roughly 25–35 % of the free volume on a 7319-BEP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- Assign interference to the rotating ring — roughly k5 on a 95 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
- Fillet radii must clear the chamfer so the 45 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- One 7319-BEP 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.
- The steep 40° angle of 7319-BEP 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.
- Catalogue ratings are SKF PUB BU/P1 17000 figures for 7319 BEP as the single basic pa66 execution; the other order numbers of the 7319 size are different products and may carry different ratings — always quote the full designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 7319-BEP?
7319 BEP 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 168 kN, C0 150 kN, Pu 5.2 kN, reference speed 4,000 r/min (thermal) and limiting speed 3,800 r/min (mechanical).
What does the BEP 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. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units..
What minimum axial load does 7319-BEP 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.
