How the 7219-BEGAPH model number is decoded

7219 BEGAPH is SKF's 95 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 95×170×32 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 PEEK cage, ball-centred (suffix PH), keeping the polymer-cage speed advantage well above the PA66 temperature range. GA marks universal matching with light factory preload for back-to-back or face-to-face sets — stiffer than CB clearance while generating less heat than GB/GC. BEGAPH combines light-preload (GA) universal matching with a PEEK ball-centred cage. Envelope 95×170×32 mm (3.74×6.693×1.26 in), 37.5 mm radial section height, C 129 kN, C0 118 kN, Pu 4.4 kN.reference speed 4,500 r/min (thermal) and limiting speed 4,800 r/min (mechanical), catalogue mass 2700 g. Load balance: C0 118 kN against C 129 kN gives a 0.91 ratio, typical of a steep-angle axial-oriented design; Pu 4.4 kN enters the SKF adjusted-life equation rather than the basic rating life. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 4,800 r/min while thermal balance under catalogue load sets the 4,500 r/min reference; at dm ≈ 132.5 mm the corresponding dn is approximately 636k mm·r/min. Bore-to-OD planning: OD 170 over bore 95 is a 1.79× step for this size, and the 32 mm width gives a bore/width ratio of 2.97; use these ratios when housing space around the 95 mm shaft is the first constraint. Preload and cage note: BEGAPH arrives as a universally matchable unit with GA light preload already defined for back-to-back or face-to-face sets, combined with the glass-fibre PEEK ball-centred cage for high-speed duty; it replaces field preload adjustment, not the need for correct stand-off geometry.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Reference and limiting speeds are different ceilings: design to both, and remember preload and oil/air cooling move the real thermal limit far from the catalogue reference value.
• 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.
• At 95 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.
• Reference and limiting speeds are different ceilings: design to both, and remember preload and oil/air cooling move the real thermal limit far from the catalogue reference value.
• The steep 40° angle of 7219-BEGAPH 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 BEGAPH 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.
