How the 7219-BECBP model number is decoded

7219 BECBP 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 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 95×170×32 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. The 4.4 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 129/118 kN ratings and 2700 g mass this execution carries about 1.36 kN of C per millimetre of bore. 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. 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. 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

Selection pitfalls — read before you substitute

• Greased positions should fill roughly 25–35 % of the free volume on a 7219-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
• 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.
• One 7219-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.
• Fillet radii must clear the chamfer so the 32 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• The steep 40° angle of 7219-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.
