How the 7322 model number is decoded

7322 is SKF's single-row angular-contact ball bearing in the medium (7300) series of the 7xxx range: an asymmetric-raceway open bearing with a nominal 40° contact angle, listed as 7322 BECBP in the SKF Rolling Bearings catalogue.Digit by digit, 7322 reads as bearing type 7 (single-row angular contact), medium section diameter series 3, and bore reference 22 resolving to 110 mm; 240 mm OD and 50 width are the matching ISO 15 boundary values. The suffix decodes as B for the 40° contact-angle execution, E for SKF's enhanced internal design with larger/fewer balls, and P for the glass-fibre reinforced PA66 ball-centred cage (continuous temperature ceiling 120 °C). CB means the side faces are ground for universal matching with Normal internal axial clearance, which is the starting point for field-set preload rather than a factory-matched fixed-preload set. The 65.0 mm radial section height ((240−110)/2) and 10000 g catalogue mass frame a 110 mm bore bearing rated at 240 kN C — roughly 2.18 kN of dynamic capacity per millimetre of bore before application factors. A single 7322 locates the shaft in one axial direction only; for bidirectional location order a matched pair — DB for moment stiffness, DF for tolerance of thermal expansion — and size the preload against the real load and speed of the position.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 110 mm bore the ring mass is high enough that cocking during mounting damages the cage and race lips; guide the ring square, confirm seat contact around the full circumference, and re-check preload after the first thermal cycle of the paired set.
• The 73xx medium section at 110 mm bore (240×50 mm) is heavier-rated than the 7222 but runs hotter at the same speed; do not substitute a 7322 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 7322 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its balls.
• Preload is a design value, not an assembly feel: excessive preload in the 7322 pair raises operating temperature and can trigger thermal runaway back-to-back, while too little lets the balls skid and smear the raceway under light load.
• Shaft and housing fillets must clear the bearing chamfer so the 50 mm-wide ring seats square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
• The 240/245 kN ratings are SKF catalogue 17000 values for the 7322 BECBP 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 7322 (BEP basic, BECBP universally matchable, BE-2RZP sealed, BECBM brass-cage, ACC-series at 25°); they are not interchangeable order numbers — quote the full 7322 BECBP designation when purchasing and match the execution to the mounting arrangement.
• The CB execution (7322 BECBP) ships prepared for pair mounting but is not a matched set by itself: preload results from how the pair is clamped, so follow the SKF stand-off-ring and nut-torque procedure rather than assuming the bearings arrive preloaded.
