How the 7204-BE-2RZP model number is decoded

7204 BE-2RZP is SKF's 20 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 20×47×14 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. -2RZ marks non-contact NBR seals on both sides riding in recessed grooves: they keep contamination and the standard grease fill in without lip drag, and P again denotes the PA66 cage. Envelope 20×47×14 mm (0.787×1.85×0.551 in), 13.5 mm radial section height, C 13.3 kN, C0 7.65 kN, Pu 0.325 kN.reference speed 19,000 r/min (thermal) and limiting speed 14,000 r/min (mechanical), catalogue mass 150 g. The 0.325 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 13.3/7.65 kN ratings and 150 g mass this execution carries about 0.67 kN of C per millimetre of bore. Sizing arithmetic on the 20 mm bore: 13.3 kN C divided by the 13.5 mm radial section height gives 1.0 kN per section millimetre; the 150 g mass and 2 % Pu/C share frame the light-load floor for the adjusted-life check. Bore-to-OD planning: OD 47 over bore 20 is a 2.35× step for this size, and the 14 mm width gives a bore/width ratio of 1.43; use these ratios when housing space around the 20 mm shaft is the first constraint. Sealing note: the two non-contact NBR -2RZ seals run in recessed grooves without touching the inner ring, so drag and speed loss stay small while the standard grease fill is retained and coarse dust is excluded; they are not lip-contact seals, so pressure washing and fine slurry still require external housing seals. The uncapped BECBP/BEP executions are the open counterparts.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Do not mix execution classes inside one set: a universally matchable BE-2RZP unit is ground for arbitrary pairing, a basic execution is not.
• Fillet radii must clear the chamfer so the 14 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• Assign interference to the rotating ring — roughly k5 on a 20 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
• Greased positions should fill roughly 25–35 % of the free volume on a 7204-BE-2RZP 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 7204-BE-2RZP 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.
• The non-contact -2RZ seals of 7204-BE-2RZP add little drag but are not contact seals; in wet or fine-dust duty retain external sealing at the housing.
