How the 7302-BE-2RZP model number is decoded

7302 BE-2RZP is SKF's 15 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 15×42×13 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 15×42×13 mm (0.591×1.654×0.512 in), 13.5 mm radial section height, C 13 kN, C0 6.7 kN, Pu 0.28 kN.reference speed 22,000 r/min (thermal) and limiting speed 17,000 r/min (mechanical), catalogue mass 82 g. Envelope economics: the 13 mm width over a 13.5 mm section yields 0.96 mm of ring width per section millimetre, and the bearing weighs 82 g for 13 kN of dynamic capacity — about 6 g per rated kN. Mass and section check: 82 g inside the 15×42×13 mm outline leaves a 13.5 mm radial section, and the 6.7 kN static rating is 0.52× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Speed-ratio note for this exact unit: the reference speed is 22,000 r/min against a 17,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.29. 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

• Preload the set against a calculated stand-off dimension — the ground faces of BE-2RZP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• At 15 mm bore the j5 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.
• 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.
• Mount by induction-heating the inner ring to max 120 °C — the PA66 cage sets the ceiling, not the steel; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• The steep 40° angle of 7302-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 7302-BE-2RZP add little drag but are not contact seals; in wet or fine-dust duty retain external sealing at the housing.
