How the 7202 model number is decoded
In the 7200-series (ISO 15 diameter series 2) the last two digits encode the bore: 7202 carries bore code 02 = 15 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 35 mm and width 11 mm come from the ISO 15 boundary-dimensions general plan, shared with the 6202 deep-groove envelope. The '7' prefix marks a single-row angular-contact design with an asymmetric raceway and a nominal 40° contact angle (suffix C); a higher-angle variant carries more axial load, a 25° (E / A5) variant runs faster. For combined radial and axial load with a rotating inner ring on a 15 mm shaft, specify a j5 shaft seat with an H7 housing bore — verify against the load direction and magnitude, and pair two units (DB or DF) for bidirectional thrust.
Typical equipment & failure modes
Common applications
- fans and blowers
- hand tool rotors
- small precision gearboxes
- instrument spindles
Known failure patterns
- false brinelling from vibration while the shaft is stationary
- edge loading and early spalling from shaft deflection or housing misalignment
- electric pitting in VFD-driven spindles without shaft grounding protection
- raceway spalling from axial overload exceeding the single-direction thrust rating
Selection pitfalls — read before you substitute
- Bore codes 00–03 use the exception table: 7202 fits a 15 mm shaft — the code × 5 mnemonic does not apply below code 04.
- The 72xx light section at 15 mm bore is the default general-purpose angular-contact envelope (35×11 mm); the deep-groove counterpart 6202 shares the envelope but is not a drop-in swap for combined-load duty.
- Preload class matters: a 7202 in a DB pair is supplied as preload class light (L) for speed or heavy (H) for rigidity; mixing unmarked bearings in a pair gives uneven preload and short life.
- Mounting direction is fixed by the asymmetric raceway — the marked side faces the axial load; installing 7202 backwards loads the low shoulder and displaces the balls out of the raceway.
Frequently asked questions
What are the dimensions of a 7202 angular-contact bearing?
A 7202 single-row angular-contact ball bearing has a 15 mm bore, 35 mm outer diameter and 11 mm width (0.591 × 1.378 × 0.433 in), per ISO 15 boundary dimensions. It is an open bearing with a nominal 40° contact angle. Geometry-based estimated mass is about 44 g for a brass-cage unit; catalogue masses vary with cage and ball complement.
Why does 7202 not follow the bore-code × 5 rule?
Codes 00–03 use the exception table (10, 12, 15 and 17 mm): 7202 with code 02 has a 15 mm bore. The code × 5 convention starts at code 04 (20 mm).
What is the contact angle of 7202?
The nominal contact angle is 40° (suffix C): a higher angle carries more axial load but limits speed. A 25° (suffix E or A5) variant runs faster and is preferred for high-speed spindles; a 15° (suffix C7) version exists for very-high-speed duty. Confirm the angle and ball complement in the supplier catalogue.
Can a single 7202 take axial load in both directions?
No. A single-row angular-contact bearing carries axial load in one direction only. For bidirectional thrust, mount a matched pair — DB (back-to-back) for a rigid, moment-resisting arrangement with preload class light (L) for speed or heavy (H) for stiffness, DF (face-to-face) for thermal expansion tolerance, or DT (tandem) to share one-direction load.
How does 7202 compare with a deep-groove 6202?
Both share the 15×35×11 mm ISO 15 envelope (10.0 mm radial section), but the angular-contact 7202 has an asymmetric raceway and 40° contact angle: it carries higher combined axial+radial load and runs with controlled preload, but is slower, noisier and needs pairing — it is not a drop-in replacement for a deep-groove 6202.
