Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 62200-2RS | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 10×30×14 mm envelope as SKF 62200-2RS1, but catalogue C/C0 differ (9.23/5.2 kN vs 5.07/2.36 kN) — envelope match only after a load check. |

How the 4200-ATN9 model number is decoded
4200 ATN9 is a double-row deep-groove ball bearing in the 4200-series: bore code 00 follows the 10/12/15/17 mm exception table, so 4200 fits a 10 mm shaft. Two complete ball sets share the 10×30×14 mm (0.394×1.181×0.551 in) envelope, giving C 9.23 kN, C0 5.2 kN and Pu 0.224 kN, with reversing axial capacity a single-row bearing cannot match. ATN9 is the glass-fibre PA66 cage. Limiting speed 22000 r/min, mass 49 g. The arrangement is open and requires external sealing.
Typical equipment & failure modes
Common applications
- belt take-up and tensioner units
- machine tool feed drives
- lifting and hoisting gear
- fans with axial thrust reversals
Known failure patterns
- uneven load sharing between the two raceways when one ring is tilted
- polyamide cage embrittlement after sustained high-temperature service
- cage damage from running beyond the limiting speed
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- C 9.23 kN in a 14 mm width is the strength of the double-row design; use it for combined or reversing axial loads rather than pure radial duty where a slimmer single-row bearing would run cooler.
- Fit both rings square on the shoulders: the narrow internal land between the two raceways of 4200-ATN9 is sensitive to cocking during pressing.
- The ATN9 cage is glass-fibre-reinforced polyamide 66: it is light and quiet but caps continuous service around 100–120 °C in oil/grease — above that use the pressed-steel or machined-cage version of the 10 mm position.
- Two deep-groove raceways in 4200-ATN9 share the load but need parallel seats; tilting the 14 mm-wide assembly loads one row heavily and can spall it early.
- Fit both rings square on the shoulders: the narrow internal land between the two raceways of 4200-ATN9 is sensitive to cocking during pressing.
- Do not preload 4200-ATN9 to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
Frequently asked questions
What are the dimensions of 4200-ATN9?
Double-row 4200 ATN9 measures 10×30×14 mm (0.394×1.181×0.551 in), about 49 g.
What does ATN9 mean on 4200 ATN9?
A = double-row deep-groove arrangement, TN9 is a glass-fibre-reinforced polyamide 66 cage; it limits continuous temperature to roughly 100–120 °C.
Is 4200-ATN9 interchangeable with a 62-series single-row bearing?
No: although bore matches, OD and width differ and the seat shoulders must suit the wide double-row ring; 10×30×14 mm is its own envelope.
Does 4200-ATN9 run as fast as a single-row bearing?
Somewhat slower: SKF rates it to 22000 r/min; the two cages and wider grease volume generate more drag than a single-row 6200.
