How the 4213-ATN9 model number is decoded

4213 ATN9 is a double-row deep-groove ball bearing in the 4200-series: the last two digits encode the bore: 4213 carries code 13 = 65 mm (code × 5). Two complete ball sets share the 65×120×31 mm (2.559×4.724×1.22 in) envelope, giving C 67.6 kN, C0 67 kN and Pu 2.8 kN, with reversing axial capacity a single-row bearing cannot match. ATN9 is the glass-fibre PA66 cage. Limiting speed 4800 r/min, mass 1450 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 67.6 kN in a 31 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 4213-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 65 mm position.
  • Two deep-groove raceways in 4213-ATN9 share the load but need parallel seats; tilting the 31 mm-wide assembly loads one row heavily and can spall it early.
  • Two deep-groove raceways in 4213-ATN9 share the load but need parallel seats; tilting the 31 mm-wide assembly loads one row heavily and can spall it early.
  • Fillet radii must clear the 4213-ATN9 chamfer so the 31 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.

Frequently asked questions

What are the dimensions of 4213-ATN9?

Double-row 4213 ATN9 measures 65×120×31 mm (2.559×4.724×1.22 in), about 1450 g.

What does ATN9 mean on 4213 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.

What load does 4213-ATN9 carry?

C 67.6 kN, C0 67 kN and Pu 2.8 kN per catalogue 17000; both rows share the load when the rings sit parallel.

Why choose a double-row 42xx/43xx bearing?

Two ball rows give higher C (67.6 kN for 4213-ATN9), reversing axial capacity and some moment stiffness in one 31 mm-wide unit — useful on gearbox layshafts and pump shafts.
