204RY2 Agri Bearing for International Harvester – High-Load


Field Notes and Specs: 204RY2 agri bearing for IH machines

If you wrench on planters or older combines, you’ve almost certainly handled the 204RY2 Agri Bearing For International Harvester. Built in Hebei’s bearing corridor—Origin: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province—it’s a tough little unit that, in practice, tends to outlast bargain-bin replacements. To be honest, most of the buzz I hear from mechanics is about seal performance and grease life, not glossy packaging.

204RY2 Agri Bearing for International Harvester – High-Load

What it is (and where it fits)

The 204RY2 Agri Bearing For International Harvester is a chrome-steel, double-sealed agricultural radial bearing commonly used in planter row units, gauge/press wheels, and certain IH header applications. RY2 typically denotes dual contact seals—more drag than shielded, but far better dust exclusion in tilled soils. In fact, many customers say that in no-till corn with abrasive residue, these seals pay for themselves by mid-season.

Typical technical specifications

ParameterSpec (≈ typical; confirm drawing)
MaterialChrome steel (GCr15/100Cr6 per ASTM A295); hardened raceways
Bore / OD / Width≈20 mm / ≈47 mm / ≈14–16 mm (application-specific)
SealsRY2 double-lip nitrile (contact) with debris guard
Internal ClearanceC3 (agriculture duty)
GreaseNLGI 2 lithium-complex EP, ≈25–35% fill
Dynamic/Static Rating≈19–22 kN / ≈10–12 kN (real-world use may vary)
Operating Temp-20°C to +110°C continuous (short peaks higher)
CertificationsFactory ISO 9001; RoHS/REACH compliant grease

Process flow and testing (why this matters)

Materials enter with heat/chem checks; races are turned, then heat-treated to ≈60–64 HRC, precision-ground, and paired with pressed-steel cages. Seals are molded to a dual-lip profile; grease is metered by volume. End-of-line: 100% noise/vibration scan, seal drag torque sampling, and rotating torque. Dimensional checks to ISO 492; life calculations per ISO 281; occasional salt-fog (ASTM B117) on exterior components. In our notes, lab dust-ingress tests showed

Applications and service life

  • IH planters: gauge/press wheel hubs, some opener disc hubs.
  • Headers and auger idlers on select models.
  • Tillage attachments that see shock + mud spray.

Field life? It varies. On mellow soils, I’ve seen the 204RY2 Agri Bearing For International Harvester run 3–5 seasons; in sandy, high-residue corn, 2–3 is more typical. Preventative washing (low pressure) and off-season grease audit extend life noticeably.

Customization

Options include square/hex/round bores, special greases (food-grade, low-temp), laser marking, and kitted hubs. For harsh silt, I’d spec a higher fill EP grease and a slightly stiffer seal lip—yes, a touch more drag, but uptime wins.

Quick case notes

One Midwest co‑op swapped 40 row-units to the 204RY2 Agri Bearing For International Harvester; reported downtime dropped ≈30% over two springs. Across 120 bearings, return rate was about 1.5%—mostly handling damage, not functional failure. Not a lab trial, but it tracks with what I see in the field.

Bottom line: solid chrome-steel races, honest seals, and sane grease choices. Not flashy—just reliable where mud meets metal.
