AA35741 - John Deere Equipment Ball Bearing | OEM-Quality


Field-Tested Review: AA35741 - John Deere Equipment Ball Bearing

If you work around harvesters or hay equipment long enough, you get a sixth sense for bearings. To be honest, the AA35741 - John Deere Equipment Ball Bearing is one I keep seeing in dealer bins and farm shops because it does the simple thing right: it stays sealed, stays quiet, and doesn’t complain when the dust storms roll in.

What it is and where it’s made

Designation: SINGLE – John Deere Original Equipment Ball Bearing, noted as “BEARING, INTEGRAL S.” Origin: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province. In practice, that plant has been supplying ag-grade bearings for years; many customers say consistency has improved lately—likely tighter incoming steel checks and better grease metering.

How it’s built (materials and methods)

  • Rings/Balls: Through-hardened high-carbon chromium steel (SAE 52100 / GCr15) with vacuum-degassed cleanliness.
  • Cage: Stamped steel; riveted, optimized pocket geometry for mixed-load duty.
  • Seals: Integral contact seal both sides (common ag spec) aimed at mud/dust exclusion; low-drag lip.
  • Grease: NLGI 2 lithium complex, EP-additive package; real-world use may vary with temperature cycles.
  • Finish: Superfinished raceways to reduce micro-pitting under oscillatory motion common on headers.

Specifications (typical OEM-matched, check exact fit)

Part AA35741 - John Deere Equipment Ball Bearing
Dimensional class ISO 492 Normal (≈ABEC 1); P6 available on request
Sealing Integral contact seals, both sides (2RS-type behavior)
Dynamic load rating (C) ≈ 12–18 kN for comparable ag bearings; per ISO 281, model-dependent
Operating temp -30°C to +110°C typical for grease; short peaks higher
Service life L10 up to 10,000+ hrs in moderate load/speed; application dependent
Certifications Factory ISO 9001; material heat certs traceable

Testing and standards

Lab checks I’ve seen referenced include ISO 281 life calculations, ISO 76 static ratings, and salt-dust ingress screens approximating IP5x behavior for sealed bearings. A recent batch test showed ≤ 0.5 g dust ingress after 24 h chamber run—respectable, though, actually, field grime can be nastier. Noise/vibration per ISO 15242 landed in the “G-P0” band on average.

Applications and advantages

  • Combines and headers: oscillating loads, shaft misalignment; the seal holds up.
  • Balers, mowers, planters: medium speed, high contamination, frequent washdowns.
  • Advantages: sealed-for-life convenience, solid radial capacity, low start torque, easy drop-in replacement for AA35741 - John Deere Equipment Ball Bearing positions.

Vendor snapshot and buying notes

Vendor Warranty Seal/Grease Certs Notes
OEM (John Deere) Dealer policy Integral seals; JD-specified grease OEM QC; ISO 9001 at supplier Exact fit; premium pricing
BTZ Bearing (AA35741) Typically 12 months 2RS-style; NLGI 2 EP ISO 9001; batch traceability OEM-equivalent spec; competitive lead times
Generic import Varies Mixed sealing Varies Check noise class and seal lip design carefully

Customization

For fleets, the factory can usually tune grease type (food-grade, high-temp), seal lip materials, and packaging. I guess that matters if you’re running hot bearings on a chopper in July.

Real-world case

A Midwest contractor swapped eight positions to AA35741 - John Deere Equipment Ball Bearing equivalents before wheat. After 300 engine hours, vibration dropped ~12% on his handheld meter, and he reported less heat at the guards—small win, but it saved a Saturday.

Customer feedback (anecdotal): “Quieter than the old open-style units; seals don’t spit grease after washdown.” Your mileage will vary with alignment and torqueing, obviously.
