2026-09-22
When harvest season arrives, every hour of downtime matters. W208PP10 Round Bore Agricultural Bearings are among the most requested replacement parts for combine headers, feeder houses, and cleaning shoe assemblies, and Demy supplies them to farms and dealers across North America. This guide examines fitment, specifications, and installation considerations so you can order with confidence.
Understanding the W208PP10 Bearing
The W208PP10 Round Bore Agricultural Bearings is a round bore, relubricable agricultural bearing with a 1.5-inch bore, a 3.3465-inch outer diameter, and a 1.437-inch inner ring width. Its design follows the ASAE/ABMA dimensional standard for disc harrow and implement bearings, which is why it appears across many combine platforms.
| Specification | Value |
|---|---|
| Bore Diameter | 1.500 in (38.1 mm) |
| Outer Diameter | 3.3465 in (85 mm) |
| Inner Ring Width | 1.437 in (36.5 mm) |
| Outer Ring Width | 1.063 in (27 mm) |
| Seal Type | Triple-lip contact seal |
| Lubrication | Relubricable via grease fitting |
| Load Rating | Heavy-duty radial and moderate axial |
Compatibility with John Deere Combines
W208PP10 Round Bore Agricultural Bearings are not a factory-installed John Deere part number, but they are dimensionally interchangeable with several OEM bearings used on John Deere combine models. Compatibility depends on the housing, locking collar, and shaft diameter of the specific assembly.
| John Deere Model | Common Application | Direct Fit | Notes |
|---|---|---|---|
| 9500 / 9600 | Feeder house | Yes | Verify collar type |
| 9610 / 9650 | Cleaning shoe | Yes | Matches 1.5 in shaft |
| 9660 / 9670 | Header auger | Conditional | Check housing bore |
| 9770 / 9870 | Feeder house | Conditional | Confirm seal orientation |
| S660 / S670 | Cleaning shoe | Yes | Relubrication required |
Key Fitment Checks Before Installation
-
Confirm the shaft diameter measures exactly 1.500 inches.
-
Verify the housing bore accepts a 3.3465-inch outer diameter.
-
Check whether the original bearing uses a eccentric locking collar or set screw.
-
Inspect the grease passage alignment in the housing.
-
Confirm seal type suits the dust and chaff environment.
Demy recommends measuring the failed bearing before ordering. Minor variations between series and model years can affect fitment even when the part number appears identical.
Signs of Bearing Failure in Combines
-
Grease leaking from the seal lip
-
Audible rumbling or grinding under load
-
Excessive radial play at the shaft
-
Discoloration from overheating
-
Uneven wear on the inner ring raceway
W208PP10 Round Bore Agricultural Bearings FAQ
Q: Will W208PP10 Round Bore Agricultural Bearings fit a John Deere 9600 feeder house without modification?
A: In most cases, yes. The W208PP10 Round Bore Agricultural Bearings matches the 1.5-inch shaft and housing bore used on the 9600 feeder house, but you should confirm the locking method. If the original uses an eccentric collar, order the matching collar with the bearing. Demy provides collar options for every unit shipped.
Q: How often should W208PP10 Round Bore Agricultural Bearings be relubricated during harvest?
A: Relubricate every 50 to 100 operating hours, or daily in high-dust conditions. The W208PP10 Round Bore Agricultural Bearings uses a triple-lip seal that retains grease well, but combine environments expose bearings to chaff and moisture. Over-greasing can push the seal lip outward, so apply grease slowly until slight resistance is felt.
Q: What causes premature failure of W208PP10 Round Bore Agricultural Bearings on combines?
A: The most common causes are misalignment during installation, contaminated grease, and incorrect locking collar torque. W208PP10 Round Bore Agricultural Bearings fail early when the housing bore is worn or when the shaft surface is scored. Always inspect the shaft and housing before installing a replacement, and confirm the bearing rotates freely by hand before reassembly.
Q: Are W208PP10 Round Bore Agricultural Bearings sealed on both sides?
A: Yes. The W208PP10 Round Bore Agricultural Bearings features contact seals on both sides to exclude dust, chaff, and moisture. This dual-seal design suits combine applications where airborne debris is constant. Inspect seals for cracking during installation.
Q: Can Demy supply cross-reference numbers for W208PP10 Round Bore Agricultural Bearings?
A: Yes. Demy maintains cross-reference data linking the W208PP10 Round Bore Agricultural Bearings to common OEM and aftermarket numbers. Provide your combine model, serial number, and the failed bearing dimensions, and the team will confirm the correct replacement.
