Your bearing is screaming, the seal is blown, and every pass through the field is grinding metal on metal. In agricultural equipment — balers, trenchers, disc harrows, roller mulchers — bearings operate in the absolute worst conditions on earth: constant dust, chaff, moisture, extreme shock loads from rocks and roots, and hour after hour of continuous rotation. A failed bearing doesn't just stop the machine — it scores the shaft, cracks the housing, and turns a $49 bearing job into a $500+ repair.
This is a direct drop-in replacement for Case IH / New Holland part number 47508398. It's the same industry-standard W209PPB2 spherical disc bearing the dealer sells for $90+ — same bore, same O.D., same seals, same load rating. The difference is the price tag.
Not all bearings are created equal — especially in agriculture. This bearing is purpose-built for the punishment that disc harrows, balers, and trenchers deliver:
This bearing directly replaces or cross-references the following part numbers across multiple manufacturers:
All of the above part numbers are the same physical bearing — same bore, same O.D., same seals. If your parts book calls out any of these numbers, this bearing fits.
This single bearing fits a massive cross-section of agricultural and industrial equipment:
⚠️ Always verify bore size before ordering. The W200 series comes in several bore variations. This bearing has the 1.7717" (45mm) ROUND bore. Some similar-looking bearings have square bores (W210 series) or smaller round bores. Measure your shaft or check your parts book.
The W200 series bearings come in multiple bore configurations. This specific bearing (47508398 replacement) has a 1.7717" (45mm) ROUND bore. Some disc harrow bearings — particularly those used on Kewanee discs — use a square bore (W210 series). A square-bore bearing will NOT work on a round shaft, and a round-bore bearing will spin freely on a square shaft. Verify your shaft profile before ordering.
Standard double-rubber seals (2RS) are designed for clean industrial environments. Agricultural equipment operates in extreme dust, chaff, and moisture. Standard seals will pack with dirt and fail within one season. This bearing features Tri-Lip seals specifically engineered for agricultural service — three independent sealing lips that exclude contamination far more effectively than standard seals.
The outer diameter of this bearing is curved (spherical), not flat like a standard deep-groove ball bearing. This is by design — it allows the bearing to self-align inside the cast-iron mounting flange to absorb shaft deflection under load. Do NOT attempt to substitute a standard flat-O.D. bearing — it will bind in the housing and fail under the first heavy load.
Is this the same bearing the Case IH dealer sells for $90+?
Yes. Case IH and New Holland do not manufacture their own bearings. Part number 47508398 is the industry-standard W209PPB2 spherical disc bearing — manufactured by companies like Timken (Fafnir) and NTN (BCA) and rebranded with the Case/CNH part number. Same bore, same O.D., same seals, same load rating.
Will this fit my disc harrow?
If your disc harrow calls for a W209PPB2 or DS209TT2 bearing with a 1.7717" (45mm) round bore and spherical O.D., yes. This is an industry-standard bearing used across dozens of disc harrow brands and models. Check your parts book for one of the cross-reference numbers listed above.
How long will this bearing last?
In typical agricultural service (disc harrows, balers), expect 2-5 seasons depending on operating conditions, soil type, and hours of use. Sandy or rocky soils are harder on bearings than loam. The Tri-Lip seals significantly extend life compared to standard-sealed bearings by keeping contamination out.
Can I grease this bearing?
No — this is a sealed, pre-lubricated, non-relubricatable bearing. It is factory-packed with high-temperature grease and designed to run for its entire service life without re-greasing. There is no grease fitting. This is intentional — in dusty agricultural environments, grease fittings are an entry point for contamination.
