Amco Grease Seal OEM #11017

Protect your Amco tillage equipment’s wheel hub bearings from the field’s most destructive enemies — soil, moisture, crop debris, and abrasive grit — with this Genuine OEM Grease Seal (Part #11017). AMCO Manufacturing is an industry pioneer in agricultural bearing protection, having developed the Protect-O-Shield triple-lip seal design that locks in grease and provides an extra layer of defense against dirt and debris. This factory-correct grease seal is precision-manufactured to exact Amco hub dimensional specifications — delivering the correct seal lip geometry, interference fit, and material durability required to keep bearing grease in and field contamination out across a full season of demanding tillage and transport operation.

What the Grease Seal Does:
The grease seal is the primary contamination barrier in your Amco tillage equipment wheel hub assembly. Seated at the inboard end of the hub, it creates a dynamic lip seal between the rotating axle and the stationary hub bore — simultaneously retaining the bearing grease that lubricates the inner and outer cones and excluding soil particles, moisture, crop residue, and abrasive grit that would otherwise enter the bearing cavity from the field environment. Without an intact, correctly seated grease seal, even the highest quality tapered roller bearing cones and cups will fail rapidly from grease starvation, abrasive contamination, and corrosion. A blown or failed seal allows material kicked up in the field to damage or clog bearings, causing costly downtime and unplanned bearing replacement.

Why Genuine OEM Seal Specification Matters:
Grease seals are precision components. Lip geometry, interference fit, lip material, spring tension, and overall dimensions must all be correct for the seal to function properly. An undersized seal leaks grease and fails to exclude contamination. An oversized seal may not seat fully in the hub bore, creating a bypass path for field debris. A seal with incorrect lip geometry or material may harden, crack, or take a set prematurely under the heat and chemical exposure of agricultural grease and field conditions. The genuine Amco OEM grease seal is engineered to the exact hub bore diameter, shaft diameter, and seal width of your specific equipment — eliminating all of these risks.

Signs Your Grease Seal Needs Replacement:

• Grease leaking or purging from the inboard end of the wheel hub during transport or field operation
• Visible dirt, grit, or moisture contamination inside the hub cavity when servicing bearings
• Seal lip cracked, hardened, torn, folded, or taking a set away from the shaft
• Hub running hot — possible sign of grease starvation from a leaking seal
• Bearing failure caused by contamination — always replace the grease seal when replacing bearings
• Routine bearing service — replace the grease seal every time the hub is disassembled

Key Features:

• Genuine Amco OEM part — not aftermarket or generic
• Factory-correct seal dimensions for exact hub bore and shaft diameter fit on compatible Amco equipment
• Precision lip geometry creates a reliable dynamic seal between the rotating shaft and stationary hub bore
• Retains bearing grease while excluding soil, moisture, crop debris, and abrasive grit from the bearing cavity
• Durable seal lip material engineered to withstand agricultural grease chemistry, field heat, and seasonal temperature cycling
• Re-lubricate bearings daily after each use and at end of season — a properly seated grease seal makes proper lubrication retention possible
• Direct OEM replacement — seats to factory interference fit in the hub bore

Important Service Notes:
Always replace the grease seal any time the hub is disassembled for bearing service — reusing an old seal after hub teardown risks immediate seal failure and bearing contamination. Install the new seal with a properly sized seal driver or socket that contacts only the outer edge of the seal — never drive a seal in at an angle or use a tool that contacts the seal lip. After installation, pack the hub with the correct specification grease before reassembling bearing cones and adjusting preload.

Companion Parts for Complete Hub Service:
