Amco Inner Cone OEM #10353

Maintain factory-correct bearing geometry, reliable load support, and long hub service life on your Amco tillage equipment with this Genuine OEM Inner Cone (Part #10353). AMCO Manufacturing has been building agricultural implements since 1947 and pioneered agricultural anti-friction bearings — including the triple lip sealed and regreasable bearings used across their disc harrows, ditchers, levee plows, and wheel offset harrows. This authentic inner cone is precision-manufactured to exact Amco specifications — delivering the correct taper geometry, roller contact profile, and dimensional tolerances for proper bearing preload, smooth axle rotation, and dependable performance through seasons of demanding field and transport use.

Inner Cone vs. Outer Cone — Know Your Components:
In a dual tapered roller bearing wheel hub assembly — as used across Amco’s tillage equipment line — the inner cone is the inboard bearing cone positioned closest to the equipment frame or axle center, while the outer cone (#10295) is the outboard cone positioned toward the outer end of the hub. Each cone works with its corresponding bearing cup (outer race) to establish correct internal geometry and load-sharing across the hub assembly. The inner cone typically carries the higher share of radial load from equipment weight, making its condition critical to overall hub integrity and bearing service life. A failed or worn inner cone cannot be compensated for by adjusting preload — replacement is the only correct service action.

What the Inner Cone Does:
The non-separable cone assembly consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers. Internal clearance is established during mounting by the axial position of the cone relative to the cup, and this conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical ball bearings. In Amco tillage equipment wheel hubs, the inner cone must withstand continuous radial loads from equipment weight, axial thrust loads from side forces during cutting and turning, and shock loads from field obstacles — all while operating under varying temperatures, exposure to soil, moisture, and field debris across an entire working season.

Signs Your Inner Cone Needs Replacement:

• Visible pitting, spalling, scoring, flat spots, or heat discoloration on the cone rollers or raceway
• Rough, grinding, or notchy rotation when the hub is spun by hand with bearing preload released
• Excessive hub play on the axle that cannot be corrected through preload adjustment
• Abnormal heat at the inner bearing position during transport or field operation
• Bearing contamination from a failed seal or grease loss requiring complete hub teardown
• Routine bearing service — always replace inner and outer cones and their cups as a complete matched set
• Inner cone damaged from over-tightening, improper installation, or impact with a field obstacle

Critical Service Notes:
Always replace the inner cone together with the inner cup, the outer cone (#10295), and the outer cup as a complete bearing set — mixing new and worn components dramatically shortens the service life of all components and wastes the cost of new parts. After assembly, set bearing preload to Amco’s factory-specified torque value, verify smooth hub rotation by hand, and monitor hub temperature during initial field operation. Bearings should be re-lubricated with appropriate conforming grease at the end of each season.
