Disc Harrow Bearings
Turner disc harrow bearings are engineered for agricultural tillage and other ground-engaging equipment operating in severe, contamination-heavy field conditions. Built to withstand soil intrusion, moisture exposure, vibration, and repeated impacts, they maintain high sealing performance and dimensional stability in applications where bearing replacement is difficult and downtime directly impacts productivity.
Round Bore
Round-bore disc harrow bearings are designed for assemblies built around round shafts, including legacy disc equipment and specialty agricultural machinery. Unlike square-bore designs that rely on mechanical drive geometry, round-bore units depend on proper shaft fits and retention methods to control torque transmission and axial movement. When correctly installed, they provide reliable performance in secondary disc gangs, finishing implements, and other assemblies where shaft geometry is fixed by equipment design and shock loads are more controlled.
Compatible with round shafts commonly used in legacy disc equipment and specialized agricultural implements.
Controlled shaft fits and retention systems are required to maintain proper torque transfer.
Well-suited for secondary disc gangs, finishing implements, and auxiliary assemblies where shaft geometry is predetermined.
The Turner Advantage
Heavy-duty triple-lip oil seals on both sides prevent contaminant ingress in soil-packed, abrasive environments.
Spherical outer diameters accommodate frame flex and housing misalignment, while cylindrical options provide a rigid fit in accurately machined housings.
Steel retainers withstand vibration, uneven loading, and repeated impacts in severe field conditions.
Greasable and non-greasable configurations support different maintenance strategies and contamination control requirements.
SAE 52100 steel rolling elements and raceways deliver high hardness and fatigue resistance for extended service life.
Designed for agricultural disc harrow assemblies where high seal drag is acceptable—and expected—for increased bearing protection.
