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.
Square Bore
Square-bore disc harrow bearings are commonly used in modern disc harrow and tillage equipment built around square shafts. The square bore provides direct mechanical engagement with the shaft, eliminating the need for locking devices and reducing the risk of bore slip under heavy shock and reversing loads. This configuration is well-suited for primary disc gangs where soil resistance and rock strikes generate high torque and sudden load spikes.
Direct shaft engagement reduces the risk of shaft spin under high torque and shock loading without set screws or collars.
A positive drive connection handles sudden load spikes caused by soil resistance and rock impact.
Ideal for disc assemblies built around square shafts where durability and simplified field maintenance are priorities.
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.
