Accurate seed singulation means nothing if worn opener discs create a "W"-shaped trench bottom or seized gauge-wheel bearings cause depth bounce. We manufacture low-runout (≤0.4 mm) boron steel seed opener assemblies, hex-bore triple-lip bearings (205KRRB2 / 5203KYY2), and zero-lip gauge wheel tires for precision planting fleets.
Triple-lip sealed deep groove ball bearing engineered for high radial tillage shock loads and dust exclusion
Precision-ground boron steel no-till seed opener disc with pre-riveted double-row triple-lip bearing

On most 15.0" (381 mm) row-crop planters such as John Deere MaxEmerge and Kinze, opener blades should be replaced once worn down to 14.0"–14.25" to maintain proper blade-to-blade contact at the leading edge and prevent soil crumbling into the seedvee.
