Gauge Wheel Bearing for JD Planters

The 851-SMA885152 Gauge Wheel Bearing is a specialty ag stem bearing designed for press wheel and closing wheel assemblies on popular John Deere, IH, and Kinze planters. Built for durability in high-residue planting environments, this bearing features an integrated 5/8" stem with cross hole for secure mounting. Engineered to replace multiple OEM part numbers, it restores smooth gauge wheel operation and consistent row performance—because steady depth control starts at the wheel.
