Over 80% of field bearing failures in high-speed disc cultivators and row-crop planters stem from liquid slurry, fertilizer, and dust ingress rather than rolling-element fatigue. Our maintenance-free hub units and special-bore agricultural bearings combine vacuum-degassed 100Cr6 (GCr15) raceways, multi-lip spring-energized cassette mud seals, stamped steel rock flingers, and synthetic polyurea grease to survive extreme tillage shock loads without relubrication.
Integrated heavy-duty 5-bolt flange bearing hub with cassette triple-lip seal for severe field tillage
Triple-lip sealed deep groove ball bearing engineered for high radial tillage shock loads and dust exclusion

Maintenance-free hubs integrate a double-row angular contact ball bearing inside a forged or ductile-iron flanged housing sealed with a multi-stage cassette labyrinth seal and pre-packed with synthetic polyurea grease, eliminating daily greasing labor and preventing over-greasing seal blowouts.
We stock standard 7/8", 1", 1-1/8", 1-1/4", and 1-1/2" square bores as well as 5/8", 3/4", 7/8", and 1" hexagonal bores across GW208, GW209, GW210, GW211, and 205KRRB2 series bearings, plus custom broached metric profiles.
Yes. We provide custom outer-ring laser engraving, VCI rust-inhibitor poly bagging, individual color boxes, and palletized export cartons for B2B bearing importers and implement OEMs.
