Description

When you’re working the fields with a coulter-equipped drill or planter, the last thing you need is a hub seal that’s letting dirt and moisture work their way into your bearings. A bad seal means contaminated grease, premature bearing wear, and potential downtime during planting season. This Timken oil and grease seal keeps everything sealed up tight so your coulter hubs keep rolling smoothly.

What You’re Getting

Genuine Timken quality that stands up to the constant rotation and pressure of field work
Half-inch width provides substantial sealing surface for reliable protection
Precision-engineered fit that creates the right seal without binding or excessive friction
Direct replacement design that installs without modifications or special tools

Built for Real Farm Work

This seal is specifically designed for 280501 and 633 gauge coulter hub applications, the kind you’ll find on no-till drills and planters that need to slice through tough crop residue and varied soil conditions. These hubs handle up to 1,500 pounds of capacity, so they see serious loads when you’re working through heavy residue or hitting rocks and hard spots.

Made to Last

Timken builds their seals to handle the punishment that farm equipment dishes out. The materials resist breakdown from heat, cold, and exposure to the oils and greases used in agricultural bearings. This isn’t a seal that’ll fail after half a season—it’s designed to keep doing its job through multiple planting and harvest cycles.

Good to Know

When you’re replacing this seal, it’s a good time to inspect the hub bearings and repack them with fresh grease. Clean out any old, contaminated grease and debris while the hub is apart. The seal should press in smoothly—if you have to force it, double-check that you’ve got the right part and that the hub bore is clean.
