When you’re running heavy equipment day after day, that grease seal in your hub is what keeps dirt and water out while keeping your bearings properly lubricated. If you’ve noticed grease seeping out or worse, heard that tell-tale grinding noise from your wheel bearing, this heavy-duty seal is what you need to get back to work without worrying about costly bearing failures down the line.
What You’re Getting
- Robust 4-inch outer diameter design built for agricultural hub applications
- Heavy-duty construction that handles the constant flexing and pressure from field work
- Precision fit for 3-inch shafts with quarter-inch thickness for proper seal compression
- Quality materials that resist cracking from temperature swings and chemical exposure
- Direct replacement that installs without modifications or special tools
Built for Real Farm Work
This seal fits the popular 281189 hub assembly commonly found on agricultural trailers, tillage equipment, and heavy implements. Whether you’re pulling a grain cart through harvest, moving disc harrows between fields, or hauling manure spreaders, this is the same quality seal that keeps commercial operations running smoothly.
Made to Last
Agricultural seals take punishment from mud, dust, chemicals, and constant vibration. This one’s engineered with materials that stay flexible in cold weather and won’t harden or crack from heat and UV exposure. The spring-loaded lip maintains proper contact with the shaft even as normal wear occurs, giving you reliable sealing season after season.
Good to Know
Clean the hub housing thoroughly before installing the new seal, and check the shaft for any grooves or rough spots that could cause leaks. Pack the seal lips with a thin layer of grease during installation to prevent dry running damage. If your old seal was difficult to remove, a seal puller makes the job much easier and prevents damage to the hub.
