When your Towner disc harrow bearing starts leaking grease or letting dirt work its way in, this specialized metric seal gets you back to cutting clean furrows instead of dealing with premature bearing failure. This is a special metric seal designed specifically for the 8445 Towner bearing assembly, and while it’s not a standard catalog item, it’s the right fix when you need it.
What You’re Getting
- Precision metric seal engineered for the 8445 Towner bearing specifications
- Quality construction that keeps grease in and contaminants out
- Direct replacement that restores proper sealing to your disc assembly
- Special order availability through quote process ensures you get the exact part needed
Built for Disc Harrow Work
This seal works with the 8445 bearing assembly that features a 4.724 inch outer diameter and 2.188 inch inner diameter, commonly found on Towner disc harrows used for seedbed preparation and residue management. Whether you’re working corn ground in the spring or incorporating cover crops, your disc bearings need proper sealing to handle the dirt, moisture, and debris that comes with tillage work.
Made to Last
Disc harrow bearings take a beating from constant rotation, side loads from uneven ground, and exposure to field conditions that can destroy inferior seals. This metric seal uses materials designed to handle the temperature swings and contamination levels that disc equipment faces during normal field operations.
Good to Know
Since this is a special metric seal, you’ll need to get a quote rather than ordering directly online. Have your bearing information ready when you call – the 8445 designation and any visible measurements help ensure you get the right seal. When installing, clean the seal bore thoroughly and check for any nicks or scratches that could cause the new seal to fail prematurely.
