Description
When you hear that grinding sound from your disc harrow that makes you cringe, you know it’s bearing time. A worn disc bearing doesn’t just make noise—it throws off your tillage pattern, wastes fuel, and can destroy the gang shaft if it fails completely. This sealed square bore bearing with 7/8″ inner diameter and 87mm outer diameter is built to handle the abuse that disc gangs dish out, keeping your tillage equipment running smooth through tough field conditions.
What You’re Getting
- Sealed construction keeps dirt and debris out while holding grease in where it belongs
- Square bore design provides secure fit on square gang shafts without slipping
- Spherical outer race shape allows for shaft misalignment that happens in real field conditions
- Superior sealing designed specifically for disc applications to keep contamination out
- Direct replacement for DS208TT11, L-512-B, and other common part numbers
Built for Real Farm Work
This bearing fits disc harrows used for cutting through corn stalks, incorporating residue, and preparing seedbeds. Whether you’re running a smaller utility disc for food plots or a heavy-duty tandem disc for primary tillage, disc gangs take tremendous abuse, especially in rocky soils or when working heavy residue. This bearing is engineered to handle those side loads and impacts that come with real farm work.
Made to Last
The bearing is designed specifically for disc applications, with superior sealing to keep dirt out and grease in. The prelube feature means it’s ready to install and go to work. The sealing system protects against debris intrusion that causes premature failure in field conditions, so you get the service life you expect from a quality bearing.
Good to Know
Clean everything thoroughly before installation – old grease mixed with dirt is like grinding paste. Check the shaft for wear where the bearing rides; a grooved shaft will quickly destroy your new bearing. While you have the gang apart, inspect all bearings on that shaft since they typically wear at similar rates. Pack with quality disc bearing grease, not general purpose.
