Description

If you’ve noticed grease leaking out of your trailer or implement hub, or dirt making its way into the bearings, you need this grease cap. A damaged or missing hub cap lets contaminants in and lubricant out—a recipe for bearing failure when you’re hauling grain at harvest time or moving equipment across the field. This replacement cap seals everything up tight and keeps your hub protected.

What You’re Getting

3.951-inch flange outer diameter for secure mounting to 848 series hubs
2.125-inch overall height provides proper clearance and coverage
Precision fit that seals out dirt, water, and debris
Heavy-duty construction built to handle field conditions and road vibration

Built for Real Farm Work

This grease cap is designed specifically for 848 series agricultural hubs commonly found on grain trailers, manure spreaders, and tillage equipment. These hubs see plenty of abuse from loaded trailers bouncing down farm roads and implements working through rocky ground. A good seal keeps the bearings happy and prevents expensive breakdowns during busy seasons.

Made to Last

Farm hubs take a beating from dust, moisture, and the constant stress of heavy loads. This cap is built to seal properly even after years of temperature cycles, chemical exposure, and the vibration that comes with agricultural work. The right materials and construction mean it won’t crack, warp, or lose its seal when you need it most.

Good to Know

Installation is straightforward—just clean the hub face thoroughly before installing the new cap to ensure a proper seal. Check your other hubs while you’re at it, since caps often fail around the same time. If you’re dealing with a stuck cap, gentle tapping around the edges usually frees it up without damaging the hub.
