When you're putting in long days at the controls and start hearing grinding or feeling vibration coming from the rear axle, chances are your half shaft bearing is calling it quits. This bearing supports the outer end of your tractor's half shaft where it connects to the wheel hub, handling all the torque and weight transfer that keeps your tractor moving through tough field conditions. A worn bearing doesn't just make noise—it can lead to expensive half shaft or hub damage if ignored. What You're Getting Precision-sized bearing at 67mm x 110mm x 24mm for exact fit and smooth operation Heavy-duty construction designed to handle the constant loads and impacts of farm work Quality sealing that keeps grease in and dirt out, even in muddy or dusty conditions Direct replacement that eliminates play and restores proper shaft support Built for Real Farm Work This bearing works hard in tractors that do everything from cultivating and planting to harvest work and loader operations. From the smaller Massey Ferguson 135 utility tractors up through the powerful 390s, plus Ford New Holland models ranging from compact 2810s to big 4WD machines, these bearings support the drivetrain components that transfer engine power to the wheels where the rubber meets the ground. Made to Last Half shaft bearings take tremendous stress from changing loads, turning forces, and the constant vibration of field work. This bearing is built with quality steel races and proper hardening to handle those demands year after year. The sealing keeps contamination out while maintaining proper lubrication, critical for long service life in agricultural applications. Installation Notes This bearing typically requires pressing out the old one and pressing in the new—not a job for a hammer and punch. You'll likely need access to a hydraulic press or bearing puller set. While you've got things apart, it's smart to check the half shaft for wear and inspect any seals that work with this bearing.
