When you're hearing unusual noise from the transmission or feeling vibration during shifts, it's often a worn bearing calling for attention. This precision ball bearing with its 50mm inner diameter and 80mm outer diameter is a common size used throughout the agricultural industry, and when it starts to fail, your tractor will let you know. Getting it replaced before it completely gives out saves you from bigger transmission headaches down the road. What You're Getting Sealed construction keeps grease in and dirt out, even in dusty field conditions Precision steel construction handles both radial and light thrust loads smoothly Built to OEM specifications for reliable performance season after season 16mm depth provides proper load distribution and extended bearing life Heat-treated steel races resist wear under the varying speeds and loads of tractor operation Built for Real Farm Work This bearing is designed for the transmission and drivetrain applications found in Massey Ferguson tractors from the 5400 and 5600 series. These are versatile tractors commonly used for field work, hay operations, loader duties, and general farm tasks where smooth power transmission is essential for getting work done efficiently. Made to Last Agricultural equipment bearings take a beating from constant vibration, shock loads, and harsh operating conditions. This bearing uses quality steel construction with proper heat treatment to handle the demanding environment of farm work while maintaining smooth rotation under load. Installation Notes This is a direct replacement bearing that typically requires basic hand tools and a bearing puller or installer for removal and installation. When replacing bearings in transmission housings, it's smart to check shaft condition and replace any worn seals at the same time to prevent contamination of the new bearing.
