Description

When your range box starts whining, grinding, or feeling rough when you shift through the gears, worn needle bearings are usually the culprit. This small but critical bearing keeps shafts running smooth inside your transmission’s range box—the section that handles those all-important speed changes. A failing bearing can turn smooth shifting into a noisy, difficult operation that’ll have you dreading every gear change.

What You’re Getting

Precision-manufactured needle bearing designed to handle transmission loads and vibration
Hardened steel rollers and races that resist wear under constant operation
Compact design maximizes load capacity in tight transmission spaces
Direct replacement for worn original bearings—no modifications needed

Built for Real Farm Work

This bearing fits the range boxes in Massey Ferguson’s popular 300, 4200, and 4300 series tractors. These are the workhorses you’ll find on farms across the country handling everything from cultivation and planting to hay operations and loader work. The range box is what lets you match your ground speed perfectly to the job at hand, whether you’re creeping along for precision work or covering ground efficiently for transport.

Made to Last

Range box components take a beating from constant shifting, vibration, and the high loads that come with farm work. This bearing is built with precision-ground needle rollers and hardened races that distribute loads evenly for long service life. The sealed construction keeps contaminants out while holding proper lubrication in—critical for transmission components that run in harsh environments.

Good to Know

Range box work typically requires splitting the tractor, so this is usually a job for the shop rather than the field. Most operators tackle bearing replacement during major transmission service or when other range box components need attention. Always replace seals and check shaft tolerances when installing new bearings to get maximum service life from your repair.
