Downtime during peak harvest season can be a nightmare—especially when your equipment grinds to a halt because of a failed bearing.
Mud, Dust, and Harsh Operating Conditions
When you’re working in the field, your equipment is constantly exposed to tough environments—mud, dust, water, and debris. These elements can easily infiltrate unsealed bearings, causing contamination and premature failure. That’s why sealed agricultural bearings are a must for long-lasting performance. They keep contaminants out and lubrication in, helping your machines stay operational when you need them most.
Peak Season Overuse and Load Stress
During planting or harvest season, equipment often runs for long hours without a break. Overuse, especially when combined with heavy loads, increases stress on farm equipment bearings. If those bearings aren’t built for durability, they’ll wear out quickly. Selecting the right load-rated bearing for your application can make all the difference between uptime and a costly delay.
Improper Fitment and Housing Issues
A common cause of bearing failure is improper installation or a poor fit with the shaft or housing. Using a tractor bearing that’s not matched to your shaft type—whether hex, round, or flanged—can lead to misalignment, excessive wear, and mechanical breakdowns. Ensuring correct fitment is key to maximizing the life of your components.
1. Tractor Bearings
