Description

When your disc harrow, cultivator, or other implements start making noise or showing wobble in the drive components, it’s usually these medium-duty bearings that need attention. This 45mm bore sealed bearing handles the side loads and constant vibration that come with field work, keeping your equipment running smooth whether you’re cutting through crop residue or working rocky ground.

What You’re Getting

Rubber seals on both sides keep dirt and moisture out while holding lubricant in
45mm inner diameter fits common implement shafts and PTO assemblies
100mm outer diameter provides solid support in bearing housings
25mm width handles axial loads from gang pressures and implement weight
Pre-packed with quality grease designed for agricultural applications

Built for Real Farm Work

This bearing size is commonly found in disc harrows, field cultivators, and various PTO-driven implements where moderate loads and steady rotation are the norm. It’s the right choice for mid-size equipment that sees regular use but doesn’t face the extreme punishment of heavy-duty tillage gear. You’ll find this size in everything from rotary cutters to hay equipment.

Made to Last

The dual rubber seals protect against the dust, moisture, and debris that destroy standard bearings in farm conditions. AgSmart builds these to handle the stop-and-start operation typical of field work, plus the vibration that comes from working uneven ground and hitting the occasional rock or root.

Installation Notes

This is a direct replacement for most applications—no modifications needed. When installing, make sure the bearing housing is clean and check the shaft for wear grooves that could damage the new bearing. Pack with disc bearing grease if you’re working on tillage equipment, as it handles the heavy loads better than general purpose grease.
