💡 What role does a trunnion bearing play in keeping disc harrows balanced during operation?

A trunnion bearing lets the main bars rotate freely while carrying the heavy weight of the shanks. It stops the frame from binding up when you change direction in the dirt. Fixing this joint is a handy move if your steering feels tight or the noise starts climbing. Pop in a quality new kit to restore that smooth pivot action instantly. See the key benefits below:

• Supports rotating shafts while absorbing lateral and vertical forces
• Cast iron housing resists cracks from flying rocks and debris
• Sealed bearings lock out mud to extend service life significantly
• Complete hardware kits remove guesswork from the rebuild process
