SKU: SMA-143-79941 Hydraulic Cylinder Wear Ring for CNH Tractor Applications

When hydraulic cylinders start weeping oil or get that jerky, unpredictable operation, the problem is often a worn wear ring. This small but critical part guides the piston rod and keeps it centered in the cylinder bore, preventing metal-on-metal contact that ruins expensive hydraulic components. Without a good wear ring, you'll end up with scored cylinder walls, damaged seals, and hydraulic cylinders that cost far more to rebuild than they should.

What You're Getting

• Precise 2.89" outer diameter and 2.81" inner diameter for exact fit and proper clearances
• Half-inch thickness provides the durability needed for heavy-duty hydraulic applications
• Engineered plastic construction that won't score or damage cylinder walls like metal components can
• Direct replacement for OEM specifications - no modifications or special tools needed

Built for Real Farm Work

This wear ring is designed for CNH hydraulic cylinders found on Case and New Holland tractors, loaders, and implements. Whether you're rebuilding a loader lift cylinder, repairing three-point hitch hydraulics, or overhauling remote valve cylinders, this ring handles the constant pressure and movement that farm hydraulics demand. It's built for the kind of work where cylinders cycle thousands of times in harsh, dirty conditions.

Made to Last

Farm hydraulic systems don't get babied, and this wear ring knows it. The material resists the heat buildup from heavy use and won't crack or chip when dirt gets past the seals. It maintains its shape and dimensions even after years of pressure cycles, keeping your hydraulic cylinders operating smoothly and preventing costly internal damage.

Good to Know

Installing a wear ring properly is crucial for long life - make sure the cylinder bore is clean and free of scratches before assembly. A light coating of hydraulic fluid helps it slide into place without binding. If you're rebuilding the whole cylinder, this is the perfect time to replace the wear ring even if the old one looks okay - they're cheap insurance against future problems.
