Cone Crusher Balance Weights

Cone crusher balance weights are the counterweight rings that keep the eccentric assembly running true. When a crusher's balance weight wears, cracks, or is mismatched to the eccentric bushing, the entire machine starts to vibrate out of tolerance - accelerating bearing wear, loosening structural bolts, and shortening the life of the main shaft. We manufacture replacement balance weights engineered to restore original dynamic balance, supplied factory-direct for cone crushers across multiple brands.

A cone crusher's crushing action depends on the eccentric spinning off-center at high speed. The balance weight offsets that off-center mass so the machine runs smoothly instead of shaking itself apart. Signs that your current balance weight needs replacing include:

• Increased vibration or noise at the main frame, even with normal feed and closed-side settings
• Premature wear on thrust bearings, countershaft bushings, or main frame liners
• Visible cracking, chipping, or corrosion on the counterweight ring surface
• A balance weight that no longer matches your current eccentric bushing after a rebuild or parts swap

Replacing a worn or incorrect balance weight is often far cheaper than the downstream damage it causes to bearings, the countershaft, and the main frame.

The safest way to source a correct replacement is to provide us with your crusher's brand, model, or original part number. If documentation isn't available, we can work directly from your worn part - our team measures the physical sample and rebuilds it as a 3D model for production.
