MTG Starmet MA500 Weld-on Adapter 1MA500WC140/1MA500WC120/1MA500CC140

Long wear parts@ supply high quality aftermarket replacement MTG Starmet Weld‑on Central Adapter & MTG Starmet Weld‑on Corner Adapter. Our aftermarket replacement MTG Starmet Weld‑on Central Adapter (WC) & Corner Adapter (WL/WR) are heavy‑duty ground‑engaging tool bases,fit for the MTG Starmet hammer‑less twist‑lock tooth system. Central adapters are installed on the middle section of bucket lip to bear main digging and breakout loads. Left‑hand (WL) and right‑hand (WR) corner adapters are mounted at bucket corners, specially designed to resist side‑scraping, corner collision and eccentric wear in harsh construction, quarry and mining environments.

Weld-on center adapter 1MA500WC140 fit 140mm cutting edge thickness ,  its corner adapters can be 1MA500WL140/1MA500WR140 or 1MA500CC140 or 1MA500WS140 . The universal tooth are MA500E1/MA500EX ,and use locking 2MA500PR&2MA500R to fix ; These adapters need to use wear gap to prevent excessive wear, the wear cap are 4MA500M/4MA500MS/4MA50090L/4MA50090R.
Our aftermarket Mining-grade MTG bucket adapters are engineered for severe working environments. They have reinforced structural design, including features thickened stress-bearing roots, oversized welding base plates, and reinforced transition ribs that prevent weld tearing and fatigue failure during prolonged heavy-duty cycles. Precision-machined dovetail profiles ensure a tight, zero-play fit with corresponding bucket teeth, eliminating movement that could lead to accelerated pin and retainer wear.

Our high-quality heavy duty adapters can maintain stable structural rigidity under repeated rock striking, heavy material loading and high-friction ore digging. It greatly extends the service life of bucket assembly, also reduces replacement frequency and maximizes mine fleet productivity.
When welding mining heavy-duty bucket adapter, please note that professional welding operation is required during installation, need to control preheat temperature,welding speed and welding sequence。Before replace the damaged bucket adapters, need to do cleaning work upon the welding area.Proper welding is crucial for protecting the bucket adapter and extending its service life.
