| RC424 | Swing Jaw Tooth | AC4220B | 900 kg/piece |
Both parts are made of premium Mn13Cr2 high-manganese steel. They undergo specialized quenching and tempering heat treatment. The process boosts surface hardness to HRC 58-62. It also maintains strong internal toughness. The precision tooth profile is optimized via computer simulation. It ensures uniform force distribution during crushing. The stationary jaw forms a stable chamber. It prevents material slipping and guides materials to the crushing zone. The swing jaw delivers dynamic compression force. It squeezes materials against the stationary jaw efficiently. This set improves crushing efficiency by 18% vs ordinary jaw teeth.
They are manufactured to strict OEM standards with 5-axis CNC machining. Every production step is monitored by professional QC teams. Dimensional tolerance is controlled within ±0.3mm. This ensures perfect compatibility with AC4220B Jaw Crusher. No on-site welding, cutting or adjustments are needed. Installation is fast and hassle-free. It saves maintenance time and labor costs. It also minimizes equipment downtime. The products are packed in high-strength wooden cases with shock pads. This prevents damage during long-distance international transportation.
