Wholesale Hitachi ZAX870 Excavator Top Roller 4638433

GFM excavator top roller, developed specifically for Hitachi ZAX870 large excavators, uses forged alloy steel core and multi-layer sealing technology to precisely match the original equipment track system. Through dynamic load simulation testing, the product’s load-bearing capacity has been increased by 20%, effectively dispersing the impact pressure when the excavator is moving. The surface high-frequency quenching process makes the hardness reach HRC55-60, and with the embedded lubrication channel, it greatly reduces abnormal wear in harsh working conditions such as deserts and mines, and extends the overall service life of the crawler group by more than 30%.

The interior of the carrier roller adopts a labyrinth seal structure + imported nitrile rubber oil seal to avoid bearing jamming caused by mud and sand intrusion. The modular design supports rapid disassembly and assembly, reducing equipment downtime. Verified by a third-party laboratory, the radial runout error of the GFM carrier roller is still less than 0.08mm after 2000 hours of continuous operation, significantly reducing the risk of track deviation and subsequent maintenance frequency, helping users save more than 15% of annual maintenance costs.
