Hitachi ZAX470 Top Roller
The ZAX470 Top Roller, also known as an upper roller or carrier roller, is an important component of the excavator undercarriage system. Installed above the track chain, it supports the upper track assembly and helps maintain proper track position as the excavator travels.
MITNIK carrier rollers are manufactured with a focus on durability, dimensional accuracy and reliable sealing performance to support long-term operation under demanding construction, earthmoving and mining conditions.
Product About ZAX 470 TOP ROLLER
suitable for excavators, bulldozers, and skid steers track
The carrier roller is mounted on the upper section of an excavator's track frame and supports the weight of the upper track chain. By keeping the track chain properly positioned, the carrier roller helps reduce unnecessary friction and maintain smooth track movement.
For the Hitachi ZX470 series, different machine versions may use different upper roller configurations. Hitachi's official Selected Parts information lists 9099140 for ZX450, ZX450LC, ZX460LCH and ZX470 variants including ZX470-5G/5A/5G, while 9250478 is listed for another ZX470-5B application. This confirms that the exact part number should be matched to the machine version rather than treating one number as universal.
MITNIK supplies aftermarket carrier rollers designed to provide reliable track support and stable undercarriage operation. The roller is intended to work together with the track chain, lower rollers, front idler and sprocket as part of the complete crawler system.
For accurate replacement, customers are recommended to provide the complete Hitachi model, such as ZX470-5B, ZX470-5G or ZX470-6, together with the serial number or photos of the existing upper roller. This allows the correct configuration to be confirmed before quotation.
