Hitachi Excavator Sprocket Ex300-6 Ex330 Ex350 Ex400 EX300-1/2/3 excavator undercarriage parts chain sprocket
HIGH QUALITY,HIGH ACCURACY,LONG SERVINCE LIFE.
Adopting precision casting,guarantees the internal metallographic structure.The precision machining of mounting surface guarantees installed reliability and practical stability.
The Sprocket surface hardness ranges from HRC 48 to 56,depth from 4mm to 10mm.
The Segment surface hardness ranges from HRC 50 to 56,depth from 6mm to 10mm.
A thorough study of the original drawing presenting the performance requirements of the various OEMs (Original Equipment Manufacturers) will allow us to manufacture all the different types of sprockets available on the market. The best solution will be applied to our production line after rigorous analysis of the drawings and heat treatment.
Sprocket Rim
Terris delivers sprockets and segments for a very complete range of machines, from 0.8 to 100 tons. The sprockets and segments are suitable for both excavators and bulldozers.
The sprockets are first molded or forged and subsequently processed, giving them a special heat treatment. If steel does not contain sufficient quantities of carbon, then it becomes brittle during the hardening process. If only the surface is hardened, then the sprocket or segment will wear very fast over time. Therefore the sprocket teeth are hardened by means of induction hardening. Terris segments are forged with precision, finished and hardened under special conditions.
Sprockets and segments, also known in the branch as cogwheels, run between the excavator or bulldozer chain links. Moreover, this undercarriage component runs over the bushing that connects the two links of a chain. The cogwheel is installed around the machine’s drive gear and only serves to drive the chain, so it does not bear any of the machine’s weight.
