Z Series Conveyor Chains are designed to meet diverse industrial conveying needs. These chains conform to BS standards, offering reliability and high performance in various applications. They are an essential component in material handling systems across multiple industries.
The basic Z - type conveyor chain consists of internal and external chain plates, sleeves, rollers, and pins. The chain plates are made of high - strength materials, often alloy steel, which are punched and processed with precision. The pins, usually made of heat - treated alloy steel, are inserted into the sleeves, and the rollers are mounted on the sleeves. This structure enables smooth movement and efficient power transmission.
Flexibility in Attachment: The ZC series' hollow pin design, in particular, offers great flexibility in attaching accessories. This allows for customisation of the conveyor chain according to specific application requirements, such as adding scrapers, baffles, or carriers to handle different types of materials.
High Durability: Through rigorous testing and analysis, the chain formula has been perfected. The combination of exterior hardness and a malleable core, achieved through innovative technology and heat treatment processes, ensures that the chains can withstand harsh conveying conditions in daily operation. The components are also shot - peened for greater fatigue resistance, extending the overall lifespan of the chain.
Smooth Operation: The precision-machined components, including the pins, bushes, and rollers, ensure smooth operation. The chains can run at relatively high speeds while maintaining stability, reducing the risk of material jams or disruptions in the conveying process.
