MT Series Industrial Conveyor Chains, Durable & Reliable
Product Introduction
MT Series Conveyor Chains are heavy-duty, high-reliability transmission chains specially engineered for industrial material conveying systems, optimized for continuous, heavy-load, and harsh working condition applications. As a core traction component for belt conveyors, scraper conveyors, and apron conveyors, this series of chains features precise manufacturing, robust structural design, and excellent wear and fatigue resistance. It stably drives conveyor equipment to transport bulk materials (ore, coal, grain, cement clinker, etc.) in mining, metallurgy, building materials, grain and oil, and general industrial production lines, ensuring efficient and uninterrupted operation of conveying systems with low failure rates and long service life.
Compliant with international and domestic industrial chain standards, MT Series Conveyor Chains cover a full range of standard and customizable specifications, perfectly matching different conveyor models, conveying capacities, and working environment requirements. The product has been widely verified in actual industrial applications, with outstanding performance in tensile strength, impact resistance, and operational stability, and is the preferred transmission chain for medium and heavy-duty industrial conveying scenarios.
Core Product Features
-
High Tensile & Fatigue Resistance
Blanks are forged from high-quality alloy structural steel (40Cr/20Mn2/20CrMnTi), with integral quenching and tempering heat treatment for chain plates and pin shafts. Optimized thickened chain plate design and rounded corner stress relief treatment effectively enhance load-bearing capacity, resist long-term alternating tensile force during continuous operation, and prevent chain plate fracture and fatigue damage.
-
Superior Wear & Impact Performance
Pin shafts and bushings adopt carburizing, nitriding, and high-frequency quenching surface strengthening processes, with surface hardness reaching HRC58-62, ensuring excellent wear resistance of friction pairs. Precision-machined chain joints with tight and uniform clearances can withstand frequent impact and vibration from bulk material conveying, reducing wear of key components and extending the chain's service life.
-
Stable Operation & Low Friction
Chain plates are formed by precision cold heading, and pin shafts/bushings are ground by high-precision equipment to ensure consistent clearance of each chain link. The smooth mating surface reduces friction and noise during operation, avoiding jitter and stuck conditions in high-speed/heavy-load conveying, and improving the overall operational stability of the conveyor system.
-
Corrosion & Rust Resistance
Multiple surface treatment options are available for different working environments: black oxide finish for dry industrial sites, hot-dip galvanizing/electroplating for humid and dusty scenarios, Dacromet for mild corrosive environments, and 304/316 stainless steel material customization for strong corrosive working conditions (chemical plants, coastal areas). All treatments effectively resist medium corrosion and extend service life.
-
Easy Installation & Maintenance
Standardized modular design, equipped with dedicated connecting links, spring clips, and offset links, enabling quick on-site splicing, installation, and length adjustment. The simple and compact structure requires no complex daily maintenance; worn parts can be independently replaced, minimizing equipment downtime and reducing maintenance costs for customers.
