Overview
There are several benefits to using DIN 22252 chain in industrial applications. Strength and durability: DIN 22252 chain is made of high-quality alloy steel, which provides excellent tensile strength and corrosion resistance. Resistance to wear and tear: The DIN 22252 chain is designed to resist wear and tear, even under heavy use, extending lifespan and reducing maintenance and replacement costs. Versatility: DIN 22252 chain is available in a variety of sizes and configurations, suitable for conveying heavy loads, lifting and hoisting equipment, and more. Precision engineering: Manufactured to strict specifications, ensuring precise dimensions and consistent quality, reducing the risk of chain failure. Compatibility: Designed to work with other components such as sprockets and attachments to form a complete chain drive system.

Applications

• Armored Face Conveyors (AFC)
• Beam Stage Loaders (BSL)
• Road header machines
• Coal plows
• Other heavy industrial and mining equipment requiring round link chain

Introduction
Round link chain, round steel link chain, round link mining chain, DIN 22252 mining chain, mining conveyor chain, flight bar chain system. DIN 22252 chain is designed and manufactured in accordance with the German standard DIN 22252, which specifies dimensions, materials, and characteristics. It is used across mining, construction and heavy machinery where strength and wear resistance are required.

Parameter
Material: carbon steel, high carbon steel, manganese steel, 20MN2 steel, 25mnV steel.
Chain treatment process: heat treatment, carburizing, blackening, electrophoresis, shot blasting.

Standards
DIN chain (German standard chain) can be divided into the following standards: DIN 766 chain (short link chain), DIN 764 chain (medium link chain), DIN 763 chain (long link chain), DIN 5685 chain, DIN 22252 chain.
