Introduction
The document discusses the design and heat treatment processes used by Rexnord to enhance the strength and wear life of their welded steel chains. The focus is on providing superior value and productivity through advanced manufacturing techniques.

Heat Treatment and Chain Design
Rexnord employs advanced heat treatment technologies to improve the hardness and toughness of chain components. This includes the use of computer-controlled furnaces and induction heat treating equipment. The process ensures that the chains have the hardest possible wearing surfaces while maintaining the necessary toughness to resist shock loads. The Selectively Induction Hardened (SIH) process is highlighted, which hardens only the parts of the chain that wear, ensuring durability without compromising toughness.

Maximizing Chain Wear Life
The document emphasizes the importance of heat treatment in extending chain wear life. By increasing the hardness of components, the wear life of chains can be significantly extended. For example, increasing hardness from 35RC to 60RC can potentially double the chain life. Rexnord's chains come standard with premium heat treatments, which are crucial for consistent wear life and predictive maintenance.

Maximizing Chain Strength
Rexnord chains are designed with superior fatigue strength due to tightly controlled interference fits between the pin and sidebar hole. This design increases the fatigue life of the chain and prevents unexpected failures. The document contrasts this with competitive chains that have poorly controlled fits, leading to lower fatigue strength.

Product Offerings
The document details various series of Rexnord chains, including the Narrow Series (WH, WHX, WSX) and Wide Series (WDH). Each series is designed for specific applications, with options for different materials and configurations. The chains are available with features like thru-hardened parts, selectively induction hardened rivets, and stainless steel construction.

Reverse Barrel Design
Rexnord has developed a reverse barrel design to address wear issues caused by scrubbing between the chain barrel and sprocket tooth. By reversing the barrel, the articulation occurs inside the chain joint, reducing wear and extending the life of the chain and sprocket.

Heavy Duty Welded Steel Drag Chains
These chains are designed for severe abrasion and heat conditions. They feature hardface welding on sliding surfaces, interference fits for improved strength, and induction hardened pins for longer service life. The design also includes square edges for efficient material conveyance.

Data Required for Selection
The document lists essential data for selecting conveyor and elevator components, including equipment life, environmental conditions, sprocket details, and material characteristics.

Maintenance Information
Maintenance guidelines emphasize the importance of proper chain connection and disconnection, safety precautions, and the use of appropriate tools. It advises against altering standard press-fit chains and highlights the significance of lubrication for extending chain and sprocket life.

Sprocket and Chain Interaction
Proper sprocket design and maintenance are crucial for preventing premature chain failure. The document suggests methods to increase chain and sprocket life, such as reversing sprockets to utilize unworn tooth faces and ensuring smooth chain-sprocket interaction.

Manual Lubrication: Apply a generous amount of oil manually to the chain, allowing it to travel two complete cycles. For high-speed operations, chains should be enclosed in an oil case with the lower strand dipping into the oil to maintain proper lubrication without excess.

Type of Lubricant: Use oil with the highest viscosity that flows at the operating temperature. Recommended oils are SAE 30 for below 40°F, SAE 40 for 40-100°F, and SAE 50 for above 100°F.

Chain Identification: Check for markings and measure various dimensions such as chain pitch, pin diameter, roller diameter, sidebar thickness, and bushing length.

Maintenance Information: Regular lubrication is crucial for maximizing chain life and conveyor efficiency. Under normal conditions, chains with rollers require proper lubrication. In environments where lubricants are not tolerated, service life may be compromised.

Lubrication Methods: Oil flow or brush lubrication is suitable for clean conditions, while flush lubrication is recommended for dirty environments. Direct oil between sidebars and roller faces for effective lubrication.

Storage Recommendations: Store chains in a dust-free environment, ideally in a container with used oil for protection and break-in lubrication. If dry storage is necessary, lubricate the chain before use and run it without load for 24 hours.

Chain Installation: Avoid grinding pins or sidebars to maintain press fit and chain reliability. Lubricate pins during installation to ease assembly.

Idle Equipment Maintenance: Clean chains and sprockets if equipment is idle, and cover with light oil to prevent corrosion.

Chain Operation: Manually lubricate weekly, focusing on areas with the least load. Apply oil quickly but allow the chain to complete two cycles.

Chain Assembly/Disassembly Tools: Use tools like Drivemaster and Linkmaster for safe and efficient chain assembly and disassembly, maintaining interference fit and chain fatigue life.

INTRODUCTION Strong, fatigue resistant chain is a function of the press fit of pins and bushings. The plexiglas models below help to illustrate this benefit. INTRODUCTION Fully machined pins offer dimensional accuracy critical in the manufacture of reliable, strong chain. In an unloaded state, a pin or bushing with a significant press fit will exert compressive stresses around the chain sidebar hole. Low or non-press fit components exert little to none. This photo shows the stress present around a press fit bushing and the lack of compressive stresses around the non- or lowpress fit bushings....
