A Comprehensive Guide to Maintenance-Free Roller Chains

This article provides a comprehensive overview of maintenance-free roller chains, outlining their unique characteristics, the array of product choices available, and their specific applications.

Overview of Maintenance-Free Roller Chains

WLY offers an extensive selection of specialty Maintenance-Free roller chains designed to cater to diverse application needs. These chains are typically specified for situations where the use of lubricating oil is prohibited. Although a well-lubricated standard generally offers a longer lifespan, there are certain applications where lubrication isn't feasible, making the use of self-lubricated or sealed roller chains essential.

Distinctive Features of Maintenance-Free Roller Chains

Maintenance-Free roller chains come with several unique features that set them apart from traditional chains. They offer oil impregnated powdered metal sintered bushings that release oil into the chain joint, resulting in reduced friction between the pin and bushing as the chain moves over the teeth. This unique feature ensures smoother operation and extended service life.

Types of Maintenance-Free Roller Chains

WLY offers a variety of Maintenance-Free roller chains, each designed for a specific application.

Sintered Bushed (SL-Series) Chains

These chains are rollerless and utilize thick-sectioned powdered metal bushings capable of holding a substantial amount of oil. They are particularly effective in applications where high-volume oil retention is required.

PT Type Roller Chains

PT Type chains have rollers that smooth the action over sprocket teeth, and their roller link plates are thicker to enhance strength. The side plates and pins feature special coatings that prevent rust, ensuring durability and long-lasting performance.

C-Type Roller Chains

C-Type chains have standard thickness side plates, offering less strength than PT Type but more than SL Type chains. They are typically used on small material handling conveyors.

P-Ring Chains

These chains employ a rubber seal to keep lubricating grease in while preventing the penetration of dirt and other contaminants into the pin/bushing bearing area.

Seal Guard Roller Chains

Seal Guard chains use a stainless steel seal to maintain lubricating grease, while preventing the penetration of dirt and other contaminants into the pin/bushing bearing area.
