Sealed Joint (SJ) chains are designed to protect the pin and bushing from harsh chemicals, dry erosion and overall corrosion. Webster’s sealed joint design is comprised of a resilient Quad Seal housed in a hardened steel ring pressed over both ends of the bushings. This seal, positioned between the inner and outer sidebars, acts as a barrier to keep conveyed material and foreign particles out of the pin/bushing interface, in addition to helping retain the factory installed grease between the pins and bushings to enhance chain performance and wear life.

Apron conveyors are engineered to handle a variety of materials ranging from hot and abrasive to dry and fine.

Webster has the unique capability to retrofit most competitive, existing metric size floating attachment, central bucket elevator chains. Our chains are designed to fit into the existing OEM application, allowing the end user to utilize the same bucket punch hole sizes and locations, as well as run on the same traction wheels or sprockets.

Welded steel clinker chains are designed for applications where severe abrasion and/or high temperatures exist such as cold or hot cement clinkers. The sliding surfaces are hardface welded for additional wear resistance. Sidebars and wings are made from square edge bar for better scraping action and increased conveying capacity.

Turbo Series (TS) chains are used for bucket elevators operating under highly abrasive conditions. TS chains are backed by an exclusive four-year performance guarantee in cement mill bucket elevators.

Steel bushed roller (SBR) chains are manufactured with heat treated rollers, hardened bushings and pins, and steel sidebars. The roller type construction provides a lower operating friction which helps increase chain life and reduces conveyor design requirements. They are available in a variety of sizes, configurations and designs and can be used in tough industrial applications. SBR chains come with a variety of standard attachments for immediate delivery.

Webster manufactures chain sprockets from steel plate or cast iron. Steel plate sprockets are flame cut and flame hardened, while cast iron sprockets have chilled rims for maximum wear resistance.

Both cast iron and fabricated steel elevator buckets are available for the application required. Modern manufacturing methods and technical expertise insure quality and quantity production. Buckets are available in a variety of materials with numerous options such as hardface welding or wear lips to resist abrasion.
