Chain Saver Sprockets • A unique design that incorporates a special flanged rim on either side of the sprocket body. The chain sidebars rest on the flange as the chain wraps around the sprocket. This configuration keeps the chain on true center and distributes the load over a greater contact area, thus reducing the rate of wear.
Traction Rim / Wheel • Essentially a sprocket without teeth. • Available as a solid, segmented or a segmented/split design.
• Ideal for single strand bucket elevators and/or abrasive conveyor applications. • Coefficient of friction must be great enough to allow the wheel to drive. • Key Benefit – Allows the chain to slip in an overload or obstructed condition.
Octagonal Wheel • Utilized with Heavy Duty Hard Faced Drag Chains. (See Page 243)
• Octagon shape allows the dynamic forces to be transferred directly between chain sidebars and the flats of the octagon. This eliminates the traditional sprocket tooth/ chain bushing wear point. • Guide lugs are typical and keep the chain on center. • Hardfacing available for extreme conditions.
Full-Face Drum Sprocket • Highly respected design regularly utilized with both Welded Mill and Welded Drag chain. (See Pages 195 and 234) • Full-Face design offers an increased surface area which reduces contact
pressures and in turn offers solid wear performance. • Available in single and multi-strand configurations.
A-Plate Drum Sprocket • Classic, traditional style utilized with both Welded Mill and Welded Drag chain. (See Pages 195 and 234) • Can handle misalignment quite well.
• Open design allows for bulk material pass through. • Available in single and multi-strand configurations.
