Chains & Sprockets

When it comes to Engineer-class 81X sprockets there are four standard configurations. A-Plate, B-hub, C-hub, and split sprockets. However, we also supply idler sprockets that use bearings or bronze bushings depending on the sprocket size and application.

We supply the widest selection of 81X roller chain sprockets in the world! All of our 81x sprockets are manufactured using high-quality materials and are precision manufactured for optimum performance and working life. The majority of out 81X chain sprockets are manufactured from steel, but we also have cast sprockets.

TECHNICAL SPECIFICATIONS: ANSI Chain Number: 50, No. of Teeth: 17, Shaft Type: Needle, Bore I.D.: 1", Outside Diameter: 3.719" FEATURES & BENEFITS: Steel needle-bearing idler sprockets maintain proper tension Guides the chain around obstacles Prevents excessive chain wear and vibration Hardened steel teeth for durability Requires tightener shaft, sold separately

Leaf chains are built of interlaced plates held together by rivet pins. They are built with the same high degree of precision as our roller chains. Leaf chains are used for applications that require strong flexible linkage for transmitting motion or lift. Specially selected steel and unique heat...

Idler Sprockets spin freely on built-in bearings to guide and control slack in your chain. Idler sprockets are self-lubricating and quiet. Idler sprockets will extend the lifetime of a roller chain and sprocket.These sprockets are made with a built in ball bearing and are intended to spin freely when mounted. Idlers are for taking up slack and tensioning drives that incorporate long lengths of roller chain. These sprockets come standard with hardened teeth.

Side bow chains, also commonly known as a side flexing chain is manufactured for specialty applications that require a high-strength ANSI standard roller chain that has the capabilities of going around turns and side flexes. This is why side bow roller chains are also commonly known as side flex...
