What Is an A Plate Sprocket?

A Type A plate sprocket is a flat sprocket without a hub. Because there is no hub, A plate sprockets are useful where space is limited, where the sprocket needs to be mounted to another component, or where the bore needs to be machined for a custom setup.

For #50 chain, the sprocket pitch matches the chain pitch of 0.625″, or 5/8″. The tooth count changes the sprocket diameter, speed ratio, and chain wrap, which is why choosing the correct size matters.

Common Applications for 50A Plate Sprockets

50 Chain A Plate Sprockets are commonly used in conveyors, agricultural equipment, material handling systems, packaging equipment, industrial machinery, OEM builds, and custom fabricated drive systems. They are a strong choice when a simple plate-style sprocket is needed and the mounting method is handled separately from the sprocket itself.

These sprockets are also helpful for machine shops and maintenance teams that need a blank or plain bore sprocket to modify for a specific shaft, weldment, fixture, or custom drive layout.
