Sprockets

Finished Bore

Plain Bore

Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.

Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.

Corrosion-Resistant 18-8 Stainless Steel—Won't corrode from frequent washdowns and mild chemicals, including ammonia often found in cleaning solutions.

Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.

Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

Idler Sprockets

Maintain constant tension on your roller chain to reduce wear and vibration. These sprockets press against the chain to take up slack and rotate freely on bearings to keep the chain moving smoothly. They’re often paired with roller chain tensioners.

For Single Strand

Ball Bearing

Ball Bearing—Smoother than smooth—the balls inside these bearings roll nearly friction-free to handle high speeds. All are sealed to keep lubricant in and dust out.

Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

Timing Belt Pulleys

Finished Bore

Keep your drive system in sync. Trapezoidal teeth mesh with matching belts to synchronize motion. With the original tooth profile, these pulleys handle enough torque for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD pulleys.

Steel—Strong but best for dry environments since moisture will cause them to rust.

Corrosion-Resistant Aluminum—Won't rust in wet environments and one-third the weight of steel and iron. However, aluminum pulleys are not as strong as iron and steel.

Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.

Flush Hub—Ideal in tight spots where a raised hub would get in the way.

Conveyor Belt Drive Sprockets for Food and Beverage Cut-Resistant Belting

Choose these sprockets when you need to expand your Ammeraal Beltech MPB conveyor line or replace its worn sprockets. Made of strong, durable polyamide, they withstand chemicals and a wide range of temperatures. All are FDA compliant for direct contact with food.

10 Teeth—Sprockets with ten teeth allow belts to run smoother than those with eight teeth, which prolongs the life of the belts. They can also handle heavier loads. The gaps between the belt plates, however, will be larger than those with eight teeth, so food may fall through.

High-Power Metal Helical Gears

The helical teeth on these gears stay in contact longer than straight teeth, which allows them to transmit higher loads at higher speeds than spur gears.

Crossed Gears

Crossed helical gears, also known as screw gears, can be configured to transmit motion at a 90° angle or in a straight line. To transmit motion at a 90° angle, pair two gears with the same tooth direction. To transmit motion in a straight line, make sure to get one left-hand and one right-hand gear.

For gears to mesh correctly, they must have the same pressure angle and pitch/module. To change speed and torque in your assembly, pair two gears with different numbers of teeth.

Plastic Timing Belt Pulleys

Naturally rust resistant and lightweight, these plastic pulleys are ideal for machines that require frequent washdowns. Trapezoidal teeth, the original tooth profile, mesh with matching belts to transmit power without slipping.

Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.

Plain Bore—Do it your way—machine the bore to your exact shaft size or add a set screw or keyway.
