About Roller Chain and Sprockets

More

Sprockets

Sprockets for ANSI Roller Chain

Sprockets for ANSI Roller Chain

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

Wear-Resistant Sprockets for ANSI Roller Chain

Wear-Resistant Sprockets for ANSI Roller Chain

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Corrosion-Resistant Sprockets for ANSI Roller Chain

Corrosion-Resistant Sprockets for ANSI Roller Chain

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

Wide-Hub Idler Sprockets for ANSI Roller Chain

Wide-Hub Idler Sprockets for ANSI Roller Chain

A wide hub provides these sprockets with stability under heavy loads.

Bushings for Chain and Belt Drives

Quick-Disconnect (QD) Bushings

testString

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys.

Taper-Lock Bushings

default

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws.

Split-Tapered Bushings

Split-Tapered Bushings

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings.

Quick-Grip Screw-Clamp Bushings

Quick-Grip Screw-Clamp Bushings

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed.

Light Duty Sleeve Bushings

Light Duty Sleeve Bushings

Reduce the ID of sprockets, pulleys, and gears in low-torque applications.

Metal Gears and Gear Racks

Metal Gears and Gear Racks—20° Pressure Angle

testString

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. They're also known as spur gears.

Metal Gears and Gear Racks—14 1/2° Pressure Angle

testString

A former industry standard, 14½° pressure angle gears are often found on older machinery.

Metal Worms and Worm Gears

testString

Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.

Metal Bevel Gears

testString

A type of miter gear where one gear is smaller than the other, bevel gears provide right-angle speed reduction at ratios ranging from 2:1 to 5:1. They’re more efficient than worm gears because they create less friction.
