Self-Adjusting Spring Bushings
A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.

MXL Series Corrosion-Resistant Timing Belt Pulleys
Anodized aluminum has good corrosion resistance. Pulleys are MXL series (miniature extra light) and have trapezoidal teeth. The teeth match up with the grooves along the inside diameter of a timing belt in order to move components forward or backward. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

Metal Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of carbon steel, they have high strength and are better than plastic gears and gear racks for high-load, high-speed, and heavy duty applications.
Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion.
For components to mesh correctly, they must have the same pressure angle and pitch.
Gears with machinable bore have a large hub diameter so you can machine them to fit your shaft.
Gears with hardened teeth are more wear resistant than gears with teeth that are not hardened. Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.

Plastic Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re also known as spur gears.
Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion.
For components to mesh correctly, they must have the same pressure angle and pitch.

Pulley Aligning Lasers
Check for proper alignment of pulley systems with these magnetic-mount lasers. Place them on pulleys, gears, or sprockets made of ferrous metals, such as steel.
Red lasers are best for indoor environments, since they’re dimmer than green lasers.
Green lasers appear up to 10 times brighter than red lasers, so they’re easier to see outdoors or in bright indoor lighting, as well as from far away.

Pocket-Sized Pulley Aligning Lasers
Slip this laser into your pocket so it's on hand to align belts, pulleys, chain, and sprockets. Economical and simple to use, just press the tool against the side of your pulley or sprocket and project the laser along your belt or chain to the aluminum target (included) to see any misalignment. It has a machined aluminum surface that is adjusted parallel to the contact surface for precise alignment.
Style B lasers have a threaded tip, so they’re compatible with converters.
