Clamping Precision Flexible Shaft Couplings
Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screws to secure.
Spiral couplings have long cuts in their body for flexibility to handle parallel, axial, and angular misalignment better than parallel couplings. However, they’re not as rigid. Often used for light duty encoder and stepper drive applications, they allow zero backlash (no play) and never need lubrication. They’re also known as helical beam couplings.
Parallel couplings have short, intermittent cuts that make them more rigid and able to handle more torque and speed than spiral couplings, but they’re worse at correcting misalignment. Use them in high-torque applications, such as linear test systems and scientific instruments. They’re sometimes called slit couplings.
Acetal couplings are lightweight and corrosion resistant. Aluminum couplings are lightweight with good corrosion resistance.

Set Screw Precision Flexible Shaft Couplings
Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place. All are lightweight, corrosion-resistant aluminum.
Spiral couplings have long, continuous cuts in the body, making them flexible enough to handle parallel, axial, and angular misalignment. Often used for light duty encoder and stepper drive applications, they allow zero backlash (no play) and never need lubrication. They’re also known as helical beam couplings. Spiral couplings are less rigid than parallel couplings.
Parallel couplings have short, intermittent slits in the body that create rigidity and high torque capabilities. Able to handle higher speeds than spiral couplings, they’re often used in linear test systems and scientific instruments. They're also known as slit couplings. Parallel couplings do not handle misalignment as well as spiral couplings.

Precision Single U-Joints
A good choice when you need accurate and repeatable motion, these U-joints have zero backlash (no play), so there’s no motion lost when your shafts change direction. This keeps machines running smoothly. They’re single U-joints, so they connect and transfer torque between shafts that are misaligned at an angle.
Your shafts’ misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.
Pin-and-block U-joints work well in most applications since they handle higher torque at lower speeds than joints with ball bearings. Ball-bearing U-joints operate with less friction than pin-and-block joints, so they run at higher speeds.
Acetal U-joints weigh less than metal U-joints. They protect components in your system from stray electrical currents by blocking the flow of electricity between your shafts. 303 stainless steel U-joints balance strength with good corrosion resistance.
U-joints that connect with set screws don’t require you to drill any holes. U-joints that connect with spring pins require you to drill holes through both the U-joint and your shafts. Spring pins are not included.
U-joints that don’t require lubrication are often used with optical devices and other sensitive equipment because they're less likely to attract dust and debris compared to lubricated U-joints. They’re also easier to maintain.

Set Screw Shaft Collars
Keep these shaft collars in place by tightening their set screw into the shaft. The tip of the screw digs in for a secure hold, but will mar the shaft’s surface. For maximum holding power, make sure the set screw material is harder than your shaft material. Use these shaft collars to position and retain power transmission components such as sprockets, pulleys, and bearings. You can also use them to limit the movement of a shaft.
Carbon steel collars are strong and wear resistant. Collars with a black-oxide finish have some corrosion resistance, but only in dry environments. Their dark color can be useful for matching other parts in your system. Collars with a zinc-plated finish have an outer layer of zinc that protects the steel from rust and extends the life of the collar. Sintered steel collars are made from powdered metal, so they’re lighter than other steel collars.
303 stainless steel collars are corrosion resistant and highly machinable.
316 stainless steel collars are the most corrosion resistant while still being nearly as strong as steel collars. You can expose them to salt water, chlorine solutions, and chemicals without rusting.
Aluminum collars are lightweight and have good corrosion resistance.
Brass collars resist corrosion in wet environments, conduct electricity, and are nonmagnetic. If your system has other brass components, these collars create a consistent appearance.

Connection-Severing Flexible Shaft Couplings
To protect power-transmission components from damage, these couplings will shear or tear in overtorque conditions (approximately 10-20 times the maximum rated torque) to sever connections between shafts. They have a flexible center that not only compensates for misalignment, but also dampens vibration and shock loads. Couplings have no metal-on-metal contact, reducing noise and eliminating the need for lubrication. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.

Bore Reducers
Instead of replacing your shaft or keeping components, such as couplings, with various bore diameters on hand, these reducers adapt the bore of a component to a smaller size. Slide the reducer into the bore and use your component’s set screws or clamping mechanism to secure the shaft.
