Machinable-Bore Clamping Shaft Couplings
For Keyed Shafts
For Round Shafts
One end has a finished bore size; the other can be machined to any size—great for connecting to uncommon shaft sizes and shafts that are undersized from wear or oversized from coatings. Slide these couplings onto your shafts and tighten the clamping screws for a secure hold that won’t damage the shafts. All of these couplings are rigid and must be used on aligned shafts. They prevent movement between the shafts, so they can handle high-torque applications.
Couplings for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than couplings for round shafts.
Steel couplings are a good option in dry environments.
303 stainless steel couplings resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.

Machinable-Bore Flexible Shaft Couplings
(Each Component Sold Separately)
Hubs and Spider Shown Assembled
Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings. Also known as Lovejoy couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment. A complete coupling consists of two hubs and one spider (all components sold separately). Fasten to your shaft with set screws (not included), which bite into the shaft for a secure hold. If the spider fails, the hubs will lock together, giving you time to shut down your equipment to prevent component damage and replace the spider. These couplings do not need lubrication.
Buna-N spiders are the most commonly used because they damp the most vibration, making them best for forward/reverse and start/stop motion. They resist oil and chemicals.
Polyurethane spiders can run at a higher torque than Buna-N spiders, but do not offer as much vibration damping. Use them for continuous motion. Similar to Buna-N, they resist oil and chemicals.
Hytrel spiders operate at the highest torque, but are less flexible than Buna-N and polyurethane spiders so they have less misalignment and vibration damping capabilities. Use them for continuous motion. Compared to Buna-N and polyurethane, these have the best oil and chemical resistance.

Machinable Shaft Ends
One side is unfinished for milling custom pulleys, threaded hubs, sprockets, collars, knobs, sensor targets, or just about anything imaginable; the other side is a one-piece clamping coupling for mounting whatever you’ve created to your shaft. Slide these ends onto your shaft and tighten the clamping screws for a secure hold that won’t damage your shaft.
Use flanged ends to make objects with larger ODs than straight ends, or add mounting holes to create a custom mounting flange for connecting components.
Ends for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than ends for round shafts.
Carbon steel ends are easier to machine than stainless steel. They have a black-oxide finish that adds a layer of rust resistance but should be used in primarily dry environments.
Stainless steel ends provide the most corrosion resistance but are more difficult to machine than steel.
