Split-Tapered Bushings

Steel and Cast Iron

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. They're for use with split-tapered sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

Self-Centering Screw-Clamp Bushings

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

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 that are blue make it easy to identify metric collars at a glance. They’re tinted to match other blue metric fasteners.

303 stainless steel collars are corrosion resistant and highly machinable.

DIN 705 collars meet an international standard for shaft collar dimensions.

Two-Piece Shaft Couplings

Install and remove these shaft couplings without disconnecting the shafts, motors, and other attached components—they’re made in two pieces so you don’t need to slide them onto shaft ends. They’re also useful when you have limited access to the ends of the shafts. These couplings clamp onto the shafts, creating a secure hold that won’t mar them. Good for high-torque applications, they have a rigid construction. However, their rigidity means these couplings can only connect shafts that are well aligned.

Aluminum couplings are lightweight, making them useful in precision motion control and servomotor applications.

High-Speed Servomotor Precision Flexible Shaft Couplings

Connect shafts and ball screws to high-speed servomotors and stepper motors—these shaft couplings handle four times more speed than standard servomotor couplings. They’re often found on high-torque motors that frequently start and stop, such as those used with packaging machines, press brakes, and semiconductor manufacturing equipment.

With aluminum hubs joined by a flexible fluoroelastomer or nitrile rubber core, these shaft couplings dampen vibration and adjust for misalignment. When machines accelerate and decelerate quickly, these couplings remain stiff to maintain accuracy and repeatability, which prevents equipment from moving out of place. They also resist backlash, meaning all of the turning force from the motor is passed on to the connected shaft. The core resists water, petroleum-based chemicals, and inorganic acids while also insulating bearings, encoders, and other shaft components from stray electric current. Clamping screws provide hold without marring shafts; they’re useful in applications where shafts are frequently assembled and disassembled.

Clamping Vibration-Damping
Precision Flexible Shaft Couplings

Components of a Coupling Shown Assembled

(Each Component Sold Separately)

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. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).

A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.

Set Screw Flexible Shaft Couplings

Hubs and Spider Shown Assembled

(Each Component Sold Separately)

Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place. 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.

Buna-N spiders provide good vibration damping and chemical resistance. Hytrel spiders provide fair vibration damping and excellent chemical resistance.

High-Torque Set Screw Flexible Shaft Couplings

(Each Component Sold Separately)

Hubs, Split Spider, and Split Spider Cover Shown Assembled

The thick split spider on these couplings can take on twice as much torque as standard spiders, extending the life of bearings, seals, and motors. They are often used to connect motors to pumps, mixers, large conveyors, and other high-torque equipment. To assemble a complete coupling, you will need two hubs, one split spider, and a split spider cover (all sold separately). They are also known as jaw couplings.

The hubs connect to your shaft with a set screw, which bites into the shaft and holds the hub in place. They are keyed and bored to standard ANSI/AGMA 9002 dimensions and tolerances, which means they fit snugly on standard shaft sizes. Spiders act as a cushion between the two hubs, reducing vibration and compensating for slight shaft misalignment. No need to remove hubs, disconnect shafts, or move equipment to replace worn split spiders—they are split along one side for easy installation and removal. The split spider cover sits on top of the spider to hold it in place, completing the coupling.

These split spiders are all urethane, which holds up to repeated abrasion and is difficult to tear. Spiders with a medium-soft hardness rating are the most common choice for these couplings. Their softness allows them to absorb the most vibration. Spiders with medium hardness rating can handle higher torque than the soft spiders, but are not as good at damping vibration. Spiders with a max. temperature of 350° F hold up better near ovens and other hot equipment.
