Bushings for 42mm Shafts

Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Quick-Disconnect (QD) Bushings

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) 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.

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.

Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

Quick-Grip Screw-Clamp Bushings

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.

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.

Flush-Mount Screw-Clamp Bushings

Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads and have higher torque ratings than self-centering bushings. When you tighten the included clamping 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 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.

Clamping Shaft Collars

These metal collars are stronger than plastic shaft collars. They clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.

Black-oxide steel collars have some corrosion resistance. Zinc-plated steel collars have moderate corrosion resistance. Anodized aluminum collars are lightweight like unfinished aluminum collars, but they’re more corrosion resistant and have better screw seating torque, which means they’re less likely to shift. 303 stainless steel collars have excellent corrosion resistance. 316 stainless steel collars have excellent corrosion and chemical resistance.

Quick-Release Clamping Shaft Collars

Installing and removing a collar is as easy as pushing down and lifting up a clamp lever. Collars clamp evenly around the shaft to create a strong, mar-free hold. All have a clamping screw to adjust lever tension. Made of anodized aluminum, they are lightweight with good corrosion resistance.

Clamping Two-Piece Shaft Collars

Without Keyway

These metal collars are stronger than plastic shaft collars. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.

Black-oxide steel collars have some corrosion resistance. Zinc-plated steel and chrome-plated steel collars have moderate corrosion resistance with a bright finish. Aluminum collars are lightweight and have good corrosion resistance. In addition to the benefits of aluminum, anodized aluminum collars have extra corrosion resistance, and you can tighten the clamping screw with more torque, so they stay in place. 303 stainless steel collars have excellent corrosion resistance. 316 stainless steel collars have excellent corrosion and chemical resistance.

Set Screw Flexible Shaft Couplings

Hubs and Spider Shown Assembled

(Each Component Sold Separately)

Each hub includes a set screw, 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.

A complete coupling consists of two hubs and one spider, or two hubs, one split spider, and one retaining ring (all components sold separately). Hubs for 1/2" shaft dia. and above (unless noted) and all metric sizes have a keyway.

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

Metal-Detectable Flexible Shaft Couplings

Hubs and Spider Shown Assembled

(Each Component Sold Separately)

Designed for use in food-processing applications, where a fraying spider could contaminate a batch, these couplings have a metal-detector-grade rubber spider. Small pieces of metal inside the rubber will set off a metal detector, alerting you to the problem. In addition to the rubber spiders, these couplings have 303 stainless steel hubs, so they resist rusting in wet and damp areas common to food production. Since they aren't made of FDA listed materials, however, they shouldn't come in direct contact with food.

Also known as Lovejoy and jaw couplings, these three-piece couplings reduce shock, handle minor shaft misalignment, and do not require lubrication. A set screw in each hub bites into your shafts to hold the coupling in place. Because the two hubs interlock with the spider, these couplings will continue to work even if the spider breaks or wears away. This fail-safe design gives you time to shut down your equipment before damage occurs to other components.

A complete coupling consists of two hubs and one spider (all components are sold separately).

Metal-impregnated Buna-N rubber spiders are best for jobs with frequent starting, stopping, and reversing. The most commonly used spider material, they resist chemicals and damp vibration.

Metal-impregnated Hytrel rubber spiders are best for systems with continuous motion. They handle higher torque than Buna-N spiders and have better chemical resistance. They are not recommended for systems with starting, stopping, and reversing.
