Bushings for 28mm 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.

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.

Mounted Linear Bearings for Spline Shafts

A flanged housing with mounting holes connects these bearings directly to your system. They have a grooved inner diameter that's designed to work with spline shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. Wide and flat, the flange is especially useful for lifting and lowering loads on vertical shafts. All are for use where shaft misalignment is unlikely.

Also known as ball splines, ball bearings run with less friction than plain bearings, so they're smoother and more precise, even at high speeds. However, they don't transmit as much torque as plain bearings. They're commonly used for robotic systems and other automated applications that require complex, fast movements.

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.

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.

Washdown Clamping Shaft Collars

Suitable for use in washdown applications, these plastic collars also offer good chemical resistance. 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.

Acetal collars have a naturally slippery surface and resist swelling when exposed to moisture.

Tight-Hold Quick-Release Clamping Shaft Collars

A threaded lever lets you tighten these collars with more torque than other quick-release styles, ensuring that they stay put on your shaft. Use them to quickly move components or make setup changes, such as on packing equipment, printers, or label feeding machines. To make adjustments in tight spaces, lift the lever and twist to the side. Similar to a ratchet, you can lift the lever to disengage from the threads and reposition.

Black oxide steel collars are very strong, but will rust if exposed to moisture.

Anodized aluminum is strong and lightweight. It can withstand humidity without rusting, but water left on the surface will cause it to corrode.

303 stainless steel collars can handle frequent exposure to water without rusting.

Clamping Two-Piece Shaft Collars

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.

Servomotor Precision Flexible Shaft Couplings

Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications. Couplings are aluminum and stainless steel for corrosion resistance and allow zero backlash (no play). They grip evenly around your shaft for a strong hold without marring the shaft. Tighten the clamping screws to secure.

The included set screw holds the coupling in place. 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 nylon. Spiders are polyurethane for fair vibration damping and good chemical resistance.

Hubs, Split Spider, and Retaining Ring 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). Split spiders are easier to install and replace than standard spiders because there’s no need for tools or removing your hubs. Twist-lock them in place using a retaining ring.

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.
