About Shafts

Thread-Mount Idler Rotary Shafts

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications. They have a retaining-ring groove, retaining ring, and spacers to position your component and hold it in place.

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.

Step-Down Rotary Shafts

A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings.

Flange-Mounted Shaft Supports

These shaft supports hold linear shafts perpendicular to the mounting surface.

Easy-Access Flange-Mounted Shaft Supports

A removable collar allows access to the shaft without unbolting the flange. For use with light to medium loads where shaft alignment is not critical, these carbon steel supports allow you to hold linear shafts perpendicular to the mounting surface. Secure the shaft by tightening the clamping screw.

Material Handling

Screw Conveyors

Add on to an existing screw conveyor or keep it running like new.

Wheel Axles

Replace worn or broken caster axles.

Captive Pins

Position, pivot, and align components. Also known as pilot pins and PEM® TP4, TPS, and MPP pins.

Captive Fastening Pins for Soft Materials

The grooves in these pins grip plastics and other soft materials. Press them in to hold panels together. Also known as PEM® TKA and TK4 TackSert pins.

Captive Fastening Pins

Often used in cell phones and laptops, these pins attach thin panels such as printed circuit boards to metal and plastic bases. Also known as PEM® TA and T4 TackPins.
