Shaft Supports

Easy-Access Base-Mounted Shaft Supports

These two-piece supports allow access to the shaft without needing to slide out the shaft or uninstall the support. Use them to brace the end of a linear shaft when working with light to medium loads where shaft alignment is not critical. Tighten the included clamping screws to secure.

Base-Mounted Shaft Supports

Slide the shaft in to install, then tighten to secure. For use with light to medium loads where shaft alignment is not critical, these shaft supports brace the end of a linear shaft along the ground or other flat surface.

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.

Routing and Suspending

Floor-Mount Strut-Style Supports

Reduce noise caused by HVAC systems. These sturdy rubber supports isolate vibration caused by heat pumps and air conditioning units, resulting in a quieter facility. When used on roofs, they also keep components above puddled water, which can cause damage.

Adjustable-Height Floor-Mount Strut-Style Supports

Adjust supports to the exact height you need to route pipe, conduit, and tubing through strut-mount routing clamps and hangers.

Floor-Mount Clamp-Style Supports

For a secure hold on pipe and conduit suspended above the ground, these supports have a cushioned clamp provides a 360° grip while reducing vibration.

Floor-Mount Flange-Style Supports

Bolt directly to a pipe flange to suspend a run of pipe above the ground.

Floor-Mount Saddle-Style Supports

These U-shaped supports allows access to pipe and conduit after installation.

Roller Supports

Support lines that expand and contract. The roller on these supports compensates for movement in your line from changing temperatures.

Strut-Mount Routing Saddles for Insulated Pipe

Clip these saddles around the outside of strut channel for a quick way to route insulated tubing and pipe. Lips on either end of the saddle protect insulation from abrasion if the pipe should move.

Locators, Supports, and Stops

Any-Size V-Blocks

To hold and support large or small round or cylindrical workpieces, position these two-piece V-blocks to accommodate any diameter.

Adjustable-Angle V-Blocks

Use this block to hold workpieces at precise angles.

Economy V-Blocks

Hold and support round workpieces.

Hardened V-Blocks

Use these pairs of blocks to support long, round workpieces—secure with the built-in clamps.

Miniature V-Blocks

Place into larger V-blocks to hold small shafts and cylinders. Sets include two clamps that fit different diameters.

Magnetic V-Blocks

Magnetic surfaces on the bottom, back, and one V face of these blocks eliminate the need for mounting clamps and bolts.

Machinable V-Blocks

Easier to machine than hardened steel, these blocks can be customized to fit a workpiece.

Pin Punch-Out Blocks

Remove pins from workpieces by positioning the pins over the holes in these hardened steel blocks and tapping them out using a punch and hammer.
