Conveying

Sensor and Reflector Brackets for Conveyors

Brackets are sized to mount sensors and reflectors to a conveyor frame.

Track for Overhead Enclosed-Track Conveyors

Track provides the runway for trolleys, carriers, and chain in manual and powered systems.

Trolley Chain for Overhead
Enclosed-Track Powered Conveyors

Carry loads along a track with this series of smooth-rolling alternating vertical and horizontal wheels.

Carriers for Overhead
Enclosed-Track Powered Conveyors

Carriers attach loads to the trolley chain with a scissor-like action and pivot as the conveyor makes elevation changes.

Brackets for Overhead Enclosed-Track Conveyors

Use brackets to hang and join sections of enclosed track.

Cable Rollers

Easily move bulky cable and hose, even over edges, while keeping it off the ground.

Linear Motion Shafts

Threaded Linear Motion Shafts

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

Linear Motion Shafts

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Linear Motion Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

Step-Down Linear Motion Shafts

A shoulder near the end of the shaft allows for easy positioning of housings, shaft supports, and collars.

Hollow Linear Motion Shafts

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

Hollow Linear Motion Shafts with Material Certification

Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

Linear Motion Shafts with Machinable Ends

With 2" of each end softened, it's easier to machine a custom end for mounting. The rest of the shaft is case-hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.

Support-Rail Shafts

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating.

Shafts for Support Rails

Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. The tapped mounting holes match those on our Support Rails.

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.

Splined Shafts for Rotary and Linear Motion

Grooves on the surface of these shafts transmit rotary power while allowing bearings to move freely along the length of the shaft.

Straightedges

Use these highly accurate straightedges as a guide to scribe and cut straight lines and to check surface straightness.

Stepped Pipe Flange Aligner Pins

Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned.

Pipe Flange Aligner Pins

Insert a pair of these nut-and bolt pins into adjacent flange holes and tighten to align flanges before connecting two pipes.

Pipe Flange Aligner Pins with Horizontal Level

Ensure horizontal alignment of pipe flanges with a level rod that runs between two alignment pins.

Angle Rails for V-Groove Track Rollers

Use these rails with any track rollers that have a 90° V-groove.

A stop holds the drawer closed; pull firmly on the drawer to open.

Soft-Closing Heavy Duty Base-
and Under-Mount Drawer Slides

To prevent drawers from slamming shut and support them even if they’re tall and full of heavy equipment, these steel slides have soft-closing bumpers and mount to the top and bottom of drawers.

Under-the-Counter Drawer Slides

Mount these slides underneath countertops, desktops, shelves, and tables. They are often used to hold keyboard trays.

Roller Track Sets for Bypassing Cabinet Doors

For smoother operation, these sets include upper and lower roller track for hanging lightweight cabinet doors that slide past each other.

Cabinet Drawer and Door Rollers

No need for drawer slides or roller track—add rollers to wood cabinet drawers and doors for smooth operation.

Drill Guides and Bushings

Press-Fit Drill Bushings

Finish-Your-Own Press-Fit Drill Bushings

Larger OD tolerances than standard press-fit bushings allow for finishing. Bushings should be machine ground.

Made-to-Order Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Made-to-Order Metric Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part.

Press-Fit Drill Bushings with Head

The head prevents these bushings from being pushed through the jig when drilling pressure is extreme. The head sits above the jig plate or can be mounted flush by installing in a counterbored hole.

Made-to-Order Press-Fit Drill Bushings with Head

Choose the ID, OD, and length you need.

Metric Press-Fit Drill Bushings with Head

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. A flanged head on the top of the bushing acts as a stop, preventing it from moving as you push down your drill bit, reamer, or other cutting bit.

Made-to-Order Removable Drill Bushings

Choose the ID, OD, and length you need.

Removable Drill Bushings

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Removable Drill Bushings for Thin Metal

Insert these bushings into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in in place by a separate locking part.

Drill Bushings for Soft Metal and Wood

The serrations at the top of the bushing grip to prevent rotation and spin out.

A slightly undersized shank makes these pins easy to install and replace. Also known as slip-fit and lock-screw locating pins, they are held in place by a separate lock screw.

Slotted Bushings

When locating a workpiece using through-hole alignment pins, use one of these bushings and one standard bushing to prevent the pins from binding in your fixture.

Through-Hole Alignment Pins

Precisely align drilled holes in two parts.

Floating Locating Pins

The head on these pins slides side-to-side in one direction. Use one of these pins and one standard round-head pin to prevent jamming when loading and unloading workpieces with inconsistent hole spacing.

Screw-Mount Locating and Support Buttons

Mount through the counterbored hole with a socket head cap screw to support and position workpieces and fixtures from the bottom or side.

Threaded Locating and Support Buttons

Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket.

Press-Fit Locating and Support Buttons

To align two parts with more precision than standard spring plungers, these index plungers have a mating bushing that improves alignment and repeatability.

Inspection and Measuring Fixturing

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with ¼"-20 holes.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".
