Press-Fit Drill Bushings
Also known as jig bushings, these drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings.
Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.

Thin-Wall Press-Fit Drill Bushings
Drill holes close together. These bushings have a thinner wall than typical bushings to fit side by side in a fixture plate. Also known as jig bushings, they precisely guide bits and other cutting tools to ensure holes and cuts are consistent from part to part. You can also use them as spacers, shims, and machinery bushings. Made of hardened, ground steel, they resist wear and last for many cycles without needing to be replaced. Since their wall is so thin, these bushings may be slightly oval when you receive them but will conform to the shape of your hole.
Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.

Press-Fit Drill Bushings with Head
A flanged head on these bushings acts as a stop, so they won’t press through your jig even under extreme drilling pressure. They’re ANSI Type H bushings, also known as headed bushings. The head adds support and protects the jig from damage caused by heavy use, so they’re often used in jigs made of thin or soft materials. These bushings guide your drill bit, reamer, or other cutting bit to create accurate, consistent holes from one workpiece to the next. They’re also used as spacers, shims, and machinery bushings. Made of hardened, ground steel, they hold their shape and resist wear, so they last for many cycles without needing to be replaced.
To install, fit the bushing into a hole in your jig. In a standard hole, the head will sit above the jig plate; to mount flush, install in a countersunk hole. A chamfered edge on the bottom of the bushing helps center the bushing in the hole. Once it’s centered, press the bushing into place with a hydraulic or lever press.

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 (sold separately). By swapping in a bushing with a different ID, you can change the size of your bit and still use the same hole in your fixture. All are made to tight dimensional tolerances for consistent, accurate results, even as you change them in and out. They're also known as slip-fixed and renewable bushings.
Choose a sleeve with a length that matches the length of your bushing. To prevent bushings from spinning inside the sleeve as you drill, pair a standard sleeve with a lock screw, or use a locking sleeve.
Lock screws thread into a hole in your jig. The head of the screw fits into a notch on the bushing's head, which keeps the bushing from spinning.
For additional sizes, see Made-to-Order Removable Drill Bushings.

Sleeves for Removable Drill Bushings
Avoid wear caused by repeatedly pressing bushings into your jig fixture. Instead, press fit these sleeves into the fixture one time, and then swap bushings with different IDs in and out to change the size of your bit. Also known as type L headless liner bushings, they're sized for use with removable drill bushings (sometimes called slip-fixed and renewable bushings). Made of hardened steel, they won't wear as you slide the bushings in and out.

Vibration-Damping Oil-Embedded Mounted Sleeve Bearings
With a flexible layer of neoprene sandwiched between an oil-embedded bronze bearing and rigid steel shell, these bearings reduce wear and machinery noise. At startup, friction causes the bearing to release a thin layer of oil on the bearing’s surface. All are self-aligning to compensate for shaft misalignment.
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.

Low-Carbon Steel Round Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
DOM (drawn over mandrel) welded tubes are stronger than ERW (electric resistance welded) tubes.Tubes that are stress relieved minimize warping during machining.
