Thrust Ball Bearings
 |
 |
For silky-smooth motion, the balls inside these bearings roll nearly friction-free. You'll often find them at the end of a shaft or between a stationary and rotating surface, such as on a propeller or rotary table.
These bearings come as three separate pieces—one cage and two washers. The cage holds the balls in place, while the washers create a surface for the balls to roll on. This design is easy to lubricate, but the oil will attract dust and grime since it's exposed.
Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
Stainless Steel—These bearings won't degrade from water or mild chemicals, such as the ammonia in cleaning solutions. However, they're not as strong as steel bearings.
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.

Weldable 4130 Alloy Steel Round Tubes

Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

Shims for Shortening Screw Shoulders
 |
 |
Pare down the shoulder on shoulder screws. Slide these shims under the screw head to create the length you need. Use them to tighten the hold on bearings, pulleys, and sprockets, or shorten the length of travel along the shoulder.
You can stack multiple shims to achieve the exact shoulder length or space you need.
18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these shims won't degrade when exposed to harsh weather, salt water, and most chemicals.
Stress-Resistant Spring Steel—These shims are harder and hold their shape better than carbon steel. Use them for high-stress applications, such as leveling heavy machinery. They're best for dry environments since moisture will cause them to rust.

Shim Assortments for Dies
 |
Keep a variety of shim ODs on hand to fit various die sizes. Restore your die to its original height for clean cuts in metal stamping. Dies shorten over time from wear and sharpening, which prevents your die punch from going all the way through and often causes annoying partial punches that require stopping to clear. Place these shims under your die to adjust its height, extend its life, and prevent jams.
You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.
Stress-Resistant Spring Steel—These shims are harder and hold their shape better than carbon steel. Use them for high-stress applications, such as leveling heavy machinery. They're best for dry environments since moisture will cause them to rust.

Ultra-Low-Friction Oil-Embedded Thrust Bearings
 |
Our slipperiest metal thrust bearings glide on machines with frequent starts and stops, such as conveyors. Their oil contains nonstick PTFE particles that reduce wear and heat, extending the life of your equipment. All are fabricated, lubricated, and inspected in the U.S.
841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.
Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away if the bearing heats up.

Press-Fit Drill Bushings with Head
 |  |
 |  |
Shown in Countersunk Hole | Shown in Standard Hole |
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.

Telescoping Tight-Tolerance Hardened Ultra-Wear-Resistant 440C Stainless Steel Round Tubes
 |
Tubes Sold Separately |
Adjust the diameter of your shaft or rod by nesting these tubes inside each other. They're also known as precision shim stock. You can be confident in their precision since they're held to a tight diameter tolerance. They also come hardened for extra wear and abrasion resistance.
With even more carbon than 440A, 440C stainless steel is one of the hardest types of stainless steel. It maintains its corrosion resistance in temperatures as hot as 800° F.

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.

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. For faster placement in and removal from sleeves, use a handle.
