One-Piece Thrust Ball Bearings
In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
Bearings with nickel-plated cast iron housing are more corrosion resistant and durable than bearings with a cast iron housing.
Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.

Extra-Clearance Mounted Ball Bearings
Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases. All have a set screw for securing them to shafts without having to use a collar. The screw lets shafts rotate in both directions, so they’re good for applications where you need to reverse.

Easy-Align Mounted Ball Bearings with Two-Bolt Flange
An elongated mounting hole on one side of the flange lets you adjust the position of these bearings without having to remove your shaft. You only need to loosen the bolt instead of removing it to adjust. They’re self-aligning to compensate for shaft misalignment.

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.

Split-Tapered Bushings
The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.

Quick-Disconnect (QD) Bushings
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
