Mounted Ball Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
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.

Mounted Roller Bearings
Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.
Sealed bearings block out dust and contaminants.

Insert Bearings
Swap out worn inserts instead of replacing the entire mounted unit. Use the manufacturer model number on your existing mounted bearing to choose a compatible insert. Inserts must be used with the manufacturer model number specified.

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.

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.

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.
