Oil-Embedded Sleeve Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
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.

Multipurpose Sleeve Bearings
These 932 bearing bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 660 leaded bronze bearings.

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. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.
All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. They also have internal chamfers, so it's easier to insert bits, pins, and punches into the bushing. Some bushings have internal chamfers on both ends, so no matter which end of the bushing is inserted into your jig, your bits, pins, and other tooling enter easily. Having an internal chamfer on the bottom of your bushing may cause shavings to get caught and bind as you remove the bit, however.
DIN 179 bushings meet dimensional and material standards that make sure they're compatible with other parts and tools. Although DIN 179 is no longer an active standard, it's still a common reference point for designers.

Ball Screws and Nuts
Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread direction and size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

Root diameter indicates the diameter the ball screw will be after machining away the threads.
