Easy-Install Dry-Running Flanged Sleeve Bearings
A slit running along the length of these bearings allows you to quickly slip them into a housing—no tools required.
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.

Press-Fit Drill Bushings with Head
The head prevents these bushings from being pushed through the jig when drilling pressure is extreme. The head sits above the jig plate or can be mounted flush by installing in a counterbored hole. Drill bushings can also be used as spacers, shims, and machinery bushings.

Metric Fast-Travel Ultra-Precision Lead Screws and Nuts
Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size, thread pitch, and number of thread starts.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric Ultra-Precision Lead Screws and Nuts
Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
