Motor-Mount Positioning Slides

Connect to an electric motor with the included NEMA mounting flange. Slides have a precision lead screw, ball bearing carriage, and shaft coupling already installed.

Black-anodized finish slides are good for projects where aesthetics matter, such as prototyping. Their lead screw is PTFE coated to minimize friction for accurate movement and longer life. Use slides with photoelectric proximity sensors with plastic and paper. Slides with inductive proximity sensors are durable in oily environments, so they’re good to use with metal.

Travel distance per turn, also known as screw lead, is the distance a load moves with one revolution of the lead screw.

Note: Capacities listed are for horizontal mounting. When mounted vertically, the load capacity is cut in half.
