Selecting Compatible Lead Screws and Nuts
More
Metric Precision Lead Screws and Nuts
Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. 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.
932 bearing bronze nuts have good machinability and wear resistance. Manganese bronze nuts have good strength and wear resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
