Metric Fast-Travel Ultra-Precision Lead Screws and Nuts
 |  |
Style A |
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 and number of thread starts.
Round Nuts—Right-Hand Thread
|
Style A |
Acetal—Acetal nuts have good wear and corrosion resistance.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
