ATL 25-2 Torque Limiter C/W Platewheel 12B1-38 (3/4″ Pitch 38 Tooth Simplex)
The ATL 25-2 Torque Limiter C/W Platewheel 12B1-38 serves as an essential protective component inside mechanical drive assemblies to safeguard equipment from overloads and unexpected system jams. Featuring an integrated 3/4″ pitch, 38-tooth simplex platewheel sprocket, it incorporates spring-loaded friction discs that slip when a torque peak occurs. These are preset by adjusting the integrated locknut, altering the exact spring force to reliably suit your specified minimum and maximum torque performance thresholds.
