Linear-drive nut - Amacoil
The Model RS rolling-ring linear-drive family now includes the RS8 drive nut. The new nut drive runs on an 8-mm-diameter, case-hardened and ground, smooth shaft with no threads to trap debris and cause clogs or jams, providing built-in overload protection. Drive-system components are protected from possible damage from the churning and grinding that sometimes occurs with linear-drive devices, resulting in less downtime for cleaning threads and making repairs.
