    Linear-drive nut - Amacoil

    April 29, 2013
    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.

    Featuring an extruded aluminum-profile housing, the drive has a standard 4-mm linear pitch. Four other pitch settings are available: 3.2, 2.4, 1.6, and 0.8 mm. An optional free-movement lever allows manual sliding of the drive on the shaft. If an application calls for frequent use of the free-movement lever, there is an option to pneumatically actuate the function to prevent excessive wear and extend the life of the drive.

    The RS8 features zero backlash linear motion and the inner race of each rolling-ring bearing is in constant point-contact with the shaft. Ten RS drive-nut models are available, each with a specific axial thrust capacity.
