Double Clevis Features

Double Clevis Ball Screw Jacks - 1 Ton to 10 Ton

A double clevis ball screw jack is used when it is necessary to move a load through an arc, such as tracking antennas, hinged doors or air dampers. One clevis is mounted on the end of the lift shaft and the other clevis is welded to a heavy duty stem cover, which is welded to the housing. Depending on size, double clevis designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and rotary limit switches.

Note:

Mounting hardware for double clevis ball screw jacks should be specified as heat treated alloy steel clevis pins with at least 100,000 psi ultimate tensile strength.

Double clevis jacks used horizontally will have reduced column strength and life. For most horizontal applications, Nook recommends the use of an electric cylinder (contact Nook Engineering for more information).
