Standard Features
 
The Model 400-3 is our light duty tap unit with four inches of lead screw stroke and no rapid advance or rapid return. The lead screw spindle is spline driven to the main drive shaft and will disengage in either direction if an electrical failure occurs. The unit is equipped with a hardened and ground lead screw running in a bronze nut. Both members can be removed easily and replaced for service or when changing from one pitch thread to another. The stroke is controlled by means of two standard limit switches. Offered as optional are four (4) switches, with two being used as safety contingency switches. When using the unit with a multiple spindle head, the head must be supported on guide bars, and if used in a vertical position must be counterweighted. The unit comes complete with motor mounting bracket, sheaves, vee belts and enclosed belt guard.
