A power-actuated jaw is provided for a vise including first and second vise jaws. The actuated jaw includes a force transfer mechanism adapted for transferring a force from a linear actuator, such as a pneumatic piston-and-cylinder unit, through pivoting and sliding subassemblies. The sliding subassembly mounts a jaw contact member and pushes same between open/retracted and closed/extended positions. A compressed air source is connected to the piston-and-cylinder unit through a three-way valve for cycling the actuated jaw through load/unload cycles.
