PROBLEM TO BE SOLVED: To provide an actuator guide with a table on which a ball screw is mounted and which can travel on a rail via a linear ball bearing, having simple, easy and inexpensive construction while solving conventional problems on machining, function and assembly. SOLUTION: The linear ball bearing constituting the actuator guide has a synthetic resin ball circulation passage structure 2 inserted and joined into a U-shaped recessed portion 11 provided at the lower part of a metal structured table body 1. The structure 2 has a non-load ball hole 21 and a direction changing U-shaped groove 22 connecting a load ball groove 55 in the table body 1 to the non-load ball hole 21. COPYRIGHT: (C)2004,JPO
