PURPOSE: A bearing screw transferring device with a steel ball type bearing holder is provided to reduce interference between an inner surface of a nut body and a screw shaft, to reduce costs by simply treating a bearing holder, and to endure high loads for a long time. CONSTITUTION: A bearing screw transferring device with a steel ball type bearing holder(1) comprises a screw shaft(29), a nut body(31), a radial bearing(11), and an anti-prevention cap(19). A screw(30) is formed in the outer periphery of the screw shaft. The screw shaft is inserted into inside the nut body. A plurality of installation holes(33) is formed in the outer periphery of the nut body along a path possible to accord with a helical path of a screw(35). The radial bearing is installed in the installation hole. Outer wheels are in contact with an exterior surface of the screw of the screw shaft, thereby rotating forward when the screw shaft rotates. The anti prevention cap prevents the bearing hole from being separated from the nut body. |
