0801-50-72 SCREWTECH high precision ball screw

Product Description

The Cylindical 0801 Ball screw, this model withM-thread at the Nut end, the nut should be mounted using M-thread. It is suiyable for mountig with cylinder. This free-rolling ball force and motion passed between the screw and nut, this drive instead of a direct role in the way the traditional threaded screw vice screw and nut minimal rolling friction instead of sliding friction of the conventional screw, and greatly reduces the friction so that the ball screw transmission efficiency greatly improved. Precision ball screw transmission efficiency reaches above 90%, the traditional sliding screw in most cases only about 20-30%, and further, the driving torque of the whole transmission vice reduced to about 1/3 of the sliding screw vice. Precision ball screw series of testing equipment and quality control process to ensure the realization of high transmission efficiency.

Refer to the belowed picture, Code A : ROUND nut with thread, The return methods of the external circulation ball screw nut pair according to the ball circulation mainly include end cap type, intubation type and spiral groove type.The External circulation of 0801 ball screw is that the balls return to the screw and nut through the spiral groove or cannula on the outer surface of the nut and re-enter the circulation after the end of the circulation process. 
For the end cap type, a longitudinal hole is machined on the nut as a return passage for the balls. The cover plates at both ends of the nut are provided with return openings for the balls, from which the balls enter the return pipe to form a circulation. Intubation type, which uses elbows as return pipes, this structure has good manufacturability, but because the pipes protrude from the outside of the nut, the radial size is large. Spiral groove type, it mills a spiral groove on the outer circle of the nut, and drills through holes at both ends of the groove and is tangent to the threaded raceway to form a return channel. This structure is smaller than the intubation structure in radial size, but Manufacturing is more complicated. The outer circulation ball screw has a simple structure and manufacturing process and is widely used. The disadvantage is that it is difficult to smooth the seam of the raceway, which affects the stability of the ball raceway.
