Detailed Product Description

Ball screw assembly is a high-precise mechanical drive part made up of screw, nut,ball
bearing, sealing washer and other components, for there are ball bearing rolling
between the screw and nut, the ball screw can receive high movement efficiency,compared
with slide guide screw, the drive torque is under 1/3. So that it
is easy to translate turning movement to straight-line movement, also, it is easy
to translate straight-line movement to turning movement. It is a kind of further
expansion and development of traditional slide guide screw. The profound significance
of this development is the same as the transformation brought by rolling
bearing to slide bearing. Due to its fine friction character, ball screw assembly
is widely used in various industrial equipments, precise apparatus and precise
numerically-controlled machine tool. Especially in recent years, work as executive
unit of straight-line drive of numerically-controlled machine tool, it is broadly
used in machine tool industry, and greatly promotes the numerically-controlled
development of machine tool industry. All of these lie on several fine characters
as follows: high drive efficiency, high orientation precision, reversibility
of drive, long service life, good synchronous performance
