Product Description
Best Selling and Good Price Rolled Ball Screw SFU Series
Introduction
Ball screw assembly is consisted of screw, nut and ball. The function is transfer the rotary motion into linear motion or transfer the linear motion into rotary motion. This is further extension and development of slide ball screw. The important significance of development is as same as change of bearing from rolling motion to sliding motion. Because of excellent friction function, ball screw is widely used for all kinds of industrial equipments and precision instrument.
In order to meet the development of CNC machine tools, the company established "large, heavy-load, high-speed, high-precision" of product development direction. In product development, we opened DKFZD end-cap high-speed high-precision ball screw and CMFZD intubation large heavy-load ball screw etc.
At present, the company can produce the ball screw min. dia. of 6mm, min. lead 1mm; max. dia. 205mm; max. single length 10m, max. load more than 100 ton which of various applications; it can provide a mass of 2mP1grade,3mP2grade;5mP3grade;8mP5grade various ball screws, it's the professional ball screw manufacturer of all specifications.
Features
1. High transfer efficiency
Balls with free motion in the ball screw assembly transfer the force and motion between screw and nut. This transfer mode replaces the traditional transfer mode that screw shaft and nut effect directly. Therefore the minimum rolling friction takes place of the sliding friction of traditional screw. The transfer efficiency of ball screw will reach more than 90%. The drive torque of transfer unit reduces to 1/3 of sliding screw. This also reduces the heat release largely.
2. High positioning accuracy
Ball screw has low heat release, small temperature increase and with actions of pre-stretch and eliminating axial clearance in the process, which make ball screw have high positioning accuracy and repeating positioning accuracy.
3. Reversibility
Ball screw has not sticky friction like sliding screw. It clears crawl which may exists during transfer. Ball screw can achieve two transfer modes - from rotary motion to linear motion and from linear motion to rotary motion, and transfer momentum.
4. Long service life
Since the strict control of ball screw groove shapes, surface hardness and material selection, the actual life of ball screw is much longer than sliding screw.
5. Good synchronization
Due to smooth running, axial clearance elimination and consistency in manufacture, several sets of ball screw assembly can drive the same unit or several identical parts to obtain the good synchronization.
