Ball Screw with Single Nut Flange Rotation SFR

Ball Screw with Single Nut Flange Rotation SFR
ISUTAMI SFR ball screw with single rotation nut, converts rotary motion into linear motion with minimal friction. It consists of a ball screw and a nut with recirculating ball bearings. The interface between the ball screw and the nut is made by ball bearings which roll in matching ball forms. With rolling elements, the ball screw drive has a very low friction coefficient and is typically greater than 90% efficiency. SFR ball screw and nut assembly is made to close tolerances and is suitable for use in situations where high precision is necessary.

Ball Screw with Single Nut Flange Rotation SFR Features

The ball screw is a high efficiency feed screw that rolls between the screw shaft and the nut. Compared to conventional sliding screws, the drive torque of this product is one-third or less, making it ideal for saving drive motor power. The ball nut determines the load and life of the ball screw assembly. The ratio of the number of threads in the ball nut circuit to the number of threads on the ball screw determines the extent to which the ball nut will reach fatigue failure (wear) faster than the ball screw.

The SFR assembly can be used in automotive power conversion unit, industrial robot, semiconductor, CNC router, laser milling, pick & go application. This high-precision ball screws are used in steppers for semiconductor manufacturing, and they are also integrated into actuator mechanisms of computer-controlled self-entertainment devices.

Features of SFR series as follows:
1.High smoothness.
2.High speed, low noise.
3.High rigidity.
4.Space saving
5. Mount and go.
