Product Description

 

Product Description

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw.

Rolled ball screws can not only be used in above general machinery, but also in many advanced industries. Rolled ball screw with a motor assembles electrical-mechanical actuator, which is more eco-friendly than hydraulic pump system. Nowadays it's applied to electric vehicles, solar power plants, railway devices and many medical and leisure equipments.

Precision ball screws have high smoothness and precise positioning, and at the same time have low torque, high rigidity, ultra-quiet and predictable long life characteristics.
The remanufactured ball screw has the advantages of high smoothness, long life and low price, and is generally used when the precision is not required.


Ball screw according to GB classification there are P class and T class, that is, transmission class and positioning class, the accuracy level has 1, 2, 3, 4 ..... Several kinds, foreign products generally do not distinguish transmission or positioning, all to C0 ~ C10 or specific values. In general, general-purpose machinery or ordinary CNC machinery selected C7 (any 300 stroke within the positioning error ± 0.05) or below, high-precision CNC machinery selected C5 (± 0.018) above C3 (± 0.008) below, optical or detection machinery selected C3 above.

There are many different series of ball screw shaft with nut, like SFU series, SFI series, SFE series, DFI series,  DFU series.Each series has its own characteristics, Let's look at the difference in appearance and characteristics.

Ball screw bearing specifications selection

(1) Determine the positioning accuracy;
(2) Determine the lead of the ball screw bearing by the motor and the speed requirement;
(3) Check the nut size to determine the stroke and related data of the shaft end of the screw bearing;
(4) Determine the average axial force and speed by load and speed distribution (acceleration and deceleration);
(5) Determine the pre-pressure from the average axial force;
(6) Determine the dynamic load rating by life expectancy, axial load and speed;
(7) Determine the outer diameter of the screw bearing and the nut form by the basic dynamic load rating, lead, critical speed, and DmN value limit;
(8) The outer diameter, nut, preload, and load determine the rigidity (machine design);
(9) Ambient temperature, total length of the nut to determine the thermal variation and cumulative lead;
(10)Screw bearing rigidity, thermal variation position to determine the pre-tension;
(11)Maximum machine speed, temperature rise time, and screw bearing specifications determine motor drive torque and specifications.

Ball Screw Features:

1.High Reliability
has very stringent quality control standards covering every production process. With proper lubrication and use, trouble-free operation for an extended period of time is possible.
2. Smooth Operation
The high efficiency of ball screws is vastly superior to conventional screws. The torque required is less than 30%. Linear motion can be easily changed from rotary motion.
3.High Durability
Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience, have resulted in the most durable ball screws manufactured.
