Features:
(1) High Reliability
LIMON applies stringent quality control standards on every production process.With proper lubrication and use, trouble-free operation for an extended period of time is possible.
(2) Small friction & Smooth Operation
The high efficiency of ball screw is vastly superior than conventional screws. It takes less than 30% torque to make the linear motion into rotary motion.
(3) High Rigidity and Preload
The ball screw of LIMON is designed with Gothic arch groove, which makes the screw easy to rotate even using minimum axial play. To make the rigidity more appropriate to using condition, you can change the preload between one or two screw nuts to reduce axial play.
(4) High speed with low noise design.
(5) High lead circulate design to make sure running performance.

Ball screws are mechanical linear actuators that consist of a linear ball screw and ball screw nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball screw nut are used in transmitting forces to a stationary or dynamic load with high accuracy, precision, and repeatability.

The unique element of ball screws is the rolling balls in the helical groove which reduces the mechanical contact inside the linear ball screw assembly and replaces sliding friction with rolling friction. This mechanism significantly lessens the friction generated, which results in highly efficient power conversion. The efficiency of screws is measured by their capability to transform power utilized in exerting rotational force to the linear distance covered.

How is linear ball screw composed?

The main components of ball screws are the linear ball screw, ball screw nut, and the balls. We will discuss their important specifications and their impact on the operation.

What is linear ball screw types?

Ball screws may be categorized according to the mechanism of their ball recirculation. The ball recirculation mechanisms are grouped into internal recirculation and external recirculation systems.Internal Ball Recirculation, Deflector-Type Ball Screws, End Cap-Type Ball Screws, External Ball Recirculation.

We have different types of ball screws, we have rolled screws and ground screws, the precision of ground screw can reach to C3, the rolled screw can reach to C5.

How does a linear ball screw work?

A ball screw works in a similar way to a conventional lead screw, but the significant advantage of using a ball screw is that it uses balls running in the helical channel to transmit the load. In high precision applications it is often necessary to translate the rotary motion from a motor to linear motion for the payload. One way of achieving this is by using a linear ball screw.Ball bearings within a ball screw roll along the track in a similar way to ball bearings in a standard rotary ball race, therefore eliminating the sliding friction associated with linear ball screws. The ball bearings are continually recirculated through the ball screw nut, distributing the load and picking up lubrication along the way. Due to the use of rolling ball bearings within a ball screw, the internal friction is very low, meaning ball screws can offer a high level of efficiency and positional accuracy even at high torque and force loadings. Ball screws can be quite complicated and high-precision devices, meaning they can sometimes be slightly more costly compared to a typical lead screw. This is due to the complex machining and assembly techniques required to manufacture them. However, if your application requires a ball screw, the greater performance generally outweighs the cost.
