Ball Screws and Nuts Ready for Tranportation to India

Ball Screws and Nuts are a set of precision transmission components that convert rotary motion into linear motion. The core of Ball Screws and Nuts consists of a screw shaft with spiral grooves, a nut with built-in ball and ball return devices, and relies on the rolling of balls to transmit power between the two spiral grooves, greatly reducing the friction loss of traditional sliding transmission.

Core advantages of Ball Screws and Nuts are very prominent.

High transmission efficiency of Ball Screws and Nuts,

due to the replacement of sliding friction with rolling friction, the efficiency often reaches over 90%, far superior to ordinary sliding screws, and the energy loss is small; High positioning accuracy, coupled with preloaded designed nuts to eliminate gaps, improve rigidity, and adapt to high-precision control scenarios; Strong durability, the nuts are mostly made of 100Cr6 high-quality bearing steel that is quenched and hardened as a whole, which can withstand long-term heavy loads. With regular lubrication, the service life can be extended.
As the core component, nuts can be selected according to specific styles.

Divided into end cap type, reflux tube type, etc.

according to the ball bearing circulation method; According to the preloading method, it can be divided into double nuts, multiple nuts, etc. Among them, double nuts generate preloading through washers or relative torsion, and are widely used in high-precision equipment such as machine tools. Screw rods are often customized according to travel requirements, and nut sizes often follow relevant industry standards.

How high precision and cutting-edge fields of Ball Screws and Nuts do the applications of both cover.

Used on CNC machine tools to drive the worktable and tool holder for precise machining; The high reliability transmission requirements for aircraft landing gear and flight control systems in the aerospace field; Ensuring high-speed and smooth movement of components in new energy vehicles and industrial robots; In injection molding machines and lifting equipment, the efficiency of equipment operation is also improved by the characteristics of long stroke and high speed.

The installation of ball screws and nuts requires attention to precise alignment and fixation.

The maintenance core of Ball Screws and Nuts lies in regular lubrication and cleaning, which directly affect the transmission accuracy and service life.

The specific methods are as follows:

1、 Installation method

Preparation before installation: Check that there are no bumps or scratches on the surface of the screw shaft and nut, and clean the impurities on the installation surface; Confirm the size matching of screw support bearings, supports and other accessories, and pre assemble the ball return device to ensure smooth ball circulation.
Screw fixation: Adopting the method of fixing at both ends or supporting at one end to avoid bending and deformation of the screw during installation; The fixed seat and installation surface should be tightly fitted, and the bolts should be evenly tightened to prevent uneven stress.

Nut assembly: Slowly insert the nut into the screw shaft to avoid forced impact; If paired with a motor, it is necessary to precisely connect the screw through a coupling to ensure coaxiality and reduce transmission deviation and wear.
Gap adjustment: In high-precision scenarios, double nut preload needs to be adjusted to eliminate gaps through gaskets or threaded structures, thereby improving transmission rigidity and positioning accuracy.

2、 Maintenance methods

Regular lubrication: Check the lubrication status every week, inject special lubricating grease or oil, and cover the screw groove and nut inside; In harsh environments (dusty, high temperature), the lubrication cycle needs to be shortened to 2-3 days.
Cleaning and protection: Daily cleaning of dust, iron filings, and other impurities on the surface of the screw to prevent particles from entering the nut and exacerbating wear; When idle, it can be covered with a dust cover to prevent rust and foreign objects from entering.

Status check: Check the straightness of the screw, the looseness of the nut, and the integrity of the ball return device every month. If any abnormalities are found (such as increased transmission noise or decreased accuracy), stop the machine for maintenance in a timely manner.
Fault handling: If there is jamming or severe wear, the ball or nut needs to be replaced, and the positioning accuracy needs to be recalibrated after replacement to ensure normal transmission.
