In order to improve the working accuracy of the feed system, the ball screw mechanism must have a high transmission stiffness. In addition to increasing the stiffness of the ball screw itself, the ball screw mechanism must be designed with a sufficiently rigid support structure and must be installed correctly. The factors that affect the rigidity of the support structure include the stiffness of the bearing seat, the contact area between the bearing seat and the machine structure, and the stiffness of the bearing.
The ball screw is usually equipped with a special support bearing for the screw, with a contact angle of 60 °. This bearing has a large bearing capacity, low speed, and high accuracy. Generally, bearings need to be paired during installation. The specific pairing method should be determined based on the use of the machine tool, and the two ends of the ball screw are connected through bearings and bearing seats, and then connected through bearing seats and equipment. The screw nut is connected to the nut seat through flanges, keys, or threads. After installing bearings on both ends of the screw rod, fix the bearings with circlips or locking nuts. When the ball screw is working, it will produce axial force and requires bearings that can withstand axial thrust.
Universal ball screw, using angular contact ball bearings is sufficient. Install the bearings "face to face" on the two supporting shaft ends of the ball screw. If it is a specialized screw rod for special equipment, and if the equipment installation manual requires the use of specialized bearings, then assemble according to the relevant instructions.
A ball screw is characterized by its high efficiency, low temperature rise, high precision, high speed, high rigidity, high reversibility, low maintenance and long service life.
The product's efficiency is over 90%, and its superior surface quality and strict size of ball reduce friction between the ball and the track. The screw drive pair also achieves high positioning accuracy because of small temperature rise and pre tightening and clearance elimination.
Excellent design and manufacturing enable the machine to run at high speeds of over 60M/min while also having strong rigidity, thanks to pre tightening and clearance elimination. It has low maintenance requirements, with a special dust prevention device at the nut end and general care during operation.
The long service life is due to the materials of the screw rod and nut being processed with special materials, alongside a surface hardness of HRC62 of the screw (high carbon steel) and nut (alloy steel).

Packaging and Shipping for Linear Motion Guideways:
Linear Motion Guideways should be packed securely for shipping. All components should be protected and well-secured in the original packaging or a secure box. The package should be labeled with a “Fragile” sticker and have the appropriate shipping documents attached.
For international shipping, the package should be marked with the correct customs labels and documents. A tracking number should be provided to ensure that the package can be tracked during transit.
