The lead screw support can extend the service life of the lead screw and enhance its precision as well as the smoothness of its operation. It can be generally divided into the fixed end and the supporting end, with the supporting end mainly serving to support the lead screw. Our support rods are capable of withstanding high-intensity work and can adapt to complex working environments. The products feature a simple structure, making them convenient to install. They have excellent sealing properties, which can effectively keep out dust and impurities.

Product Highlights

The lead screw support is a key basic supporting component in the transmission system of ball screws or trapezoidal screws.

Modular Design for Simplified Assembly

Their modularity eliminates complex alignment steps, enabling direct bolt-on installation. For instance, the EK6 and EK8 models integrate compact 45° contact-angle bearings, optimized for miniaturized screw shafts to reduce spatial footprint while maintaining rigidity

Enhanced Stability and Precision

Axial and radial accuracy is ensured through preloaded bearings and specialized sealing systems. . Lubrication systems with lithium soap-based grease and dual-contact seals or gap seals prevent contamination.

Durability and Maintenance Efficiency

Constructed from wear-resistant materials such as hardened metals, the units resist corrosion and mechanical stress. Sealed lubrication systems, including lithium soap-based grease, enable long-term use without frequent maintenance. Certain models feature dual-contact seals or gap seals to protect against contaminants

Versatility in Application

Available in diverse configurations-including square (BK, BF), round (EK, EF), and flange-mounted (ZKLFA) types-they adapt to varying spatial and load requirementsAdjustable mounting interfaces allow fine-tuning of screw alignment, compensating for installation errors or thermal expansion

FAQ

01.After installation, the support bearing loosens during operation. What is the reason and how to solve it?

The main reason is that the installation process did not follow the specifications, and the radial locking screws of the axial locking nut were not properly tightened. For example, workers did not operate according to the manual during the installation of automated production lines. The solution is to reinstall strictly in accordance with the installation instructions to ensure that the radial locking screws of the axial locking nut are tightened in place.

02.After installation, it is found that there is a deviation in the fit between the support bearing and the ball screw. What may be the cause and how to handle it?

It is mostly caused by violent installation, such as tapping or colliding with the nut extended from the ball screw, or improper processing of the support bearing groove (forcibly pressing in external parts). For instance, when installing machine tools in a narrow space, workers may tap the nut with inappropriate tools, causing it to deform. When handling this issue, correct installation tools and methods must be adopted. If deformation has occurred, the damaged parts should be evaluated and replaced.

03.After installing the support bearing onto the screw, the lip of the seal ring is damaged. Why does this happen and what to do?

This is because the lip of the seal ring was not carefully protected during installation, leading to damage or deformation. This problem is prone to occur due to operational negligence when installing support bearings for CNC machine tools. The solution requires careful operation during installation. If the seal ring is already damaged, it should be replaced with a new one in time to ensure sealing performance.

04.The component wear of the support bearing accelerates during operation. What may be the reason and how to solve it?

The main reason is insufficient lubrication. Although the screw support bearing is factory-fitted with an appropriate amount of grease, lubricating oil (or grease) is not added regularly during use. This problem is particularly likely to occur in automated equipment that operates continuously for a long time. The solution is to establish a regular lubrication system, select and add appropriate lubricating oil (or grease) in a timely manner according to the equipment requirements.
