Modern machine tools are used to shape parts made from materials such as wood, ceramics, metal, and others into the required shapes or forms. To achieve precision and reliability, processing equipment requires high-quality precision bearings, such as ball screw support bearings. Known for their durability and long lifespan, ball screw support bearings offer excellent axial strength and the ability to withstand high thrust loads without compromising precision, making them highly suitable for high-performance actuators.

Next, we will explore five key features that make ball screw support bearings a great solution for your machine tool applications.
Angular Contact Ball Bearings
Most ball screw support bearings are angular contact bearings, featuring a large contact angle, which offer the following configurations for ball screw support applications:
Double-sided sleeve. Includes two matching bearings.
Three-tier assembly. Includes three matching bearings.
A set of four matching bearings.
These bearings feature single and multi-row designs, making them highly suitable for various installation configurations.
2. High Rigid Series
Stiffness refers to an object's ability to resist shearing and deformation caused by forces. Our high-stiffness ball screw support bearings boast exceptional stiffness, making them highly suitable for machinery that must withstand significant thrust loads. They are designed to provide high axial stiffness while achieving high precision and performance with lower starting torque.
High-rigidity series bearings typically come with lubrication seals. Due to the performance requirements of high-rigidity components, lubricants and bearing guards are crucial for maintaining the bearing's lubrication.
3. High Load Capacity
One of the advantages of using ball screw support bearings is their ability to withstand high loads. Our high-load capacity ball screw support bearing series is designed for extended service life, featuring the capability to continuously bear high stresses, ensuring precise bearings maintain smooth operation for long periods.
When designing high-load-bearing bearings, factors such as ball diameter and contact angle must be considered to increase the rated load of the component. Their unique custom design allows them to withstand axial loads in both directions.
4. Lubrication
The design of ball screw support bearings allows them to operate at high speeds and under heavy loads. To ensure cleanliness and continuous operation, the components must be protected and lubricated. Lubrication helps protect roller bearings from dust and dirt, and actively reduces wear. Properly lubricated bearings contribute to improving the efficiency and functionality of the machine. Adequate lubrication also protects the bearings from harmful friction that can disrupt the machine's operation.
There are two main subclasses of lubricants:
Lubricant. Inject oil into the bearings before each operation.
As a long-term lubricant, it is typically applied every six months.
5. High-speed
These ultra-precision bearings feature high stiffness configurations for operation at higher speeds. To achieve this, the ball bearings themselves can be made from or coated with various special materials, such as steel or ceramic.
The speed of application depends on the bearing material. Ceramic bearings increase the speed of the machine while sacrificing the durability of steel.
