Modern machine tools play a crucial role in shaping parts from materials like wood, ceramics, metals, and more into precise forms and shapes. To ensure optimal accuracy and reliability, machining equipment relies heavily on high-quality precision bearings, particularly ball screw support bearings. Known for their durability and extended lifespan, these bearings deliver exceptional axial strength and can handle significant thrust loads without compromising precision. This makes them an excellent choice for high-performance actuators.
Below, we will explore five key features that make ball screw support bearings the ideal solution for your machine tool applications.

### 1. Angular Contact Bearings
Most ball screw support bearings fall under the category of angular contact bearings, which have a steep contact angle. These bearings are available in various configurations, including duplex sets (two matched bearings), triplex sets (three matched bearings), and quadruplex sets (four matched bearings). The single and multi-row designs of these bearings make them highly versatile and suitable for a wide range of mounting options.
### 2. High Rigidity Series
Rigidity refers to how resistant an object is to deformation when subjected to force. Our high rigidity ball screw support bearings excel in this area, offering unparalleled stiffness that makes them perfect for machines that require strong thrust loads. These bearings are engineered to provide high axial rigidity, ensuring precise performance even at lower starting torques. Additionally, they often come equipped with lubricant seals to maintain optimal performance. Proper lubrication and bearing guards are critical for preserving the longevity of these components.
### 3. High Load Capacity
One of the standout advantages of ball screw support bearings is their capacity to handle heavy loads over prolonged periods. Our high load capacity series is specifically designed with extended service life in mind. By optimizing factors like ball diameter and contact angle, these bearings can endure high stress levels without compromising precision. Their unique design enables them to support axial loads in both directions, making them indispensable in demanding industrial applications.
### 4. Lubrication
To ensure smooth and efficient operation, ball screw support bearings must be properly lubricated. Whether operating at high speeds or under heavy loads, these bearings require protection from contaminants like dust and dirt. Lubrication not only reduces wear but also enhances the machine's overall efficiency. There are two primary types of lubricants: oil, which is injected before each operation, and grease, a longer-lasting option typically applied every six months. Proper lubrication is vital to preventing damage caused by harmful friction and maintaining optimal functionality.
### 5. High Speed
In their high-rigidity configuration, these precision bearings are built to function at elevated speeds. The material of the ball bearings plays a significant role in determining operational speed. While ceramic bearings boost speed, they may sacrifice some of the durability associated with steel bearings. Therefore, selecting the right material depends on balancing speed requirements with durability expectations.
