5 Features of Ball Screw Support Bearings for Machine Tool Applications
Modern machine tools are essential for shaping parts from materials like wood, ceramic, metal, and more into precise forms. To ensure optimal performance, machining equipment requires high-quality precision bearings, such as ball screw support bearings. These bearings are known for their durability, long lifespan, and ability to handle high thrust loads without compromising accuracy. This makes them ideal for use in high-performance actuators and other demanding applications.
In this article, we’ll explore five key features that make ball screw support bearings the top choice for your machine tool needs.
**1. Angular Contact Bearings**
Most ball screw support bearings are angular contact bearings, which have a steep contact angle and come in various configurations:
- **Duplex Set**: Two matched bearings for increased load capacity.
- **Triplex Set**: Three matched bearings for even greater stability.
- **Quadruplex Set**: Four matched bearings for heavy-duty applications.
These designs allow for flexibility in mounting and provide excellent performance in different setups.
**2. High Rigidity Series**
Rigidity is crucial in machine tools that experience strong thrust loads. High rigidity ball screw support bearings offer superior stiffness, helping maintain precision and performance while reducing starting torque. Many of these bearings also include lubricant seals to protect against contamination and ensure long-lasting operation.
**3. High Load Capacity**
One of the main advantages of ball screw support bearings is their ability to handle heavy loads over extended periods. Our high load capacity series is designed with longer service life in mind, allowing them to withstand stress and maintain smooth operation. Factors like ball diameter and contact angle are optimized to enhance load ratings and accommodate axial forces in both directions.
**4. Lubrication**
Proper lubrication is essential for the efficient and long-term operation of ball screw support bearings. Lubricants help reduce wear, protect against dust and dirt, and minimize harmful friction. There are two main types of lubricants used:
- **Lubricating oils**: Applied before each operation for immediate protection.
- **Grease**: A long-term solution that should be applied every six months.
Choosing the right lubricant ensures smoother operation and extends bearing life.
**5. High Speed Performance**
Ball screw support bearings can be configured for high-speed applications. The materials used in the bearings—such as steel or ceramic—play a significant role in determining their speed capabilities. Ceramic bearings, for example, can increase machine speed but may sacrifice some durability compared to steel bearings.
