### **Emerson Bearing’s Precision Bearing Offerings**
Here’s an overview of our precision bearing products, each designed to meet the demands of high-performance robotic systems:
- **Ball screw support bearings**: These precision bearings are ideal for high-speed, high-rigidity operations. They offer low drag torque, excellent axial runout control, and long service life, making them perfect for use in high-performance actuators.
- **Ceramic hybrid ball bearings**: Featuring silicon nitride balls between steel rings, these bearings are tougher than traditional Stainless Steel options. They provide superior wear resistance, higher temperature tolerance, and vibration resistance. Additionally, they eliminate electrical arcing, making them ideal for use in electric motors and other sensitive equipment.
- **Super precision angular contact ball bearings**: Designed for high-speed and high-tolerance applications, these bearings can handle bidirectional axial loads when used in pairs. With ceramic materials and cages, they offer enhanced stability and temperature resistance. Available in contact angles from 15° to 25°, with bore diameters ranging from 10 to 240 mm, they are widely used in precision machinery.
- **Double-row roller bearings**: These bearings offer high radial capacity and stiffness, making them ideal for heavy-duty robotic applications. Often paired with two-way angular contact thrust bearings, they ensure smooth and precise motion control.
- **Linear motion bearings**: Available in rolling element and plain types, these bearings are essential for any system requiring controlled linear movement. Our high-precision models offer minimal friction, exceptional accuracy, and reliability, making them suitable for industrial and automated equipment.
These bearings are commonly used in robotics, aerospace, medical devices, and other high-tech fields. Choosing the right ABEC class is crucial for ensuring optimal performance and longevity.

### **Understanding ABEC Classes for Precision Bearings**
The Annular Bearing Engineering Committee (ABEC) sets standards for bearing tolerances and dimensional accuracy. The ABEC rating indicates the level of precision, with ratings ranging from 1 to 9. Higher numbers mean tighter tolerances, better speed capabilities, and improved efficiency.
Most standard bearings have an ABEC 3 rating, while higher-end applications like machine tools or robotics often require ABEC 7 or 9. For example, robotic arms and high-speed automation systems benefit greatly from bearings with higher ABEC ratings due to their need for accuracy and durability.
While ABEC ratings are important, they are just one factor to consider. Proper material selection, lubrication, and design also play critical roles in bearing performance.

### **Precision Bearings in Robotic Applications**
Robots are now being used in a wide range of industries, including painting, welding, inspection, and assembly. As technology advances, the demand for more precise and durable bearings continues to grow. Robotic systems rely heavily on bearings to achieve accurate, repeatable motion across multiple axes.
High-precision bearings are essential in robotic joints and moving parts, where even the smallest deviation can affect performance. The right bearing choice not only improves motion control but also extends the lifespan of the entire system.
Some of the most common types of bearings used in robotic automation include:
- **Single-row deep groove ball bearings**: Ideal for a wide range of sizes, these bearings are lightweight, high-speed, and space-efficient, making them perfect for robot arm joints.
- **Roller bearings**: Preferred for heavy-duty applications, they offer strong load capacity and are often used in slewing rings and lifting mechanisms. Hybrid and full ceramic bearings are also popular in extreme environments such as vacuum chambers.
