## Emerson Bearing's Precision Bearing Solutions
Below is an overview of our precision bearing offerings:
- **Ball Screw Support Bearings**: Designed for demanding operations requiring high rigidity, superior speed, minimal drag torque, and exceptional control over axial runout. These bearings are long-lasting and excel in high-performance actuators.
- **Ceramic Hybrid Ball Bearings**: These bearings feature silicon nitride balls placed within steel rings. Their ceramic composition makes them stronger than stainless steel bearings. Ceramic hybrid bearings boast high resistance to wear, excellent heat tolerance, superior vibration resistance, high rigidity, and no electrical arcing. Ideal for electrical machinery, they last up to five times longer than steel bearings.
- **Super Precision Angular Contact Ball Bearings**: These bearings perform exceptionally well in high-speed, high-tolerance, and rigid applications. When paired, they effectively support bidirectional axial loads. Incorporating ceramic materials and cages enhances their aberration resistance and temperature tolerance. Available in contact angles ranging from 15° to 25° and bore diameters from 10mm to 240mm.
- **Double-Row Roller Bearings**: Offering precise support, high radial capacity, and stiffness, these bearings often work alongside two-way angular contact thrust bearings as internally adjusting rollers.
- **Linear Motion Bearings**: Both rolling-element and plain linear bearings fall under this category. Found in equipment requiring precise controlled motion—such as automated and industrial machinery—our linear motion bearings deliver some of the lowest friction rates available in the market.
Applications for these precision bearings span robotics, sensitive precision instruments, aerospace jet engines, and other advanced technologies. However, selecting the appropriate ABEC class is crucial to ensuring optimal system reliability and performance.

## Understanding ABEC Ratings for Precision Bearings
The Annular Bearing Engineering Committee (ABEC) sets standards for the running and dimensional accuracy of bearings. ABEC ratings define the tolerance levels of bearings and have become an industry benchmark, mandating that manufacturers submit their products for evaluation.
While all bearings are technically "precision," they vary significantly in terms of precision. The ABEC system uses odd-numbered ratings (1, 3, 5, 7, 9), with higher ratings indicating stricter tolerances, greater efficiency, and superior speed capabilities. Most bearings carry an ABEC 3 rating. Lower ABEC ratings suffice for applications like alternators or rollerblades, while a rating of 5 is preferable for higher-limiting speeds. Machine tools typically require ABEC 7 or 9, and robotics often utilize bearings with an ABEC 7 or 9 rating.
Understanding ABEC ratings helps ensure you procure bearings that match your application’s needs without over- or under-specifying precision.

## Bearings for Robotic Automation
Industrial robotics frequently handle tasks like painting, product inspection, testing, welding, and assembly. Advances in technology have dramatically improved the speed, endurance, and precision of bearings used in automation, making robotic systems increasingly common in sensitive industries such as healthcare and other high-tech fields.
Robotic bearings follow meticulously planned paths across multiple axes, playing a pivotal role in motion control where repeatability is vital. High-precision bearings are indispensable in designing and maintaining such systems. Proper selection of materials, types, and lubrication specifications directly impacts bearing longevity and performance.
### Key Types of Precision Bearings Used in Robotics:
- **Single-Row Deep Groove Ball Bearings**: Ranging from miniature to extra-large sizes, these are the go-to bearings for most automation applications. Thin-section bearings, with their lightweight design, high-speed capabilities, and compact footprint, are ideal for placement in robot arm joints.
- **Roller Bearings**: These are ideal for heavy-duty tasks. Slewing rings are commonly used in main rotations and lifting equipment. Ceramic ball with stainless steel ring (hybrid) bearings and fully ceramic bearings are excellent choices for harsh environments like vacuums.
