High precision ball bearing- Designed to meet the stringent quality and performance requirements of the aerospace industry
High precision balls are used in various aerospace applications, including aerospace bearings, actuators, control systems, valves, and measurement instruments. Their accuracy, reliability, and durability are critical for ensuring the safe and efficient operation of aerospace systems.
 

The characteristics of high-precision balls used in aerospace applications

High precision

Aerospace components require precise dimensions and shapes for their parts, so high precision balls need to have accurate diameter and roundness. High precision balls are classified according to precision grades such as ABMA grades, ISO grades, or DIN grades.

High temperature resistance

Aerospace components face high temperature environments during flight or space travel, so high precision balls need to be able to maintain their performance and shape stability under high temperature conditions.
 

Select materials

These balls are typically made from high-grade materials such as stainless steel, chrome steel, or ceramic. The material selection is based on the specific application requirements, taking into consideration factors like corrosion resistance, strength, and weight.
 

Special Coatings and Treatments

Depending on the specific application requirements, high precision balls can be coated or treated with special materials or processes to enhance their performance. Examples include coatings for corrosion resistance, lubrication, or temperature resistance.
