Precision balls are used in critical aeronautical bearings, guidance system balls for space and military applications, precision valves, automotive bearings and other applications where higher precision is necessary. Precision balls are defined by grade: The lower the number of the grade, the more precision to which the ball is manufactured.Numerous special applications require non-standard ball bearings. V Groove Guide Wheel bearings are precision ground, double row, angular contact bearings. Characterized by a low coefficient of friction and low torque, Industrial Airframe bearings are designed for applications of oscillating motion or slow intermittent rotation.

Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry.The purpose of deep groove precision ball bearings is to reduce rotational friction and support radial and axial loads. Radial Ball bearings can support moderate radial loads and moderate axial loads (parallel to the shaft). They can operate at high speeds.
