A gimbal bearing is a type of bearing that allows for rotation around multiple axes. Gimbal bearings are commonly used in applications where high precision and accuracy are required, such as in aerospace, robotics, and medical devices.
Gimbal bearings consist of two or more concentric rings, with the inner ring fixed to the shaft and the outer ring fixed to the housing. The rings are separated by a series of balls or rollers, which allow for smooth rotation around the bearing's axes.
Types of Gimbal Bearings:
There are several types of gimbal bearings, including:
Type | Description | Advantages | Disadvantages |
---|---|---|---|
Single-axis | Allows for rotation around a single axis | Simple design, high precision | Limited range of motion |
Double-axis | Allows for rotation around two axes | Greater range of motion than single-axis bearings | More complex design |
Three-axis | Allows for rotation around three axes | Maximum range of motion, high precision | Most complex design, most expensive |
Gimbal bearings are used in a wide variety of applications, including:
When choosing a gimbal bearing, it is important to consider the following factors:
