Frequently Asked Questions (FAQs)
1. Can bushings be used for linear motion?
Yes, bushings can be used for linear motion. While most bearings and bushings are designed for either linear or rotational motion, there are some products, such as NB stroke bush, that are specifically designed for linear motion. These bushings have raceway grooves along the axis of the shaft, allowing for linear movement.
2. What are the different types of shaft bushings?
There are three main types of shaft bushings: QD, taper-lock, and split-taper. Each type has different series with specific bore ranges that are compatible only with components designed for the same type and series of bushing.
3. Can you use a bushing instead of a bearing?
The choice between bushings and bearings depends on the application. Bearings are more suitable for high-velocity situations, while bushings are better for low-speed, heavy load applications. So, if the application requires low-speed, heavy load support, a bushing can be used instead of a bearing.
4. Why use a bushing instead of a bearing?
The decision to use a bushing or a bearing depends on the specific requirements of the application. In situations where high-velocity is a factor, bearings provide a better solution. However, for low-speed, heavy load applications, bushings are more suitable. They offer reliable support and can handle heavy loads with less friction.
5. What are the advantages of linear motion bushings?
Linear motion bushings provide several advantages. They help to bear loads with less noise and offer smooth, low friction movement along a single axis. These bushings are specifically designed for linear motion applications, and they are often more cost-effective compared to traditional round ball bearings. Additionally, they are easy to integrate into carriage designs.
