Types of Machined Bushes
1. Flange Bushings
Flange bushings feature a flange that helps prevent axial movement. These bushings are commonly used in applications where alignment is critical, such as in automation and aerospace systems. The flange design aids in maintaining the position of the bushing within the housing, making them ideal for high-precision environments.
2. Plain Bushings
Plain bushings are the simplest form of bushings, often made from bronze or brass. They are commonly used in agricultural machinery and hydraulic systems to reduce friction between moving parts. Their straightforward design allows for easy replacement, making them a popular choice for many applications.
3. Self-Lubricating Bushings
Self-lubricating bushings utilize materials such as PTFE or other oil-free substances to minimize friction without the need for additional lubrication. This quality makes them suitable for industrial machinery and automotive applications where maintenance access may be limited.
4. Custom Bushings
Custom bushings are tailored to meet specific engineering requirements. They can be manufactured from a variety of metals and plastics, making them highly versatile. Industries such as aerospace and automotive often rely on custom bushings to ensure optimal performance in demanding environments.
5. Collars
Mechanical collars serve to restrain movement and enhance the precision of interaction between moving parts. They are often used in power transmission systems to improve alignment and reduce wear.
Applications of Machined Bushes
Machined bushes find applications across various industries, including:
- Aerospace: Used in aircraft components to reduce friction and wear.
