About Plastic Round Inner Bush 21mm

A plastic round inner bush typically refers to a cylindrical or round-shaped plastic component with an inner opening or hole. These components are commonly used in various industrial, automotive, or machinery applications to provide spacing, support, or reduce friction between two components. The "inner" aspect implies that it has a central opening designed to accommodate a rod, shaft, or another cylindrical component.

Key features of a plastic round inner bush:

1. Shape The bush is round or cylindrical in shape.

2. Inner Diameter The inner opening is designed to fit around a specific-sized shaft or rod. The inner diameter will depend on the intended use and application requirements.

3. Outer Diameter The outer dimensions of the bush, including its diameter, will depend on the specific application and the space available.

4. Length The length of the bush may vary based on the design and requirements of the application.

5. Material The bushing is made of plastic. The choice of plastic material depends on factors such as load-bearing capacity, wear resistance, and environmental conditions. Common plastic materials for bushings include nylon, polyethylene, and other engineering plastics.

Plastic round inner bushes are used to isolate components, provide support, or reduce friction in mechanical systems. They are often chosen for their corrosion resistance, lightweight properties, and ease of installation. The specific dimensions and material properties will depend on the intended application and the specific requirements of the design.

If you have a particular application in mind or need more detailed information about a specific type of plastic round inner bush, it would be advisable to consult with suppliers or manufacturers who can provide products tailored to your requirements.

FAQ's of Plastic Round Inner Bush 21mm:

Q: How is the Plastic Round Inner Bush 21mm installed in machinery?

A: The bush is designed for a press fit installation, which involves gently pressing it into the housing or shaft interface. No additional hardware or adhesives are required, simplifying the process and ensuring a secure, precise fit.

Q: What are the main benefits of using a self-lubricating plastic bush in rotating shafts?

A: Self-lubricating properties reduce friction and wear between the bush and the shaft, minimizing maintenance requirements. This ensures smooth operation, prolongs component life, and eliminates the need for external lubricants.

Q: When should I consider using a plastic bush over a metal one?

A: A plastic bush is ideal when chemical resistance and corrosion protection are important, such as in humid, chemical-rich, or outdoor environments. It is also preferred for moderate load applications where quiet operation and minimal maintenance are desired.

Q: Where can I purchase Plastic Round Inner Bush 21mm in India?

A: These bushes are widely available through distributors, manufacturers, suppliers, and traders across India. Many providers offer customizable inner diameter options to accommodate specific shaft sizes.

Q: What is the typical usage of a Plastic Round Inner Bush 21mm?

A: This bush serves as a spacer or alignment element for rotating shafts in general machinery. It helps maintain shaft position, reduces vibration, and ensures efficient power transmission under speeds up to 1,500 RPM.

Q: Does the bush withstand exposure to chemicals and extreme temperatures?

A: Yes, made from high grade plastic, it offers good chemical resistance and operates effectively within a temperature range of -20C to +80C, making it suitable for diverse industrial conditions.
