What a bushing is, and how is it typically used in fasteners?
A bushing, also known as a sleeve bearing, is a cylindrical component typically made of metal, plastic, or other materials with low friction properties. It is used to reduce friction and wear between two moving parts, provide support, and act as a spacer or a guide within a fastening system. Bushings come in various shapes and sizes, including cylindrical, flanged, and spherical designs.
In the context of fasteners, bushings are often used in applications where a secure and precise fit is required. Here are a few common uses of bushings in fasteners:
Reducing Wear: When a fastener, such as a bolt, is repeatedly subjected to movement or rotation, the friction between the fastener and the surrounding material can cause wear over time. By inserting a bushing between the fastener and the material, the bushing absorbs the friction and wear, preserving the integrity of both the fastener and the material.
Alignment and Centering: In certain applications, it is crucial to align and center the fastener accurately. Bushings can help achieve this by providing a precisely sized opening that guides the fastener into the desired position. This is particularly useful in situations where misalignment or improper positioning can lead to functional or structural issues.
Electrical Insulation: In electrical applications, bushings can provide electrical insulation between the fastener and the surrounding components or structures. This is important to prevent electrical conductivity or to isolate components that require different electrical potentials.
Noise and Vibration Dampening: Bushings can help reduce noise and dampen vibrations that occur during the operation of fasteners. By absorbing and dispersing vibrations, they contribute to a quieter and more stable mechanical system.
Spacing and Clearance Adjustment: Bushings can act as spacers, allowing for precise adjustment of the spacing or clearance between components. This can be useful in applications where dimensional adjustments are necessary or where tolerances need to be accommodated.
