They are indispensable key components in mechanical equipment. Typically made from metal or non-metal materials, they are thin-walled hollow cylinders. The primary function of bushings is to support and guide the rotational or sliding motion of the shaft, reducing friction and wear, thereby extending the service life of mechanical equipment.

Bushings play a crucial protective role in various mechanical equipment, specifically in the following aspects:
(1) Reducing Friction:
The use of bushings reduces friction between the shaft and the bearing housing, protecting mechanical components and extending the lifespan of the equipment.
(2) Reducing Vibration:
Bushings have good shock-absorbing properties, effectively reducing vibration during equipment operation and enhancing operational stability.
(3) Reducing Noise:
Bushings can effectively reduce noise generated during equipment operation, improving the comfort of the working environment.
(4) Ease of Maintenance:
Bushings have a simple structure and are easy to replace, lowering maintenance costs and downtime for the equipment.
(5) Simplifying Structure:
The use of bushings can simplify the design and manufacturing process of mechanical equipment.
Understanding the Principles and Specifications of Self-Lubricating Bearings
The materials for bushings are diverse, including soft metals, rubber, nylon, and non-metallic polymers. These materials are relatively soft and cost-effective.
In various harsh working environments, bushings can withstand vibration, friction, and corrosion, protecting the enclosed components. Bushings themselves are easy to replace when damaged and are cost-effective, offering good economic value.

(1) Pressure:
Select bushings made from appropriate materials and structures based on the operational load of the equipment to ensure they can withstand the expected working pressure.
(2) Speed:
Different bushing materials have varying adaptability to operating speeds; choose the right bushings according to the equipment's operational speed.
(3) PV Value (Pressure-Velocity Product):
Consider the PV value, which is the product of pressure and velocity that the bushing will experience during operation, to ensure durability.
(4) Load Nature:
Choose the appropriate type of bushing based on the nature of the equipment's load (e.g., static or dynamic load).
(5) Lubrication Condition:
The presence and condition of lubrication will also impact the performance and lifespan of the bushings.
Bushings, due to their simple structure, low cost, and durability, are widely used in multiple fields, including but not limited to:
Bushings are used in areas such as engines, gearboxes, and suspension systems to reduce direct metal-to-metal contact, thereby decreasing noise and vibration.
In machine tools, conveyor equipment, and pump systems, bushings are used to support rotating components and ensure smooth operation.
In appliances such as washing machines, refrigerators, and air conditioners, bushings reduce friction during operation, thus extending their lifespan.
In agricultural equipment such as tractors and harvesters, bushings reduce wear on mechanical components, thereby improving operational efficiency.
