brass bushings Advantages
Excellent Wear Resistance
The bushing brass's inherent hardness and natural lubricity effectively reduce frictional losses during long-term reciprocating motion, extending the life of core equipment components.
Excellent Thermal Conductivity
The brass bush's excellent thermal conductivity quickly dissipates heat generated by friction, ensuring stable operation.
Excellent Corrosion Resistance
The brass bush bearing operates stably in complex environments, such as humid, dusty, and mildly acidic and alkaline environments, reducing the probability of failure due to corrosion.
Excellent Machinability
Brass is easy to cut and form, allowing for precision machining to produce bushings that meet complex dimensional requirements, shortening production cycles.
Significant Self-Lubricating Properties
Eliminating the need for frequent external lubrication, the bushing maintains basic operation even in emergency lubrication conditions, reducing downtime and maintenance.
High Cost-Effective
The brass bushing threaded's balanced and reliable performance in wear resistance, corrosion resistance, and thermal conductivity effectively reduces overall equipment replacement and maintenance costs over long-term use.
brass bushings Applications
Automotive & Transportation
Power transmission and moving parts in automobiles and other vehicles require extremely high wear resistance and reliability, and brass flange bushing are a key component. At the hinge points of components like shock absorbers, control arms, and steering knuckles, flanged brass bronze bushing reduce wear between metal parts, improving the stability and service life of the suspension system.
Industrial Machinery And Equipment
In the realm of industrial machinery and equipment, flanged bush bearings play a pivotal role, particularly in essential components like conveying systems. These bearings serve a multifaceted function, not limited to supporting and guiding rotating parts. Beyond this, they provide crucial stability to various machinery elements such as pumps and compressors.
Home Appliances & Healthcare
Brass bearing bushing threaded are also widely used in consumer and medical equipment requiring high precision and safety. They are used in precision components such as washing machine drum shafts, refrigerator compressors, operating tables, and dental chairs, reducing noise and ensuring safety.
Mechanical Manufacturing And General Machinery
This is one of the core applications of brass bearing bushings. In the guideways and sliders of lathes, milling machines, grinders, and other machine tools, as well as in the transmission components within the spindle box, brass or bronze bushings can extend the life of the equipment by reducing direct metal-to-metal friction through their inherent lubricity.

A: We primarily use standard brass grades such as H62, H65, and H59. We can recommend the most suitable material based on the customer's specific application environment.
Q: What is the tolerance range for brass bushings?
A: The tolerance for standard brass bushings is ±0.01mm to ±0.03mm, depending on the product size and structural complexity.
Q: Do you offer custom sizes?
A: We fully support custom sizes, and we can produce sizes ranging from 3mm ID to 200mm OD and lengths from 5mm to 500mm. Customers simply provide detailed drawings (including dimensions, tolerances, surface finish, and other parameters), and our technical team will evaluate feasibility and provide a production plan.
Q: How are the wear resistance and service life of the product guaranteed?
A: We ensure wear resistance and long service life by selecting high-quality brass, optimizing production processes (such as precision turning and surface polishing), and conducting rigorous quality inspections.
Q: Are your brass bushings suitable for high-temperature, humid, or corrosive environments?
A: If customers require use in high-temperature (200-300°C), high-humidity, or mildly corrosive environments, we offer surface plating (such as nickel or chrome) or special brass alloys (such as tin brass) to enhance their high-temperature and corrosion resistance.
