Introduction
As a manufacturer with over two decades of precision engineering experience, Anping County Boli Hardware Wiremesh Products Factory presents our premium Self-Lubricating Bronze Bushings, specifically designed for hydraulic cylinder pivot points. These bushings are engineered to deliver exceptional performance in demanding environments where continuous motion, heavy loads, and minimal maintenance are critical. Unlike traditional bronze bushings that require frequent greasing, our self-lubricating design incorporates solid lubricant pockets within the bronze matrix, ensuring consistent low friction throughout the service life. This innovation reduces downtime, lowers operating costs, and extends the lifespan of your hydraulic equipment. Available in inner diameters from 8mm to 50mm and fully customizable in outer diameter and length, these bushings offer a reliable solution for OEMs, hydraulic system integrators, and maintenance professionals worldwide.
Product Features & Benefits
- Self-Lubricating Technology: Embedded solid lubricants (graphite or MoS2) release gradually during operation, eliminating the need for external lubrication systems and reducing maintenance intervals.
- Superior Wear Resistance: The high-strength bronze alloy withstands heavy loads, shock, and misalignment typical in hydraulic cylinder pivot points, providing long service life even under cyclic stress.
- Low Friction Coefficient: The self-lubricating layer maintains a stable coefficient of friction (typically 0.06–0.15), ensuring smooth oscillation and reducing energy consumption.
- Corrosion & Chemical Resistance: Bronze naturally resists corrosion from moisture, hydraulic fluids, and mild chemicals, making it suitable for outdoor and industrial environments.
- Wide Temperature Range: Effective operation from -40°C to +300°C (-40°F to +572°F), accommodating extreme working conditions.
- Customizable Dimensions: Outer diameter and length can be tailored to your specific housing and stroke requirements, ensuring a perfect fit for your hydraulic cylinder design.
- Easy Installation: Precision-machined tolerances allow for press-fit or slip-fit installation without additional modifications.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between self-lubricating bronze bushings and regular bronze bushings?
A: Regular bronze bushings rely on external grease or oil for lubrication, while self-lubricating bushings have solid lubricant (e.g., graphite) embedded in the bronze matrix. This allows them to operate without external lubrication, reducing maintenance and contamination risks. -
Q: Can these bushings be used in high-temperature environments?
A: Yes, our self-lubricating bronze bushings are designed to operate effectively from -40°C to +300°C, making them suitable for most hydraulic applications including hot climates or near engine components. -
Q: Do you provide custom sizes beyond the 8mm–50mm ID range?
A: Yes, we can customize inner diameter, outer diameter, and length based on your drawings or specifications. Please contact our sales team with your specific requirements. -
Q: How do I install these bushings in a hydraulic cylinder pivot?
A: Installation is typically a press-fit into the housing bore. Ensure the bore is clean and within tolerance. The bushing can also be installed with a light interference fit. No additional lubrication is needed during installation. -
Q: What is the expected lifespan of these bushings?
A: Lifespan depends on load, speed, alignment, and environmental factors. In typical hydraulic cylinder pivot applications, they can last 2–5 times longer than standard bronze bushings due to the self-lubricating feature reducing wear. -
Q: Are these bushings compatible with biodegradable hydraulic fluids?
A: Yes, bronze is chemically compatible with most hydraulic fluids, including mineral oils, synthetic oils, and biodegradable fluids. However, for extreme chemical exposure, please consult our technical team. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 100 pcs. For custom sizes, MOQ may vary depending on dimensions and complexity. We offer flexible MOQ for samples and trial orders. -
Q: Can you provide samples before bulk order?
A: Yes, we offer sample orders. A sample fee and shipping cost apply, but we will deduct the sample fee from your first bulk order. Contact us for sample availability.
