Precision CNC Machined Bronze Bushings | Custom Large Diameter Slide Bearings

Hongxin Precision specializes in the custom machining of high-precision copper alloy bushings and sliding bearings, dedicated to providing highly reliable rotary support components for heavy machinery and high-load equipment. Leveraging advanced CNC turning equipment and mature machining processes, we efficiently manufacture large-diameter, high-precision bushings, ensuring exceptional wear resistance and extended service life even under conditions involving heavy loads, severe impact, and complex operating environments.

• Diverse Range of High-Performance Copper Alloy Materials
  We carefully select premium materials—including aluminum bronze, high-strength brass, and tin bronze—to provide optimal solutions tailored to the specific requirements of various operating conditions. These materials exhibit superior wear resistance, self-lubricating properties, and anti-galling capabilities, ensuring stable operation in environments characterized by heavy loads and low-speed, high-stress conditions.
• Precision Machining Capabilities for Internal Oil Grooves
  We support the high-precision machining of various complex lubrication structures, including straight, spiral, and figure-eight-shaped oil grooves. By optimizing the design of lubrication pathways, we effectively reduce friction coefficients and operating temperatures, thereby significantly enhancing equipment operational efficiency and extending maintenance intervals.
• Stable Control for Large-Sized, Thin-Walled Structures
  To address the inherent challenge of deformation during the machining of large-diameter, thin-walled bushings, Hongxin Precision employs a multi-stage stress relief and precision finishing process. This approach ensures uniform wall thickness while achieving high-precision control over critical geometric tolerances—such as roundness and cylindricity—thereby guaranteeing assembly stability.
• Comprehensive Performance Testing and Quality Assurance
  Prior to shipment, all bushing products undergo rigorous hardness testing and surface roughness inspections, supported by high-precision metrology equipment to generate comprehensive inspection reports. Through thorough verification of critical dimensions and fit tolerances, we ensure a high degree of compatibility between our products and the equipment's main spindle, guaranteeing long-term, stable operation.
