Round Flange Bronze Bushing Flanged Copper Bearing Self Lubricating Brass Bushing for CNC Automation Machinery
Product Overview
Our Round Flange Bronze Bushing is a one-piece flanged copper sleeve made of high-strength bronze alloy. Integrated flange design with 4 mounting holes for easy installation and axial positioning. It features excellent self-lubricating, wear resistance, high load capacity and low friction performance. Ideal for applications where oil refueling is inconvenient or maintenance-free operation is required. Widely used in CNC machines, automation equipment, packaging machinery, textile machines, hydraulic systems and mold equipment.
Key Features
✅ Integrated Round Flange: 4 mounting holes, simple assembly, effective anti-offset and axial positioning.
✅ Premium Bronze Alloy Material: High tensile strength, shock resistance, good thermal conductivity.
✅ Superior Wear & Friction Performance: Low friction coefficient, stable operation under heavy load.
✅ Maintenance Free Self-lubricating Design: Reduce lubrication frequency, adapt to intermittent motion & high temperature working conditions.
✅ Precision CNC Machining: Fine inner hole surface finish, strict tolerance control, interchangeable with standard OFG61/SHTZ series.
✅ Customization Available: Support custom inner diameter, outer diameter, length, flange size & special machining per drawings.
Application Scenarios
CNC machine tools, injection molds, automation linear units, packaging & textile machinery, hydraulic cylinders, robotic equipment, food machinery, general industrial mechanical transmission systems.
