Product Description
Product Overview
This flanged graphite bronze bushing is a high-performance self-lubricating bearing made of high-strength tin bronze / high-lead bronze base, embedded with solid graphite lubricant dots. It eliminates the need for regular oil refueling, works reliably under heavy load, low-speed, high-temperature and impact working conditions. The integrated flange design provides axial positioning, widely adopted as guide sleeve for plastic molds, die casting molds, CNC machines, hydraulic cylinders and automation equipment.
Key Features
- Oil-free self-lubrication: Graphite solid lubricant embedded in bronze matrix, long service life, low friction coefficient.
- High load capacity: Bronze substrate with excellent compressive strength, good wear resistance, shock resistance.
- Flange locating design: Integrated flange for easy installation and axial anti-slip positioning.
- Wide temperature range: Stable performance from -40℃ to +300℃, suitable for high-temperature mold environment.
- Low noise & good dimensional stability: Precision CNC machining, fine surface finish, less deformation under load.
- Maintenance free: No frequent oil supply required, ideal for hard-to-reach lubrication positions.
Application Fields
- Injection molds, stamping dies, die-casting molds
- CNC machine tools, automation production equipment
- Hydraulic cylinders, engineering machinery
- Textile, packaging, food machinery
- Automotive, new energy equipment
