Brass Graphite Sleeve Bearing,1pc Inner Diameter 80mm Oil-Free Self-lubricating, Outer 90~100mm, Height 30~150mm JDB Bushing(80x100x110mm)

Material and ProcessHigh-strength brass alloy: contains embedded graphite particles, which has self-lubricating effect and can reduce friction and wear.High temperature resistance: operating temperature range: -20°C to +250°C, up to 300°C in a short time.Corrosion resistance: resistant to water, steam and weak acid and alkali environment.Easy to install: no additional lubrication groove is required, it can be directly pressed in or bonded.Parameters:Material: graphite brass (CuZn24Al6)Hardness: HB 60-80Density: 8.5 g/cm³PV value: 2.5 MPa·m/s (dry friction)Application ScenariosIndustrial machinery: conveyors, pumps and valves, gearboxes, hydraulic equipmentAutomotive industry: suspension systems, steering mechanisms, chassis bushingsAgricultural machinery: tractors, harvester bearing partsMarine/construction machinery: steering gears, excavator spherical bearingsFood/packaging equipment: occasions requiring oil-free lubrication

• Self-lubricating and Maintenance-free: copper alloy + embedded graphite design is adopted, and the lubrication layer is automatically released during operation to reduce friction and wear. It is suitable for occasions where frequent refueling is not possible
• Size Description: Inner Diameter 80mm ; Outer Diameter 30~100mm ; Height 30~150mm
• Precise Size and Easy Installation: precision production, tolerance control at H7 level, ensure perfect fit with shaft parts, reduce vibration and noise, compatible with most shaft diameters, and easy installation
• Corrosion Resistance: water-resistant, steam-resistant and weak acid and alkali environments, suitable for humid, dusty or mildly corrosive working conditions, such as agricultural machinery, ships, industrial equipment, etc.
• Please check the size carefully before ordering
