Heavy Duty Rolled Tin Bronze Bushing FB092 Split Copper Sleeve With Oil Holes For Excavator Hydraulic Cylinder Hinge
【Section 1: Product Overview 】
FB092 wrapped bronze bushing is rolled from high-quality CuSn8P tin bronze strip, a cost-effective heavy-duty plain sliding bearing. The sliding surface is uniformly arranged with precision oil holes for lubricant storage. When the equipment starts running, an oil film can be quickly formed to reduce starting friction coefficient. Split seam design allows easy press-fit installation. It is manufactured according to standard, widely adopted for low-speed & heavy-load mechanical pivot joints.
【Section 2: Core Features 】
✅ Premium CuSn8P Tin Bronze Material High density rolled bronze strip, excellent wear resistance, impact resistance and corrosion resistance, stable performance under heavy shock load.
✅ Perforated Oil Hole Structure Evenly distributed oil pockets reserve grease/oil, maintain continuous lubrication, extend service life and reduce maintenance cycles.
✅ Rolled Split Design Split opening structure, simple press-fit assembly, saves machining cost compared with solid cast bronze bushing.
✅ High Load & Low Friction High static & dynamic load capacity, good dimensional stability, suitable for harsh dusty working environment.
✅ Custom Machining Available Custom inner diameter, outer diameter, length, oil hole layout. Flanged type is optional. OEM & ODM supported.
✅ Interchangeable with most mainstream bronze bushing brands.
