Product Overview
JFFB split graphite bronze bushing (open C-type half bearing) is a split self-lubricating sliding bearing made of high-strength brass / cast bronze matrix with embedded solid graphite lubricant plugs. The split open design allows easy installation and replacement without disassembling the whole shaft assembly. Graphite solid lubricants work continuously under high temperature and heavy load, realizing oil-free or less-oil operation. It greatly reduces maintenance frequency and downtime, widely used in heavy machinery, hydraulic cylinders, mold equipment, construction machinery, automation equipment.
Key Features
✅ Split C-type Open Structure: Convenient mounting & maintenance, suitable for shafts that cannot be fully disassembled
✅ Solid Graphite Embedded Lubrication: Self-lubricating performance, works well under high load, low speed, high temperature
✅ High Strength Bronze Substrate: Excellent wear resistance, shock resistance and high load capacity
✅ Wide Temperature Adaptation: Operate reliably from low temperature up to 300℃
✅ Customizable Dimensions: Support OEM & ODM, custom inner diameter, outer diameter, length, flange size
✅ Low Friction Coefficient: Stable friction performance, reduce shaft wear and noise
Application Scenarios
- Construction machinery: Excavator boom, arm hinge points
- Hydraulic equipment: Hydraulic cylinder guide bushing
- Molds & Injection molding machines
- Automation equipment, packaging & textile machinery
- Machine tools, mining equipment, heavy-duty conveyors
