Product Description
Overview
Our JF-800F flanged bimetal bushing is a high-performance composite sliding bearing, engineered by sintering copper alloy onto a low-carbon steel backing. The integrated flange structure can bear both radial and axial loads simultaneously. Precisely machined oil holes and oil grooves are reserved for grease lubrication. With a split notch design for convenient assembly, this bushing delivers outstanding wear resistance and load capacity for heavy-duty industrial sliding applications.
Structure & Material
- Base layer: Low carbon steel, provides high mechanical strength and impact resistance
- Friction layer: Sintered copper alloy CuPb10Sn10 / CuSn6Zn6Pb3 (optional), low friction and excellent anti-wear property
- Built-in flange shoulder for axial positioning
- Pre-machined oil holes & oil grooves for stable lubrication
- Split notch design for easy mounting
