Product Description
1. Product Overview
Our JF800 bi-metallic bushing is manufactured by powder metallurgy sintering technology. It combines a high-strength low-carbon steel backing and sintered bronze alloy inner layer. The steel and bronze are tightly bonded through metallurgical reaction, avoiding layer separation under heavy load and impact.
This bi-metal bearing sleeve features high load capacity, excellent wear resistance and stable friction performance. It is widely adopted in hydraulic cylinders, construction machinery, injection molding equipment, automotive chassis, automation lines and mining machines. Custom dimensions, oil holes and oil grooves are available for your unique engineering demands.
2. Core Advantages
✅ Heavy Load & Shock Resistance
High strength steel back supports heavy radial load, bronze lining absorbs impact force. Max static load up to 250 N/mm².
✅ Outstanding Wear Performance
Uniform sintered bronze layer, good anti-friction property, reduces shaft wear and extends service life.
✅ Stable Lubrication Design
Custom oil holes / oil grooves can be processed for circulating oil lubrication, suitable for continuous working conditions.
✅ Precision Machining
CNC turning & fine boring, strict tolerance control, surface roughness Ra ≤0.8μm, easy assembly.
✅ Customizable Size & Structure
ID, OD, length, flange, oil hole position all can be customized. Supports small batch & mass production.
✅ Quality Assurance
ISO9001 certified factory. Each bushing undergoes dimensional inspection and metallurgical test before shipment.
