JS650 High Hardness Oil Free Bushing - 650 Hardness Rating, 2x Wear Resistance for Automotive & Industrial Applications
JS650 high-hardness oil-free bushings represent an advanced solid lubricant bearing solution with superior performance characteristics compared to standard MQ090/092 models. Engineered for demanding industrial applications, these bushings deliver exceptional durability and maintenance-free operation.
| Hardness Level | 650 (Twice standard copper hardness) |
| Wear Resistance | 2x higher than standard bearings |
| Lubrication Type | Solid lubricant (Graphite/MoS2) |
| Base Material | High-brass substrate |
- No oil installations required - eliminates filling hole processing costs
- Significantly reduced operating costs through minimal maintenance
- Extended service life with superior wear resistance
- Environmentally friendly - no waste oil recycling needed
- Simplified mechanical design and reduced assembly complexity
JS650 bushings are engineered for high-performance applications including:
- Metallurgical casting equipment
- Rail transport systems and train stents
- Heavy-duty rolling machinery
- Mining equipment operations
- Marine vessel components
- Gas turbine systems
Ideal for high-temperature, high-load, and low-speed operating conditions where traditional lubrication methods are insufficient.
The solid lubricant embedded in the high-brass base generates optimal lubrication conditions through friction heat, creating an oil-powder coexistence that protects shafts from wear while maintaining permanent lubrication characteristics.
