Technical Information
Material Composition
The solid casting bronze material is engineered for highly demanding applications in challenging environments. Our standard assortment includes plain sleeve bushings, flanged bushings, and sliding plates conforming to ISO 4379 and DIN1850 standards.
The solid bronze body features drilled holes filled with solid graphite lubricant, enabling reliable operation in oilless environments. Alternatively, machined oil grooves and holes can be added for enhanced lubrication when using grease.
Performance Advantages
- Insensitive to dirty and contaminated environments
- Resistant to shock loads and vibrations at slow speeds
- Compatible with poor shaft surface finishes
- Good resistance to corrosive conditions
Material Specifications
Solid bronze bushings and plates are manufactured entirely from tin bronze (CuSn10P), offering excellent machinability. All surfaces are precision machined for optimal performance. Solid iron alternatives are available for cost-sensitive applications with lower performance requirements.
Industry Applications
- Construction machinery
- Transport equipment
- Pulp and papermaking machinery
- Off-shore equipment
