Product Description
Oiles Graphite Plugged Bronze Bearing - Self-Lubricating Design
High-strength centrifugal cast bronze with graphite-filled plugs for reliable dry or lubricated operation in demanding industrial applications.
Product Overview
The Oiles #500 graphite plugged bronze bearing features a blind hole design with self-lubricating properties. Manufactured using centrifugal casting of high-strength brass alloy (CuZn25Al6Fe3Mn3) with graphite-filled plugs, this bearing provides exceptional performance without external lubrication systems.
Material Specifications
Base Material
CuZn25Al6Fe3Mn3 (Manganese Bronze) with graphite plugs
Alternative Materials Available
- PTFE or SL4 lubricant variants upon request
- CuSn5Zn5Pb5, CuSn7Zn7Pb4, CuSn12 alloys available for custom requirements
Key Features & Benefits
- Cost-effective solution with higher crash strength than standard bronze graphite bearings
- Self-lubricating design: Graphite releases through frictional heat, creating optimal oil-powder lubrication that protects shafts and extends service life
- Internal graphite-only surface configuration for specialized applications
- Maximum operating temperature range: -40°C to +300°C
Available Configurations
- Cylindrical Oiles Bushings
- Flanged Oiles Bushings
- Thrust Washers
- Slide Plates
- Spherical Oiles Bearings
- Custom designs according to specific requirements
