Graphite Filled Bronze Bushes
APEX ALLOYS manufactures and exports graphite-filled bronze bushes for industrial applications where conventional greasing or oiling may be impractical. Embedded solid lubricant helps support smooth operation and reduced friction in demanding operating environments.
These bushes are used in automotive, heavy machinery, marine, aerospace, oil and gas applications. Standard and customized solutions are available, subject to dimensions, material specification and order requirements.
Product Overview
Graphite-filled bronze bushes combine a bronze alloy body with embedded solid lubricant. Product suitability depends on load, speed, temperature, operating environment and installation conditions.
