Bronze slide bearings provide good wear resistance, corrosion protection, and a naturally low friction coefficient. They are hollow cylindrical components, available with one, two, or no flanges, and are designed to extend and support rotating shafts in machinery of all sizes, from light-duty to heavy-duty and even extra-heavy-duty equipment. Made from copper-based alloys, these bearings minimize friction between moving parts and perform reliably under demanding or continuous working conditions. Their self-lubricating properties keep the bearing running smoothly, even when oil lubrication is limited, which helps reduce wear and maintenance frequency. Each bronze slide bearing is custom-made according to specific equipment requirements and intended applications, with micron-level precision that guarantees consistent quality and long service life.
Clients can choose among several bronze alloys, each selected based on performance needs and application type. Commonly used grades include C95400, C91700, and C83600, as they offer the right balance of strength, wear resistance, and stability.

Bronze slide bearings are used in a wide range of industries and operating conditions, including:
- Steelmaking equipment and rolling mills
- Power generation and hydroelectric turbines
- Mining machinery and heavy-duty industrial equipment
- Motors, cranes, and presses
- Forging machines and hydraulic systems
- Mining trucks and other large transport equipment
They can operate under extreme conditions such as heavy loads, high temperatures, impact, reciprocating motion, and limited lubrication.
