ATCORP, ATC-BM is a metallic composite material consisting of a steel strip as a supporting backing and a sintered-on, self-lubricating bronze sliding layer. The solid lubricant (graphite or PTFE) dispersed in the sliding layer under preload enables the sliding bearing to be used without the need for maintenance.The maintenance-free and self-lubricating material is available in different alloy variants and material thicknesses. The two-layer material structure enables the implementation of compact and highly resilient sliding bearing concepts that function reliably.ATC-BM properties include high static and dynamic load capacity, maintenance-free operation, a low Coefficient of friction, suitability for dusty and corrosive environments, and dimensional stability due to no water absorption. It is used in a wide range of applications where traditional lubrication is difficult or impossible, providing economic and reliable performance

Benefits of ATC-BM
ATC-BM normally requires no lubrication, enabling maintenance-free operation.
High Load Capacity: It can withstand high static and dynamic loads.
The solid lubricant within the bronze matrix provides a low Coefficient of friction, ensuring smooth, stick-slip-free operation.
It offers exceptional wear resistance, contributing to long service life.
Dimensional Stability: ATC-BM does not absorb water, ensuring high dimensional stability even when used in wet conditions.
It is suitable for use in dusty, corrosive, and even radioactive environments, with alloys available for specific applications.
The material is electrically conductive, preventing electrostatic charging.
