CSB developed the CSB-26 and CSB-26E materials without PFAS
The CSB-26E complies with the PFSA regulations.
Material structure: Steel + porous bronze + polyamide
Metal-polymer self-lubricating bearings CSB-26 and CSB-26E are suitable for dry, oil or grease applications, including low speed and high loads.
The material has excellent resistance to wear, shock and chemical corrosion, as well as great dimensional stability. It meets the operating requirements under medium and high loads and offers resistance to impact and dust, especially for critical applications under high loads and for extended operation.
Comparative tests CSB-50, CSB-26 and CSB-26E
Specific pressure 50 MPa, rotation 20 rpm, dry, 4,000 cycles
Friction coefficient
