Centaflex 4AS coupling CF-A-004-0-S-50 is a torsionally soft OEM elastic coupling developed by CENTA Germany for micro-mechanical and compact automation systems requiring vibration isolation, alignment tolerance, and long-term reliability.
Its Type 0-S (pin connection) allows controlled axial float, reducing assembly stress and simplifying maintenance in confined layouts.
The 50 Shore natural-rubber compound provides exceptional damping and flexibility, protecting sensitive components and ensuring stable performance even at high speed.
