**Brand**: CENTA (Rexnord Group)
**Model**: CENTAMAX‑5000 (Size 5000, available in S / SB / SD / SCE variants)
**Origin**: Made in Germany
CENTAMAX‑5000 is a robust, plug‑in torsionally‑soft rubber‑in‑shear coupling, designed for resonance‑free operation of diesel‑engine‑driven powertrains in marine and stationary power‑generation applications. Torque is transmitted by interlocked toothed outer ring onto the rubber element. Self‑ventilated construction provides high permissible power loss, ideal for modern low‑emission engines. Multiple elastomer grades (Natural Rubber NR, Silicone Si, CENTALAN‑HT high‑temperature compound) are selectable to match system temperature and torsional‑vibration requirements. Backlash‑free transmission, maintenance‑free, blind axial assembly for quick installation and element replacementRexnord.
