**Brand**: VULKAN
**Model**: VULASTIK‑L4316
VULKAN VULASTIK‑L4316 belongs to VULASTIK‑L series axial plug‑in highly‑flexible rubber coupling, designed for diesel‑engine‑driven powertrains for marine and stationary power generation. It adopts proven external toothing plug‑in construction; the elastomer disc element can be assembled and replaced axially without disassembling adjacent equipment, greatly reducing ship‑repair and on‑site maintenance downtime.
It provides excellent torsional‑vibration damping and shock‑absorbing performance, compensates axial, radial and angular shaft misalignment, lowering extra stress to bearings, shafts and gear‑boxes. Two elastomer material options are selectable: Natural Rubber (NR) for general marine duty; Silicone compound for high‑temperature, oil‑resistant working conditions. Maintenance‑free running, no lubrication required during service life.
