NARA Torsionally Stiff Couplings – PANFLEX, GEAR, DRUM
- PANFLEX: lubrication-free disc packs, zero backlash, torsionally stiff
- GEAR: grease-lubricated, compact and light for the power transmitted
- DRUM: wear indicator for overhaul timing; surface treatment and sealing for port environments (humidity, salt, dust)
- NARA (Korea) products – supplied and quoted by FEYANA
NARA torsionally stiff couplings transmit high torque precisely even under severe operating conditions and extreme temperatures. Three families: PANFLEX disc couplings, GEAR couplings and DRUM couplings for cranes.
FEYANA supplies products of NARA Autosys (Korea), a power-transmission manufacturer founded in 1977 in Busan and certified to ISO 9001, ISO 14001 and ISO 45001.
Product range
| Series / model | Description |
|---|---|
| PANFLEX NPA / NPB / NPS / NPE | Disc couplings: NPA compact single element; NPB double element, API 671, assembled without moving connected equipment; NPS customisable spacer; NPE with adapters, extended bore |
| PANFLEX NPC | Corrosion-resistant composite spacer, lightweight, for long shaft distances – cooling towers |
| PANFLEX NPH | High-speed precision balanced, API 671, optional ATEX (2014/34/EU) |
| GEAR – G series (NGG, NGA, NGE, NGGB/NGGD) | Gear couplings: two hubs/two sleeves; spacer type; one hub/one sleeve; with brake drum / disc |
| GEAR – S series (SSM, SEM, SVM, SAM) | Gear couplings: two hubs; gear hub + rigid hub; vertical; spacer type |
| GEAR – RWS / RW | Gear couplings for railway vehicles, high angular and offset capacity, low noise and vibration at high speed |
| DRUM – DR series | Drum couplings for container crane rope drums with heavy vertical loads; crowned rollers compensate parallel, angular and axial misalignment |
