1: CENTAFLEX SERIES - A
Highly flexible, free of backlash and wear, electrically insulated, numerous special designs for generators, pumps, compressors, boats and universal joint shafts. Can be disconnected by removal of radial screws to check motor directional rotation. Available with plain bore, spline or taperbrush. Available in 15 sizes for torques from 10 to 14 000 Nm.

2: CENTAFLEX SERIES - B
For connection of 2 shafts in all areas of machine drives. Flexible element can be replaced without disturbing shaft alignment. Available in 7 sizes for torques from 10 up to 2 800 Nm.

3: CENTAFLEX SERIES - E
Identical to type D, extremely robust heavy duty, compact yet simple shaft to shaft "fail-safe" coupling which dampens vibration and shock loads and accepts axial, angular and radial misalignment - 10 sizes for torques from 75 to 350 000 Nm, max. bore 220mm.

4: CENTAFLEX SERIES - x
Torsionally stiff coupling, free from play. Flexible in angular and axial directions. Oil and temperature resistant up to 150°C.

DIESEL ENGINE COUPLINGS
5: CENTAFLEX SERIES - H

Torsionally stiff, compact, oil-resistant, maintenance free, noise-less polyester elastomer coupling, specially developed for diesel engine - hydrostatic pump drives with high thermal stability on the engine flywheel and are supplied with Centaloc backlash-free hubs employing a patent locking system, splinted hubs to suit all pumps and hydraulic motors available from stock. Available in 9 sizes for torques up to 4 000 Nm.

6: CENTAMAX
Torsionally high elastic coupling enabling critical speeds to be kept far enough below engine idling speed permitting utisilastion of the entire engine working speed range. Available in 16 sizes for torques up to 15 000 Nm.

7: CENTAFLEX SERIES - D
This range was purpose designed for diesel driven generator sets and other similar drives, simple robust blind-fitting design with flanges to SAE J620 and non-standard specifications to suit non-standard flywheels. Simple installation, available in 7 sizes for torques fro 600 to 40 000 Nm, max. bore 220 mm.

8: CENTAFLEX - K
Torsionally stiff coupling designed to drive hydraulic pumps and similar equipment having low moment of inertias. Compact, light oil and temperature resistant (-40°C - 150°C).

9: CENTAFLEX - V
Torsionally soft, intermediate maintenance-free coupling for universal joint shafts. Driving from diesel engine to a driven unit, shielding dangerous resonances below the engine operating speed range. Also has high dampening capability.

10: CENTAFLEX SERIES - R
Simple robust roller coupling with a progressive torsional charachterestic. Ideal for boat drives, providing very low stiffness at low torque and speed which shifts the torsional resonance below idling speed.

11: CENTAFLEX-L-G-M-DP MARINE COUPLINGS
Main propulsion couplings for larger boats and ships. Torque up to 600 kNm.
