Disc coupling NER series

compactlargeshaft

This is a compact flex coupling with outstanding large capacity. The NER series is a new ECHT-FLEX coupling that achieves overwhelming torque increase and compactness through ​the optimization of newly developed discs and bolts. ・Applicable shaft diameter: Φ25mm to Φ145mm Torque range: 590 to 8500 Nm Features ・Large transmission force The new disc shape has resulted in a significant increase in torque compared to the previous series. ・Outstanding ease of use Our unique center unit structure, which integrates the disk and spacer, eliminates the need for cumbersome disk assembly work on-site. Installation and removal is simply by removing and attaching the bolts between the center unit and the hub. ・Compatible with large shaft hole diameters By adopting a center unit, the maximum shaft hole diameter can be made larger than in the previous series. ・Wide range of options available A wide range of combinations are possible, including CFRP (carbon fiber reinforced plastic) spacers, shaft fastening with Power-Lock, and flange mounting. ・Non-backlash・Lubrication-free・Long life It has no backlash and high torsional rigidity, making it suitable for servo motor positioning devices. Shaft fastening method ・Key fastening *It can also be combined with Power-Lock KE series, etc. Please contact us for details. Long spacer - Hub end face distance (J dimension) up to 6m We can manufacture to your desired dimensions. ・Can be used with a floating shaft A floating shaft can be used when there is a distance between devices. ・Composite spacer We offer long spacers made of lightweight, corrosion-resistant CFRP (carbon fiber reinforced plastic).
