Shaft Coupling ROTEX® By KTR

ROTEX Coupling is a maintenance free, axial plug-in, easy assembly curved jaw coupling.  It also compensates for axial, radial and angular shaft misalignments.  ROTEX has provided unmatched reliability and efficiency in the most demanding applications. 

Other features include:

• Vast selection of hub materials: Cast Aluminum, Cast Iron, Nodular Iron, Steel
• Urethane and Hytrel spiders
• Maintenance free and fail safe design
• Three hub designs, (regular,large,long) to fit your requirements
• Bore sizes up to 7.875 inches

• Standard Style Couplings - Cast aluminum hubs available up to size 28; Cast and nodular iron hubs available from size 38 to 180; Steel hubs available from size 19 to 90
• AFN and BFN Style Couplings - Perfect for heavy machinery; Allows radial disassembly without moving machine components; AFN allows spider replacement while coupling is installed; Flange materials: Machined Steel and Nodular Iron (See More Info for detail)
• CF, CFN, DF and DFN Style Couplings - Perfect for heavy machinery; CF and CFN connect flange to shaft; DF and DFN has double flange design to connect machine components, allow radial assembly without moving components and allow for quick spider replacement; Flange material: Nodular Iron (See More Info for detail)
• ZS-DKM-H Style Couplings - Assembly/disassembly through just 4 cap screws; compensates for high shaft misalignment; standard spacers up to 250mm shaft gap; reduces vibration and noise (See More Info for detail)
• Clamping Hub Style Couplings - Machined steel hubs; Statically balanced hubs; Axial plug-in, fail safe design
• A-H Style Couplings - Assembly/disassembly through just 4 cap screws; Easy spider changes without moving components (motor & pump); Reduces vibration and noise (See More Info for detail)
• Stainless Steel Style Couplings - Corrosion resistant; Ideal for Food Processing Machinery, Printing and Paper Equipment, Textile Machinery, Water Treatment Plants, Power Washing Equipment, Pharmaceutical Plants, Offshore Equipment and Military Applications (See More Info for detail)
• DKM and ZS-DMK-1 Style Couplings - Double cardanic design for extended shaft gap and parallel misalignment; Increased dampening capacity with double spiders; ZS-DKM1 center drop-out design allows easy parts replacement; machined aluminum center spacer (DKM).  (See More Info for detail).
• SD Style Couplings - Shiftable coupling design when stationary; Optional shifting linkage kit; Spring & Ball detent locking mechanism.  (See More Info for detail)
• ZWN and ZR Style Couplings - Connects shaft ends with extended shaft gaps; Compensates for high radial misalignment (See More Info for detail)
