No matter what size the order, KTR Corporation will make every effort to ensure that our products are processed, packaged and shipped to exceed customer expectations. Every KTR team member is trained to put the customer first. It is the direct responsibility of each and every department to make sure that

KTR manufactures a wide variety of couplings for the motor and power transmission industry. In business for over 40 years they are a recognized leader in quality and design for couplings for all types of applications. If you require zero backlash, non-lubricated, or any type of coupling KTR can supply these high quality couplings from stock.

Features of primary coupling groups:

Rotex

ROTEX couplings are characterized by small dimensions, low weight and low mass moments of inertia yet transmit high torques. Running quality and service life of the coupling are improved by accurate all-over machining.

Their application is ideal for transmitting torque while damping torsional vibrations and absorbing shocks produced by the uneven operation of certain prime movers.

• Shaft coupling for torque transmission and damping of torsional vibrations
• Axial plug-in - easy assembly - maintenance free
• Operative range from -40ºC to +100ºC, peak temperature up to +120ºC
• Compensation for axial, radial and angular shaft misalignments
• large base programme from stock:
        finish bore acc. to ISO fit H7 and feather key groove acc.
        to DIN 6885 sheet 1-JS9
       spline toothings acc. to DIN and SAE
       inch and taper bores
• Explosion protection rated and confirmed acc. to EG Directive 94/9/EG

Radex

The RADEX-N is a backlash-free, torsionally rigid and maintenance-free all-steel coupling. The laminae that are extremely rigid in sense of rotation are made from high-strength, stainless spring steel and enable a compensation for high displacements with low restoring forces. By reason of the all-steel design the RADEX-N can be used in drives with temperatures of up to 280 °C.

• Single cardanic design   
• Only angular and axial misalignment permitted   
• High torsional stiffness   
• Compact design   
• Application areas   
• Mixers   
• Agitators   
• Immersion pumps   
• Fans   
• Applications with high radial load

Bowex

BoWex Curved-tooth gear couplings® are flexible shaft connections for a positive torque transmission and specifically suitable to compensate for axial, radial and angular shaft misalignment.

According to the well-known effect of curved-tooth gear couplings any edge pressure in the spline in case of angular and radial displacements is avoided so that BoWex couplings are almost free from wear.

• Curved tooth plug-in coupling (two-part) made from nylon   
• Maintenance-free due to material combination nylon   
• Compensation for shaft misalignment; axial - radial - angular   
• Low own weight as well as low flywheel torques   
• Axial plug-in - easy assembly   
• Operative range -25°C to +100°C   
• Available from stock with finish bore for standard shafts   
• Including feather keyway according to DIN 6885 page 1 and thread for setscrew   
• Tolerance of the bore + 0.05 - 0.1 feather keyway ± 0.08

Minex-S

The MINEX-S is a permanent-magnetic synchronous coupling that transmits torque through magnetic forces between the internal and the external rotor.

It ensures a hermetic separation of the drive and the driven side in its main function as sealing element in pumps and agitators. For critical media like aggressive acids etc. it serves as a reliable seal and prevents serious leakages occurring.

On request KTR can manufacture special customer-specific types of the MINEX-S in connection with KTR hydraulic components. Thus existing pumps with a conventional shaft seal can be easily retrofitted with the MINEX-S.

• Permanent magnet coupling   
• Contactless torque transmission    ·
• Available from stock with pre-bored inner rotor and unbored outer rotor   
• Connection shaft to shaft   
• Finish bore available on request according to ISO fit  H7,   
• Feather keyway acc. to DIN 6885, page 1 - JS9   
• Containment shroud made of stainless steel 1.4571   
• Torque range from 0.15 up to 14 Nm

Poly – Norm

The POLY-NORM coupling is a torsionally flexible, shear type shaft coupling. It has an axial plug-in design with a unique short over all length. The POLY-NORM® can be used in nearly all types of machinery and is ideal for the pump industry.

The POLY-NORM coupling compensates for shaft misalignment of all kinds and safely transmits the torque.

• Shaft coupling for torque transmission and damping of torsional vibrations   
• Axial plug-in - easy assembly - maintenance free   
• Particularly small mounting length - for small shaft distance dimensions   
• Operative range from - 30 °C to + 80 °C  peak temperature of up to + 120ºC   
• Compensation for axial, radial and angular shaft misalignments   
• Use in general machinery
• Explosion protection rated and confirmed acc. to EG Directive 94/0/EG
