The RIGIFLEX-HP steel laminae couplings (High-performance coupling) are used for severely high-speed drives with a circumferential speed of up to 200 m/s. The special properties of this coupling type are smooth running even with the highest speeds and the weight-optimized design. Due to the low coupling weight of these steel laminae couplings, the loads on […]

ROTEX ZRS jaw coupling for bridging smaller and larger shaft distances The lightweight type ZRS made of high-strength aluminum impresses by very high overall stiffness. The high stiffness of the aluminum pipe results from the design; here two pipes combined via webs – the ROTEX cams – are concerned. There is a positive impact on the […]

The bearing of the joint heads is made by plain bearings with joints type X and XD limiting the maximum permissible speed to 300 rpm. The maximum diffraction angle per joint is 45°. The precision joints type X and XD are made of stainless steel and thus corrosion-resistant. Precision joints in an extendable version are […]

In case of overload the KTR-SI FRA overload couplings uncouple driving and driven side while protecting the drive train from damages. After eliminating the overload the KTR-SI FRA can automatically be re-engaged by reversing the direction of rotation for a short time. As a result, this version is optimally suitable for positions difficult to access. […]

Clamping Nuts for secure all-round clamping force With KTR’s clamping nuts large screw connections can be easily pretensioned by hand (use of common dynamometric screwdrivers up to approx. 100 Nm). Our clamping nuts are used as mechanical force-transmitting elements for reliable connections with high axial force and minimal power input. Features: * Use of common […]

The magnetic couplings of the MINEX range are permanent-magnetic couplings transmitting the torque without contact through magnetic forces between two magnetic rotors. The standard type MINEX-S with containment shroud and magnets positioned radially ensures hermetic separation of driving and driven side in pumps and agitators. As a hysteresis coupling version, it is in turn suitable […]

KTR SINULASTIC is a modularly structured series of highly flexible flange couplings based on a disk-shaped coupling body. Four practical basic versions with individual properties cover a wide range of applications primarily for diesel engine drives, but also general drive tasks. Applications of the highly flexible flange coupling SINULASTIC: The main task of the coupling […]

KTR precision joints consist of a joint center piece and two hubs that are interlinked by straps. The bearing of the joint heads is made by plain bearings with precision joints type G and GD. The plain bearings type G and GD limit the maximum permissible speed to 1,000 rpm. The maximum diffraction angle of KTR’s […]

KTR has developed a new all-purpose coupling for use in a broad range of applications from main to auxiliary drives in construction equipment and general industry. The zero-backlash and torsionally soft EVOLASTIC is available in ten base sizes and with variants in between covering nominal torques from 100 to 5,600 Nm. Spacers for large DBSE (distance between shaft ends) […]

Pumps and compressors make up about one-third of energy consumption in industry. Consequently, the market is big with the portfolio ranging from miniature laboratory pumps to large-scale plants for petrochemistry. An essential function of the coupling is the ability to compensate for displacements in the drive train. That is why double-cardanic couplings are often used. […]

As a manufacturer of couplings with over 60 years of innovation, KTR is always seeking to improve on existing designs. Split-hub designs, such as the machined steel type ROTEX A-H, have been a part of KTR’s offering for decades. However, with industry demands for new efficiencies and cost savings ever-increasing, KTR has expanded the split-hub […]

The REVOLEX KX-D SPLIT consists of hub bodies separated into two halves. This production procedure allows for radial assembly and disassembly of the torsionally flexible pin & bush coupling without dismounting driving and driven side. The coupling is screwed via block assembly. Material: steel Sizes: 150 to 355 Torques (TKN): 25,000 to 350,000 Nm Radial […]

Even if the wind power industry is a growth sector now as before, the manufacturers are under fierce competition and cost pressure. The index of  “Cost of energy“ is decisive, i. e. the ratio of operating expenses to energy yield. This calculation includes the level of efficiency, availability and maintenance effort. This means for the […]

Gensets take over a vital function as emergency power generators in infrastructure facilities such as hospitals and computer centers, whereas gensets often form the only technology for power generation in areas with no electricity grid. From the point of view of the design engineer of these plants coupling the I. C.-engine to a generator is […]

The sustained concentration in shipbuilding resulted in establishing very large shipyards acting internationally. Apart from that there are highly specialized suppliers for individual markets such as work boats, leisure boats and yachts. Freight rates, international trade and the oil price are central parameters for the economic situation of the overall industry which has a significant […]
