GEARex® couplings are an all-steel design offer flexible compensation for axial, radial and angular shaft displacement.
Small dimensions and light weight, along with a small mass moment of inertia, results in a wide range of applications for GEARex® couplings. Numerous coupling sizes to cover torque transmission from 930 Nm to 820.000 Nm with shaft dimensions up to a maximum of Ø 450 mm available. The GEARex® design also corresponds with AGMA standards (American Gear Manufacturer Association).
GEARex® couplings are used in every range of general engineering that require high operating safety and a long service life provided by the reliable grease lubrication of the crowned spline. Pressure in the spline is avoided in case of angular and radial displacements while permanent grease lubrication also produces a better friction ratio of the spline with an operation almost free from wear along with a long service life of the coupling.
GEARex® couplings are suitable for power transmission in drives used in hazardous areas. They are certified according to EC standard 94/9/EC (ATEX95) as units of category 2G/2D, therefore are suitable for use in hazardous zone areas 1, 2, 21 and 22.
With a presence in Bahrain KTR Couplings can offer a technical design support and maintenance support services. This means we can offer a level of service for replacement parts and design support that our competitors cannot. In fact, KTR has a truly international reach from which to support your business – 24 dedicated global subsidiary offices and a sales presence in over 60 countries worldwide. This is another reason why international businesses choose KTR Couplings.
At KTR Couplings we understand that component failure costs far more than the value of the component replacement. Some failures can lead to protracted system down-time that causes a significant loss to the business. So overall the cost of the component is a very small consideration and the use of more expensive components which provide higher performance, improved reliability and longer life can in fact save your business money.
Bow thrusters, rear rudders and transverse rudders require couplings, that dampen torsional vibrations, such as ROTEX®. This type of coupling functions without any maintenance, and ROTEX® compensates for axial, radial and angular displacements, increasing the service life of the entire drive system. Its damping effect can be controlled by the Shore hardness of the elastomer spider.
Our couplings offer:
KTR also offers arrange of marine OAC coolers featuring IP56 motors. These marine OACs are treated with a KTL corrosion resistant coating to combat the effects of working in a saltwater environment common to on-deck and other marine applications.
KTR offer range of flexible and torsionally stiff couplings well to handling misalignment and vibration involved in pump and compressor applications. Steel laminae couplings, RADEX® and RIGIFLEX®, work well in difficult ambient conditions and can also be supplied with highly stiff glass or carbon fibre spacers for bridging large shaft distances. KTR’s RIGIFLEX® couplings also correspond to API 610 and 671 regulations, and are ATEX certified. The new RIGIFLEX® HP (high power) design has been specifically developed to work at high speeds (up to 13,000 rpm) with applications such as turbo compressors and the compression or liquefaction of natural gas.
KTR can also offer large pin & bush coupling REVOLEX® for pump applications if requested.
KTR’s GEARex® and REVOLEX® couplings have your high power applications covered (1,050,000 and 488,000 Ton respectively) – including aluminium smelting plants, steel rolling mills, cement plants and various mining applications. KTR’s GEARexÂ couplings feature small dimensions and yet a high power density and are in accordance with AGMA standards (American Gear Manufacturers Association).
