KTR is now offering its Minex-S magnetic couplings with containment shrouds made of the nylon material PEEK.

Until now, the standard types of this coupling have only been available with containment shrouds made of metallic or ceramic materials.

A disadvantage of metallic containment shrouds in rotating magnetic fields is the generation of eddy-current losses. PEEK polymer, however, is claimed to completely eliminate such losses.

Key benefits

  • PEEK polymer materials reduce selection torque by 10–15 per cent, as the eddy-current losses no longer have to be considered with the coupling selection.
  • These materials are particularly suitable for dry-running applications as the heat being generated by metallic containment shrouds as a result of eddy-current losses cannot be dissipated.
  • Containment shrouds made of PEEK do not generate any unintentional heat.

KTR Couplings

KTR is a German coupling manufacturer with over 50 years' experience providing power transmission products to a wide range of markets sectors including industrial pumps, construction, marine, hydraulics, rail, mining, machine tools, wind turbine technology and other renewable energy industries.

Since 1959 KTR has gone from being a relatively small manufacturer in Germany to having over 20 well-established subsidiaries around the world, making it one of the only coupling manufacturers in the world with its own global sales and service network, research and development facilities and in house engineering expertise.

KTR Couplings Ltd has specialised in the sale of power transmission products within the UK for over 10 years, offering over 30,000 different products available from stock representing 40 per cent of KTR’s total product range. The remaining 60 per cent of KTR output comes in the form of custom designs, manufactured to customer requirements, and one of the reasons why KTR is widely considered as the driving force behind the development of the worldwide coupling market and the production of world-class power transmission components. 

Other areas of expertise include hydraulic components — including bellhousings, damping elements, oil coolers, tank heaters and accessories; steel tanks — either standard off the shelf or bespoke tanks; torque limiters; torque measurement and clamping elements.
