Reliability, even in the harshest of conditions. Circlips in heavy machinery.

Heavy machinery needs to satisfy exacting demands. It needs to offer fail-safe reliability and help stem the pressure of time that is so common in the construction industry. What's more, the modern-day building site is smart, digital and efficient. And sustainable, of course. This requires a level of professionalism that industry partners also need to command. 

Cirteq is outstandingly skilled in the development and manufacture of circlips and retaining rings.
Our products can be found in every major manufacturer's heavy machinery and in a wide variety of applications. Mountings, shafts, transmissions, steering columns, axles, brake systems, engines, pumps, or mining and road construction: our long-lasting products provide the safety you need and help minimise downtimes.

A broad selection of DIN 471 and DIN 472 certified circlips, DIN 5417 certified retaining rings,
DIN 6799 certified circlips and DIN 988 certified shims and support washers ensures that numerous applications can be fulfilled simply through our standard range. While for more demanding needs, we work hand in hand with you to develop bespoke, custom-built solutions.

Premium quality is another hallmark of what we deliver at Cirteq. We meet and surpass our customers' requirements. When it comes to the residual dirt regulation, for example: on our testing stations, we monitor whether the maximum particle sizes, volumes and weight are within the range of compliance. What's more, we are accredited to IATF 16949:2016, ISO 14001 and ISO 45001 and receive exceptional audit results from our customers.
