By Robert Taylor, product line manager, ARaymond U-nuts are self-retaining fasteners that provide an easy and fast attachment of mating panels. They will not turn as the screw is driven into place or freeze on screw threads. There’s no mathematical equation that will give you the answer to if and when a threaded fastener should be used in an application, but there are guidelines to follow for a...

For use in submersible pumps that handle cryogenic gases such as hydrogen and LNG, NSK has developed rolling bearings that do not require external lubrication. These stainless steel bearings with a cage made of self-lubricating fluoroplastic are seeing increasing adoption in submersible pumps from leading manufacturers. A growing number of projects worldwide are today promoting the use of hydro...

Thread stripping or shearing of threads is a common problem. Here Dr Bill Eccles – from Bolt Science – explains how thread stripping occurs and how the BOLTCALC program was recently used in a case study to solve a thread stripping problem. Thread stripping is gradual in nature and hence is not necessarily detectable at the time of assembly. For the threads to be fully sheared, a displacement of...

Constructing a new bridge in record time to replace the one that collapsed in Genoa in 2018 was a high profile project. All companies and suppliers were scrutinized as nothing was allowed to go wrong. Tragedy struck Genoa, north-western Italy, on the morning of August 14, 2018. During a torrential rainstorm, the city’s Ponte Morandi (Morandi Bridge) collapsed so suddenly that some thought it ha...

After two years of work by the TC20/SC4 committee, the new TORX® PARALOBE® ISO standards have been completed and published. Although the standards were created in the aerospace committee, the standards can be readily applied to applications in other industries.  These new ISO standards follow SAE standards AS8538 and AS8539 that were published in 2019. The new ISO standards’ titles are as follo...

Teijin Carbon Europe introduces a new carbon fibre thermoplastic unidirectional pre-impregnated tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost sensitive markets while offering the typical TPUD advantages such as high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability. Due to its flame retardan...

TesT has launched the next generation of Junker testing machines with transverse displacement amplitude control, enabling stimulation of the conditions in the field even more realistically. A bolted connection often bears a lot of responsibility eg. in railroad or aeronautical engineering. But what can it withstand and how long before it loosens? The Junker test has always been the preferred me...

Wilhelm Modersohn GmbH & Co KG, manufacturer of industrial components and fastening systems for concrete and masonry, is focusing its attention on the price development of stainless, acid and heat resistant steels... For some time now, Modersohn has been focusing on Lean Duplex steels, which are less volatile in terms of price. These are also currently cheaper and, due to their basic streng...
