Back to the future for electric speed record

04/12/2023

The current development of electrically powered vehicles is a big part of today’s alternative sustainable energy revolution. Whilst most attention is focused on the ‘here and now’ and the future, it’s interesting to look back at some important milestones and highlights as we move inexorably towards greener, more sustainable solutions.

Passing the acid test: igubal bearing saves battery recycler thousands

28/11/2023

Simply switching to a polymer bearing from a stainless steel bearing has saved a lead acid battery recycler, Fry’s Metals thousands in maintenance costs, and far more in preventing lost production time.

Why are there so many types of precision coupling?

04/10/2023

Where two rotating shafts require a connection, you’ll find a coupling. From large industrial powertrains down to small devices – couplings used across industry are varied in design. Even for the highly precise couplings common in motion control applications, there is a plethora of options. But why are there so many precision couplings? David Lockett, Managing Director at Huco, explains.

Medical wave springs: Designing with size in mind

02/08/2023

Medical device engineers strive for compact designs for a variety of reasons, such as portability, enhanced patient comfort, and increased efficiency. In many cases, a compact design requires compact components. To help designers to optimise the size of their devices, Simon Ward, Technical Manager of TFC, highlights the capabilities of wave springs.

Selecting the right wave spring end type
