    You spin me right round(01/07/2019)

    Slewing ring bearings have been in use for many years and are often associated for rotating heavy and slow-turning or slow-oscillating loads on a horizontal platform, such as on a crane. In this article, however, dry-tech director, Robert Dumayne, focuses on the ‘Lazy Susan’ type of slewing ring bearings for fast rotary movements in confined spaces.

    The ubiquitous spring deserves more attention than it’s given(03/05/2019)

    Choosing a spring from a catalogue may seem like an easy answer, especially if it offers the cheapest option. Not so, argues Emma Burgon, Engineering Director at William Hughes, who maintains that selecting a spring purely on grounds of cost can prove a false economy, especially when production line inefficiencies are taken into consideration.
