Power supply in overhead cranes: energy chains vs. festoons

Reliable, dynamic cable management is one of the greatest challenges in modern crane technology.

The ubiquitous spring deserves more attention than it’s given

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.

What is bearing preload?

When assembling individual bearing components, the outer race, inner race, balls, and retainer all work together so that there is a controlled amount of internal clearance between the rings and balls.

A brief guide to spring design

Whether selecting a catalogue spring or specifying a custom item Chris Petts, M.D. at Lee Spring suggests that it is always worth considering the following factors:

Implementing condition monitoring can reduce the frequency and cost of equipment maintenance.
Pizza plant saves over €15,000 after switch to NSK bearings(11/03/2019)

A manufacturer of frozen pizzas was experiencing failures every four weeks on the belt tensioner serving one of its food conveyors.
Hybrid bearings: a developing technology(04/03/2019)

Hybrid bearings perform well under poorly lubricated and contaminated conditions. While they are much less prone to surface distress than their all-steel counterparts, imperfections that may pre-exist in the material or on the surface of a hybrid bearing’s ceramic rolling elements can potentially compromise performance.
Students learn from failure ready for 2019 Submarine Races(04/03/2019)

A team from the University of Southampton working on submarine technology is receiving engineer support and engineering-grade plastic bearings through the igus’ YES (Young Engineers Support) programme. The Southampton University Human Powered Submarine Society (SUHPS) is a group of students that design, build and test human-powered submarines to compete internationally.
Springing to the service of the manufacturing industry(18/12/2018)

With our centenary now upon us, Lee Spring is proud of our close to 100 year tradition and to reflect on the considerable growth in availability of springs and development in spring technology during that period.
