Electrically insulated rolling bearings
Electrically insulated rolling bearings feature electrical insulation that is built into the bearing, providing reliable protection against current passage and electrical corrosion. Typical applications are electric motors, generators and other electrical machines. The Austrian manufacturer NKE Austria GmbH offers electrically insulated rolling bearings in several versions. In this article, Klaus Grissenberger, Application Engineer with NKE, explains the causes of passage of electrical current through rolling bearings, damage symptoms and countermeasures, properties and production processes of electrically insulated bearings.
Online guide to perimeter guarding for robots and robot cells
Jeremy Procter, a Member of standards committees ISO/TC 199/WG 6 (Safety distances and ergonomic aspects) and BSI MCE/3 (Safeguarding of machinery), and Managing Director of Procter Machine Guarding, outlines the requirements for guarding robots and robot cells.
Robotics in the fresh produce sector
Chris Sumner, MD of FANUC UK, considers why robotic uptake within the fresh produce segment has been lower than that in other manufacturing sectors.
Pump design and its effect on mine safety and efficiency
The technology involved in coal mining around the world has advanced a great deal over the years, especially in terms of improving the health and safety of the miners. At the same time mining efficiency and production rates have also improved. Pumps, in their many different designs, perform a large number of vital tasks within the mining industry and as such they can be responsible for certain aspects of mine safety. However, with so many pumps in operation they can also make a considerable contribution towards improving the efficiency of the mine, especially in terms of energy consumption.
CE marking: what buyers should look for to ensure machine safety
Derek Coulson, an independent machinery safety consultant with Safe Machine Ltd, outlines the requirements for CE marking and what buyers should look for.
Wear of rolling bearings: signs, causes & remedies
Wear of rolling bearings appears in many different forms. In this article, Dr Steve Lacey, Engineering Manager at Schaeffler UK, describes the principle types and causes of rolling bearing wear, as well as guidance on remedial action.
Adhesives and fasteners guide from WDS
One of the most common needs in engineering is to join two or more parts together. Usually, the main requirement is for a secure and long-lasting bond, although the ability to undo the joint at will is not uncommon. Here, John Marshall, Technical Engineer at WDS Component Parts reviews the relative merits of various fastener and adhesive options.
Brakes and clutches: the defining element
Brakes and clutches are often the defining element in the operation and productivity of driven machinery. However, they are frequently taken for granted, so here, Mike Hemming, Engineering Manager at Matrix International in Scotland redresses the balance.
