This filtration concept ensures that the filter clogs more slowly, reducing the pressure drop while retaining filtration efficiency. Ackerman points out that this combination technology solution developed by Atlas Copco was achieved without increasing the size of filter housings. The UD+ advanced filter technology is available at 20% less than the cost of the two-filter system and delivers a 40% lower pressure drop, removes contamination in compressed air down to 0.01 ppm, reduces maintenance costs and offers numerous environmental advantages. “Atlas Copco’s 2-in-1 nautilus concept is the ideal universal filtration solution for any reticulation line, setting a new benchmark in filtration standards for compressed air lines,” concludes Ackerman. Atlas Copco is a world-leading provider of sustainable productivity solutions. The Group serves customers with innovative compressors, vacuum solutions and air treatment systems, construction and mining equipment, power tools and assembly systems. Atlas Copco develops products and services focused on productivity, energy efficiency, safety and ergonomics.

The innovative anti-false brinelling grease for hub bearing units from SKF reduces friction and wear significantly, while improving bearing performance. SKF launched new grease that has been proven to reduce the damage caused by false brinelling in hub bearing units by more than 50 per cent when compared with competing greases. The lubricant has been introduced to the market to help overcome this wear phenomenon and can also enable overall improvements in vehicle efficiency by limiting fretting corrosion and the microdamages caused by vibration. Designed for use with both new designs and retrofits, the grease is fully compatible with bearing components materials and came out as the best performing lubricant for reducing the raceway microdamages caused by false brinelling when tested alongside several other standard greases. In particular, this solution was shown to lead to a consistent improvement in bearing robustness against the microdamages in the raceways that often occur during vehicle transportation by rail or truck, for example. In addition, the grease maintains the performance level of the hub bearing unit, including service life. Roberto Galante, Manager of Advanced Development Wheel End at SKF, said: “With the ability to cut false brinelling damage in half, this grease will play a vital role in helping OEMs to ensure that the microdamages caused by ball-raceway contact in hub bearing units during vehicle transportation will not exceed the strict thresholds specified by automotive companies. Furthermore, the lubricant maintains the same bearing qualities for consistently optimal reliability and performance.” SKF is a leading global supplier of bearings, seals, mechatronics, lubrication systems, and services which include technical support, maintenance and reliability services, engineering consulting and training. SKF is represented in more than 130 countries and has around 17,000 distributor locations worldwide. Annual sales in 2015 were SEK 75 997 million and the number of employees was 46 635. www.skf.com

Mines to gain control of yellow metal assets – aims to reduce fraud

SAMAR announces plans to cover entire life-cycle of all assets MIDRAND, SOUTH AFRICA – 25 May 2017 – The Southern African Movable Asset Register (SAMAR) today announces its plans that will allow mines, contractors, manufacturers, importers, builders, banks, insurers as well as the general public to control title and ownership of all movable assets, including yellow metal and other movable assets used during operations. In Africa, many yellow metal assets are crudely marked and registered to businesses. However, SAMAR creates the most recent reliable record of an asset and yellow metal by updating records in real-time as changes are made by various system participants. This allows businesses to effectively manage and control the financing of assets and yellow metal not on eNaTIS throughout their lifecycle. This greatly reduces fraud, theft, double discounting, or incorrect depiction for value and insurance purposes. Benefits for contractors • The value of movable assets and yello...

Reconditioning of components with Thermal Spray Coatings

Image
The application of Thermal Spray coatings by South Africa’s leading surface coating specialists, Thermaspray, can lead to an enhancement in performance and an extension of service life of expensive engineering parts and industrial components, leading to substantial reductions in downtime and production costs. Engineering components and parts in production processes are subject to degradation through wear, corrosion, oxidation and cavitation. Thermaspray, Managing Director, Dr. Jan Lourens, points out that as all these degradation processes are active on the surface of components, a suitably selected and correctly applied surface coating like Thermal Spray can effectively re-condition production equipment to ‘as new’. “In fact”, adds Dr. Lourens, “very often, through degradation analyses and the selection of a superior coating, a thermal spray coating makes it possible to provide virtually as good as new a component. Most importantly for the end user, this means substantial cost sav...

MEDIA STATEMENT A strong Health and Safety culture improves productivity and assists in creating a safe and great place to work. The health and safety dialogue company ensures labour force, management, community and all stakeholders are aligned in creating and respecting a safe and healthy working environment. Through workshops and visual campaigns, we bring your Health and Safety Policy to life. Legislation is designed to protect human life and to enforce safety standards. However, OHS Acts are often complex and difficult to understand especially in areas with low literacy. It is essential as a business to ensure your labour force truly understand the associated risks within their working environment; culture goes beyond ticking training boxes. Has your organisation considered the importance of promoting a Health and Safety culture? Are you confident your employees are living and working in a safety conscious culture beyond paperwork and legislation? The vision of the health and...
