They are removable and replaceable, to optimise no-maintenance performance in access infrastructure and high output plant such as mineral processing and oil, gas and energy infrastructure and conveyors in applications extending from ports to power plants. Performance characteristics include: • Outstanding stick-slip performance, to provide smooth, easy movement under load • Friction co-efficient 0.05 – 0.08 depending on stress • Expansion capacity up to ± 40mm for THE NEW UNIVERSAL COPPER PRESS-FIT CONNECTION SYSTEM FROM MM KEMBLA. www.kembla.co.nz KemPress A4 Ad.indd 1 5/03/14 10:01 AM EN073 demand sophisticated and typically more expensive solutions, but HLD bearings are very suitable for a wide range of bridge, materials handling and process equipment structures up to 60 tons per bearing.” Herculon type D sliding bearings – incorporating polymers proven globally for outstanding durability without lubrication or maintenance – were developed to fulfil the need for low-friction bearings on corbels and columns where continuous slip joints were not appropriate. (SUBHEAD)No-maintenance performance Type D Herculon Bearings (HLD/SG) are designed to accept a lateral load of 30 per cent of the vertical rated load, which can be dry-tech®: The lubricant-free, low-cost way to swivel, rotate, oscillate, move and achieve linear motion ... construct sustainably with dry-running polymer bearing solutions from igus®. the-chain: Moving energy made easy for any motion.

Hercules Engineering has provided cost-efficient slip joints and bearings to help protect and extend the longevity of landmark buildings and major industrial structures in Australasia, the Asia-Pacific and Africa The company has provided long-lasting product for use in structures as diverse as the Sydney Opera House, the Hang Seng bank in Hong Kong, Australia’s New Parliament House in Canberra and the world’s largest copper mine, Kansanshi, in Zambia. The company has also just released a new technical brochure which includes recommended slip joint solutions for optimum cost-efficiency and durability for buildings ranging from hospitals and shopping centres, carparks, transport terminals, office towers and warehouses through to factories, storage tanks, silos, boilers, smaller bridges (to 60 tons) and industrial and resources plants. Included is advice for technologies required for different types of structures located across areas of widely differing climatic and geographic diversity, ranging from the arid Australian Outback to Africa, Melbourne to Brunei, tropical and maritime. Herculon Type D Bearings (HLD/SG) consist of a mild steel top plate to which a polished stainless steel facing plate is welded. This plate slides against a low friction hard-wearing (PTFE) Hercuflon-coated Hercupad, which is in turn bonded to a mild steel base plate.
