Video of the Week – multi-dimensional drylin® E gantries

Combining numerous linear axes to allow multi-axes movement, the drylin® E range of gantries from igus® provides flexible multi-dimensional solutions for a variety of applications, such as automation, measurement and positioning systems. Thanks to the self-lubricating nature of the drylin® components, the gantries are maintenance- and corrosion-free, which makes them a clean and low-cost solution especially in the medical, food and packaging industries.

Part of the complete range of dry-run linear drive systems, drylin® E gantries are available from stock and dispatched within 24 hours in all three basic options: line gantry with a working space of 500x100mm, flat gantry operating within 300x300mm envelope and a room gantry reaching each point within 500x500x100mm.

RoHS Update: igus highlights environmental benefits of their iglidur bearings

igus is helping machinery and equipment manufacturers, who are required to adhere to the RoHS Directive, achieve more reliable performance with lowered environmental impact by switching to iglidur plastic bearings. iglidur plastic bearings are well-suited to a wide range of applications including those found in the automotive, transportation, construction, industrial, medical and food & packaging industries.

“Up until 1 July 2008, bearing manufacturers were given an exceptional provision, which allowed them to continue putting lead-containing and therefore potentially hazardous bearings on the market,” explains Rob Dumayne, director, igus. “This exemption has long passed and, although most bearing manufacturers have invested heavily to ensure their products comply with the requirements specified in the RoHS Directive, some are still missing the target.”

Typical application examples include the use of lead in solder, or as an ingredient in metallic composite bearings, and the use of PBB as a flame retardant, these restricted substances also commonly occur in metallic alloys.

“Steel-backed bearings with a lining of PTFE based material are still available on the market,” adds Rob. “In some cases, this material can contain lead additives and for this reason the bearing would do not comply with the RoHS Directive. REACH compliance is also an important factor to consider as often bearings that contain a sintered material can be impregnated non-regulatory oils.”

Additionally in the Medical Technology industry from 22nd July, any products such as plain bearings face extinction if they have high concentrations of lead within them, this is further evidence for the use of igus dry-tech polymer bearing systems, ensuring legal, safe and future proofing functionality to the manufacturer.

All igus bearings are RoHS2 and REACH compliant. For more information or to receive the igus Certificate of Conformance to RoHS2, please contact igus directly on 01604 677240 or visit the website at: www.igus.co.uk/RoHS

Polymer bearings expert igus has developed knife-edge conveyor rollers for materials handling applications. Manufactured using igus’ iglidur materials, the knife-edge rollers are cost effective, quick and easy to install and provide a long service life to the conveyor system.

Providing a tight deflection radius, the rollers are moulded from lubricant and chemical free materials to ensure no contamination of food/product, thus providing a reliable solution for packaging and food industry applications. In addition, selected iglidur materials are FDA approved.

Three iglidur materials are available to cover a range of operating temperature requirements up to 180° Celsius and require a low torque to provide a cost-effective running solution and replacement for existing rollers.

Brand new launch: xiros® End Cap Ball Bearings, a real plastic for longer life

High-performance material, Xirodur B180, ensures a reliable wear resistant and durable bearing ideal for a variety of application areas. The self lubricating and water-proof nature makes this a perfect solution for the food and packaging industry.

Xiros product manager, Dean Aylott from igus, gives us his top 5 application problems that a Xiros ball bearing solves within the food industry:

  1. Food Contamination:

The self-lubricating and FDA approved material properties eliminate the need to add lubrication therefore reducing food contamination.

  1. Heavy machinery:

The light-weight nature reduces weight in the food packaging machines.

  1. High level of friction/ static build-up:

Xiros bearings reduce friction enabling you to run your machines at higher speeds with less drag, increasing productivity.

  1. High demand in maintenance:

Maintenance-free nature; increasing service-life and reducing costs.

  1. Long or time-consuming installation process:

Maintenance-free, no need for un-scheduled downtime. Replace greased steel and stainless steel ball bearings.

xiros® success stories

By swapping to plastic, we have had success in a number of applications. igus recently had an application where steel ball bearings were insufficiently maintained on a UK built machine, that was wrapping confectionary goods overseas. Steel ball bearings were sprayed down with a chemical product/ solution which in-turn penetrated the seal and corroded the original bearing.

The company made an enquiry to igus for a solution to their problem. igus products proved to be of favour and from what was a three week failure rate , igus have completely turned around. Now as it stands, the bearings are still operating within the application two years later. Outstanding feedback! Not only have igus products extended the machine service life, they have also enabled the customer to increase through-put and dramatically slash costs.

The new addition to the xiros® family

The Xiros product range has been extended: the new Xiros End Cap Ball Bearings for larger diameter rollers, such as those used within the success story example above. They feature not only sacrificial ribs for easy installation, yet can withstand a vast range of temperatures from -40°C to +80°C and have a load rating of 294N per bearing.

“The Xiros End Cap Ball Bearings are exactly what the food packaging industry needs.” Dean Aylott enthused, “They can withstand the dynamic and challenging environments that are faced by this industry, making it a reliable and durable market component. With products like these, we can bring the traditional method of conveying inline with 21st Century technology”.
