A new black coloured guide roller with smooth-running polymer ball bearings has been designed and manufactured - following a customer request and extensive testing by the team at igus. The product, which uses black anodised aluminium tubes, is the latest in the xiros film guide roller range, largely used in the fields of packaging and food technology. igus, whose UK headquarters are in Northampton, are motion plastic experts and a global manufacturer of energy chain systems and polymer plain bearings.
Matthew Aldridge, Managing Director, igus UK, said: “As with any of our igus products, the idea for this new design was put forward, prototypes were designed and after extensive testing, the results were positive and showed nothing detrimental in comparison to the original clear anodised aluminium roller. A new product was born.
"The idea for the black design arose from a customer enquiry. The technical specifications of our classic aluminium rollers were already very convincing, but black visible parts were desired for this labelling machine.
"This soon resulted in a product that met the customer's requirements - not just in terms of technology but also in price and appearance. The new black roller, since it does not reflect light, has the added benefit of working smoothly with vision systems.”
Fully assembled, the xiros standard roller systems include a tube made of aluminium, carbon, or PVC, which is then fitted with xiros bearings. These xiros polymer ball bearings are lubrication-free, maintenancefree, hygienic and have a low breakaway torque. The complete system acts as a guide roller for deflecting films and labels or for conveying goods.
By using wear-resistant high performance polymers and thin-walled tubes, they provide a weight saving of up to 48% compared to metallic solutions.
Their mass inertia is 42% lower, and therefore the energy required for acceleration is considerably lower. This means the rollers can reach the conveyor speed faster.
Find out what specification you need: Go online and specify the outer and inner diameter you require, as well as the length of the roller, the load, speed, and the ambient temperature. You will also need to enter the acting force and the degree of wrap around.
The online igus calculator will then suggest the appropriate tube materials. In the second step, stay online and select the guide roller based on the deflection, weight, and price data, download the configuration CAD data, and order the xiros rollers directly online.
