The Rink company relies on plain bearings from igus® in its beverage machines. In the valve heads, which are used for emptying bottles, chemical-resistant iglidur ® J-guide rings replace the previously conventional piston rod seals, which often did not provide the desired stability.

A patented filling valve is used in the KHS filling system for CO2-containing beverages, in which PET bottles are pressed by the product pressure. The design engineers were looking for a bearing that could withstand temperatures of up to 140°C and was resistant to all cleaning agents used in the beverage industry. The solution: a plain bearing in a special shape made of iglidur   ® X material.

At Big Drum Engineering, O-rings were initially used to support and guide the piston in the valve, which is used to fill ice cream with pieces of fruit, but these quickly wore out. The design engineers finally replaced them with a new special seal and iglidur ® J bearings, which serve as support and guide rings for the piston. This minimised the wear and there are no more piston jams.

In its disc valves, the company Nocado relies on iglidur ® G plain bearings in a special shape. Equipped with a slot and a spring, the bearings engage quickly and without tools on the shaft ends of the disc, which are provided with a groove. This means that a third hand is no longer required to prevent the bearing from falling out during assembly or maintenance of the disc valves.

Our chemical and temperature-resistant iglidur ® X bearings are used in the ecoflow diaphragm metering pumps from LEWA. Installed in the drive unit, they minimise wear on the piston rod pin.

Specially manufactured clip bearings on iglidur ® J material are used in the infusion pumps of B. Braun Melsungen AG. They are easy to install in the tight installation space and manage without external lubrication, which is absolutely necessary in this application to avoid contamination. Thanks to their low friction coefficient, the infusion pump can operate smoothly despite very short strokes.

Iwaki had originally used metal spherical plain bearings in its dialysis pumps, which required constant relubrication. They then tested dry-running igubal  ® spherical plain bearings in a pump that was moved for over 10,000 hours in a temperature cycle of -10 to +60 degrees - with success. Since switching to igubal®, the pumps have been running reliably and trouble-free for many years.

In order to realise swivel and linear movements in the complex gear unit of their solar water pump, the designers at BSR Solar Technologies were looking for robust, low-cost plain bearings and found what they were looking for at igus®: Several flange and clip plain bearings made of various iglidur® materials ensure reliable movement without maintenance effort.

The company Wye uses hydraulic cylinders in scissor lifts that provide the lifting mechanism for tipper vehicles. Because the metal bearings regularly rusted and wore out, they quickly switched to our lubrication-free igutex ® TX1 high-load bearings, which are extremely wear-resistant and dimensionally stable thanks to their long-fibre winding design.

In its special hydraulic cylinders, the Chapel Group relies on iglidur ® G plain bearings. In addition to short delivery times, they also score with technical advantages: Compared to the previously used brass bushings, they are significantly more economical and, with diameters of 20 to 45 mm, prove to be extremely wear-resistant and weatherproof.
