Precision seed sowing machine: Low-maintenance, durable

• What was needed: iglidur Z thrust washers
• Requirements: a cost-effective bearing that could permanently withstand high pressure and was free from maintenance and lubrication.
• Industry: agriculture
• Success for the customer: the iglidur thrust washers offer the manufacturer a solution that is as simple as it is powerful. They are lubrication-free and particularly wear-resistant. This enables them to withstand the heavy load permanently and safely.

This particularly wide precision planter is used in the agricultural industry in large markets such as the USA, South America and Eastern Europe. 
The Italian agricultural machinery manufacturer Maschia Gaspardo sometimes builds such implements and was looking for a suitable mounting solution for the suspension of the large wheels on the sides of the trailer. The wheels can be swivelled freely and enable easy manoeuvring at the end of the field. There is high pressure on the wheel bearings as they have to bear the weight of the machine. Various bearing systems were proposed and considered: however, a thrust bearing is too expensive, is difficult to protect from the high levels of dust and requires time-consuming adjustment of the housing. A steel washer with lubricant was also out of the question as an alternative. Although this is a cost-effective solution, the washers would have to be replaced annually and relubricated daily.

A simple and at the same time ideal solution to the problem was found in an iglidur thrust washer, which offers the perfect conditions for use in this area thanks to its material specifications. The thrust washers made of the material iglidur Z (more specifically, the ZTM-6590-020 thrust washers) were primarily selected due to their wear resistance. As they are lubrication-free, they make the seed drill considerably easier to use and reduce running costs. We offer thrust washers with a wide range of dimensions from stock in our product range. Other shapes and dimensions according to your specifications can be manufactured from iglidur bar stock using both injection moulding and by being machined.
