Deep groove ball bearings made of plastic in a pool cleaner

Profile

What was needed?
Corrosion-resistant and maintenance-free bearing due to underwater application

Requirements:
lubrication-free, durable and corrosion-free

Industry sector:
Swimming pool and pool construction

Success for the customer:
Long service life, no relubrication of components necessary despite underwater use

Unclean floors and dirt in general in the form of leaves accumulate in swimming pools over the winter months and are difficult to remove. The Poolwonder Turbo XL pool vacuum cleaner provides a remedy. With its own weight of 1.4 kg and 40 cm suction width, it easily removes sand, leaves, moss and more from pools. The pool vacuum cleaner is battery-operated and is suitable for daily cleaning of pools up to 50 square metres in size.

Problem

Underwater use means that the use of metal ball bearings is out of the question. The lubricant is washed out or decomposed by external influences and the ball bearings run dry. Metal ball bearing solutions in particular are dependent on the use of external lubricants to ensure a long service life. The problem lay in the search for corrosion-free ball bearings for additional guidance of the motor shaft under the propeller and the first shaft seal.

Solution

xiros deep groove ball bearings made from the xirodur® B180 material are used for the additional guidance of the motor shaft under the propeller and the first shaft seal. The demand for lubrication-free and corrosion-resistant solutions led to igus®. Another plus point is the suitability of the bearing for the smallest and hard-to-reach installation spaces. In the Poolwonder, the bearing is enclosed between two seals, making relubrication virtually impossible.
