Deep groove ball bearings made of plastic in a pool cleaner

Profile

What was needed?
Corrosion-free and maintenance-free bearing for underwater use

Requirements:
Lubrication-free, durable and corrosion-free

Industry:
Swimming pool and pool construction

Success for the customer:
Long service life, no relubrication of the 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. A remedy is the pool cleaner Poolwonder Turbo XL, which with its own weight of 1.4kg and 40cm suction width easily removes sand, leaves, moss and more from the pool. The pool cleaner is battery operated and is suitable for the daily cleaning of swimming pools up to 50 square metres.

Problem

The use of underwater ball bearings made of metal is out of the question. The lubricant is washed out or degraded by external influences and the ball bearings run dry. Special ball bearings solutions made of metal rely on the use of external lubricants to ensure long service life. The problem was in finding corrosion-free ball bearings for additional guidance of the motor shaft under the propeller and the first shaft seal.

Solution

The xiros deep groove ball bearings made of 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 has led to igus. Another advantage is the suitability of the bearings for the smallest and hard-to-reach installation spaces. In the Poolwonder the bearing is enclosed between two seals, whereby a relubrication is hardly possible.
