The bearings are an essential component in aeration windmills. These windmills aerate ponds in private and public spaces because fan rotation is key to ensuring that a diaphragm moves up; compressed air is taken in; and the compressor builds up pressure, which is released into the air line leading to the water.
Because of this, the windmills are more efficient at reducing algae and foul smells, controlling mosquitos and creating a healthier environment for fish.
Vesconite Bearings’ Eddie Swanepoel notes that the 60-in. fans rotate at 15mph and weigh 35lbs, with aeration windmills ranging in size from 20 to 30-ft.
These large windmills are difficult to lubricate, so having a bearing made of a self-lubricating polymer ensures the continued movement of the fan, he says.
The full benefit of wind energy is also available as a result of the frictionless bearings, which ensure that windmill fans can rotate smoothly, Swanepoel indicates, noting that aeration windmills also reduce the monthly costs associated with electric aerators.
The windmill manufacturer orders about 100 bearings a year, and advertises the advantages of its superior bearings in its aeration windmills and its decorative windmills, for those interested in enhancing their gardens with this feature.
As a result of the interest in its bearings for this application, Vesconite Bearings stocks the required bearings as standard stock items.
