Alka - Model Premium Series -Thrust Bearing for Submersible Pumps

SILICON CARBIDE materials further extend the load and temperature capabilities of bearings, retaining high strength at temperatures of 1100°C (2012°F).

Given their superior strength and hardness, as well as their thermal conductivity, SILICON CARBIDE materials are frequently used in process lubrication where films are very thin and/ or contamination of the lubricant is possible. Like polymers, SILICON CARBIDE can operate on thin films, but while sand or ferro debris enters the lubricant, SILICON CARBIDE materials grind it down.

Challenge come for when the thrust bearing has to work with high thrust loads (when pump to installed deep beyond capacity of conventional bearings). To overcome this, the material science and geometry design put together worked and came out with these Ceramic bearings.

For these THRUST bearings to operate reliably under any conditions, however, the mating surface must be made of SAME MATERIAL The reliable operation of these pairings is typically validated first by in-house testing, then by field trials.
