SIMSITE® Bearings are not cast, poured, extruded, or molded, rather, they are a structural composite. They are precision machined from a solid bar of ourpatented Simsite® material. Because the fibers are not chopped up, or cut, Simsite® bearings have a much higher shear strength, bond strength, flexural strength, and tensile strength. SIMSITE® Bearings will not crack or break like carbon, or non-structural composite bearings. The high mechanical properties enable the bearings to withstand higher loads and torque requirements.
Unlike rubber, extruded, non-structural composites, or thermoplastic bearings; SIMSITE® Bearings are made from structural graphite fibers which are continuously interwoven in a tri-dimensional weave, and therefore are much stronger and much more durable than rubber, elastomer, non-structural composite, or plastic. They are also not subject to cracking.
Because SIMSITE® Bearings hold the shaft more securely than conventional bearings, radial movement in the shaft is reduced. This increases the life span of the entire rotating element.
When you combine a SIMSITE® Impeller and casing rings with a Simsite® Guide Bearing the length-to-diameter (L/D) of the rotating element is reduced. The stability of the rotating element is therefore improved because of the lower mass. This lower mass (approximately 1/6 the weight of bronze) accounts for its excellent PV characteristics
