Simplex Bearings
Intermediate Shaft Bearings
The operational efficiency of a machine or plant is determined by, above all, the bearing quality at all rotating components. This applies in particular to the line-shafting of ship propulsion plants. The Simplex bearings were developed especially for this purpose as short, plain bearings. More than 21,000 have left our works to date.
Simplex bearings are characterized by a short shell length. Moreover, they can be precisely aligned to avoid edge loading. The running properties of the bearing metal have been optimized with a technically highly advanced bonding of bearing metal and shell. The vital lubrication of the bearing is safeguarded in the Simplex bearing at all times, even at low shaft speeds. Temperature sensing and monitoring systems are also supplied. Cooling systems are available for unfavourable operating conditions.
High-Load Thrust Bearings
Our Simplex HL thrust bearings are single-collar bearings for taking up the thrust loads produced by the ship's propeller. Other applications, such as with turbines, air blowers, cutter suction dredgers and centrifugal pumps, are also possible. If required, the bearing's internal parts can also be fitted into gearboxes or, by using flange-type casings, onto engines and motors. Of course, our Simplex HL thrust bearings are manufactured in accordance with the rules of all international classification societies.
The thrust shaft with the solid forged collar transmits the thrust to the bearing casing. In an axial direction, the thrust collar is guided on both sides by the tilting pads. These pads rest on a spherical base and are directly supported on the casing. They can be inserted and removed through an assembly opening without the need to take off the bearing's upper casing half.
The shape of the HL tilting pads offers you improved oil flow, more effective cooling, lower friction and hence a reduced loss of efficiency with an increased service life. At the same time, the Simplex HL thrust bearing gives you maximum strength and stability. This is due to the robust, ribbed design of the casing with the stiffened supports of the tilting pads as well as its centreline mounting on the foundation. In addition, these technical features reduce the tilting moment.
Depending on your requirements, we configure the Simplex HL thrust bearings in combination with a radial bearing or, above size 500, as pure thrust bearings.
