Finite element method (FEM) analysis was undertaken to produce compact cylindrical roller bearings that save weight, and  Cylindrical roller bearings absorb uneven load distribution, delivering optimised life in a patented new multi-stage planetary/helical unit that extends the development of wind energy plants into the multi-megawatt area, ie up to 5MW and above.

In the differential gearboxes, unlike conventional generator gearboxes of the multi-megawatt class, four or more planetary gears do not revolve around the sun wheel in the input stage. Instead, they have two input stages Cylindrical roller bearings wholesale, A1 and A2, each fitted with three planetary gears, offering the advantages of a static determination paired with freely adjustable sun pinions.

cylindrical roller bearings meet modern industry demands for improved levels of load capacity, reliability and operating life. They provide higher performance, substitute for two-piece brass cage designs - and also competitive one-piece designs - in applications where increased performance demands mean that the latter bearings can offer either the life, or the levels of reliability required.

The key to the increased complement of larger rollers of the EM Series bearings - and their commensurate higher load capacity - is the improved strength of the unique one-piece brass cage design. In tests the cage of the Cylindrical roller bearings manufacture has proved to be four to five times stronger than the two-piece designs of major competitors and two times stronger than competitive one-piece designs.
