SKF Double Row Tapered Roller Bearings

SKF double row tapered roller bearings with two rows of tapered rollers, arranged back-to-back, can lock the unit axially. A large number of rolling elements, offering extreme precision between the raceways, gives massive load carrying capacity. In addition the double row taper roller bearing has a large diameter making it strong enough to withstand yaw and tilt moments. It is a taper roller bearing that can be pre-loaded. The only forces that reach the generator or the gearbox are torsional – those you use for generating energy and profitability.

SKF double row tapered roller bearings are produced in two configurations and in several different designs:
–The TDO configuration (fig); bearings of the TDO configuration have one double row outer ring (cup) and two inner rings with roller and cage assembly (cones).
–The TDI configuration (fig) which comprises one double row inner ring with two roller and cage assemblies and two outer rings.

In the world of SKF, the term “power density” has become increasingly common. Simply put, it’s about the relationship between weight and performance. The SKF double row taper roller bearing with a PEEK cage is an excellent illustration of what this term means in practice: you can radically reduce the weight of the nacelle, opening up exciting new opportunities. The really big turbines suddenly become possible – as well as the really light ones.

Friction is energy’s most formidable opponent. That’s why we fight it in every way possible. And with our double row taper roller bearing for wind turbines, we have come very far, which means you can take full advantage of even the lightest winds. And when wind speed increases you can still be calm. Low friction enables the lubricant to last longer, keeping maintenance to a minimum.Our primary weapon – clean steel, optimized designs and precision manufacturing – have been joined by a new cage. The segmented PEEK cage has helped us to reduce friction to a minimum, without risking operational reliability.

Tradition says that a turbine must always have a main shaft. And two bearings for handling radial and axial loads and tilting moments.At SKF, we have another solution.With a double row taper roller bearing designed specifically for wind turbines, you get a bearing that does the work of two. No need for an axle in between. Instead, the bearing is connected directly to the gearbox or generator and to the hub.And you know what this means. The weight of the nacelle is reduced radically. And all dimensions shrink.You get a bearing with a unique design that enables extremely low loss of energy. In fact, the friction in the SKF double row taper roller bearing solution is only a fraction of that found in a traditional design with two bearings and a main shaft.
