XR-reeks gekruiste rolswaairinglaers bied 'n verskeidenheid oplossings, insluitend hoë styfheid en lae rotasiewringkrag binne 'n minimale omhulsel. XR-reeks draairinglaers is ideaal wanneer vierpuntkontakkogellaers nie aan die loopwerkverrigtingvereistes van wringkrag en styfheid kan voldoen nie.
The internal structure consists of cylindrical rollers with a V-groove in each circle. The rollers are oriented with alternating axes of rotation. Bearings positioned in this manner can accommodate all combinations of radial, thrust and moment loads. Rotational torque is less than a four-point contact ball design because each roller transfers load in only one direction, and the roller-ball contact area and geometry are larger, providing greater rigidity and rigidity.
A roller roughly the same size as a sphere has a greater load carrying capacity. However, since not all rollers face in one direction, they have less thrust and moment load capacity than four-point ball bearings.
Gear teeth or other drive mechanisms can be provided on the inner or outer support ring, and a hole pattern of your choice can be added for bearing retention.
XR Series Crossed Roller Slewing Rings are custom manufactured to design and specification.
XR series slewing ring bearing solutions have been successfully used in applications requiring additional stiffness and low torque requirements, including:
