In addition, the discharge through the radial bearing
ensures a safe, clean, and even feeding on the next conveyor reducing loss of materials.
For example, an oil-lubricated 45mm radial bearing
running at constant load and speed under ultra-clean conditions (nc = 1) has been calculated to complete 15,250 operating hours.
We confirmed that the shaft inaccuracy is the significant parameter influencing the coefficient a (in (1)) along with other important parameters such as tribology conditions, radial bearing
clearance, load, and so on.
This combination of ceramic ball bearing on the fore vacuum side and permanently magnetic radial bearing
on the high vacuum side provides a particularly robust bearing concept.
According to the definition of contact stiffness, the Hertz contact stiffness of ball radial bearing
can be obtained as:
Further, each individual axle is mounted to a radial bearing
that provides a tighter steering system for a more stable platform.
This configuration can be used as a radial bearing
as it develops positive radial force and stiffness (negative axial force and stiffness).
Because the armature is a large radial bearing
, performance in such critical areas as stiffness and runout are said to be superior to conventional, longer spindles.
The motor actually serves as the radial bearing
, allowing a shorter overall length of the assembly.
They also must be identical in diameter and radial bearing
surface to avoid bending pressures and stresses in the wheel structure.
