Load Capacity - an overview | ScienceDirect Topics

Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifiions. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration). Dynamic forces must include any external forces, such as vibrations, acting upon the stage.

What is a spindle bearing?

Spindle ball bearings are single-row angular contact ball bearings with a contact angle of 15 or 25 that can support load on one side. In respect of their design, their running accuracy and the materials used, they are optimised for highest speed and great bearing capacity.

Radial Load - an overview | ScienceDirect Topics

Figure 12.11 shows maximum radial and axial loads that may be applied in coination for a four-recess hydrostatic conical bearing. Short L/D bearings allow higher radial loads per unit area than longer L/D bearings. With L/D = 1, larger thrust loads are possible but radial load capacity reduces as axial thrust loads are increased.

Implementing a high-load ball screw, on the other hand, would double the load capacity and yield eight times the life, getting more value out of the drive while reducing maintenance costs. It also enables the manager of each production unit to optimize for higher load capacity, longer assely life or an acceptable balance of both.

Stability of Water-Lubried, Hydrostatic, Conical Bearings With Spiral Grooves for High-Speed Spindles …

1/2/2001· In this paper, the stability of water-lubried, hydrostatic, conical bearings with spiral grooves for high-speed spindles is investigated theoretically and experimentally. In these bearing types, pressurized water is first fed to the inside of the rotating shaft and then introduced into spiral grooves through feeding holes loed at one end of each spiral groove.
