Oil-whirl instability in rotor bearings was discovered by General Electric engineer Burt Newkirk in the 1920s. Since then, much has been written about design methods to reduce its harmful effects. Yet ...

Railteco’s WY2 Rolling Bearing Press-Fitting Machine is designed for non-axle box rolling bearing press fitting for railway freight vehicle wheelsets. It is controlled by a computer that can ...

The Large Bearing Testing Machine has been developed and primarily used for commercial testing of large bearings. It is capable of applying 1,600 kips (7,117 kN) vertical load, and lateral ...

• Sleeve bearings in moderate service can operate on 50% or less of the oil feed required for a full hydrodynamic oil film. • Lower oil-feed rates mean engineers can simplify oil-delivery systems. • ...

YCY Mobile Rolling Bearing Mount and Demount Machine is flexible in movement, free from site constraints, providing bearing press-fitting and withdrawing at the wheelset repair site. Press-mounting ...

The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...
