Influence of Foundation Rigidity on the Structural
Oct 08, 2021· When the relative soil-to-mat rigidity is high (e.g., thin mat on rock), a vertical load applied on the mat causes large bearing pressure over a narrow width loed just below the load. For a foundation with moderate relative soil-to-mat rigidity ratio (e.g., medium thick mat on dense sand or stiff clay), the soil bearing pressure is reduced
Super Precision Bearings - Emerson Bearing
Ball and roller bearings are employed in all types of mechanical systems, but choosing the correct type can be daunting. Ultimately, the ideal bearing for a specific appliion will be determined by the speed of operation, the direction and magnitude of the load, and accuracy and rigidity requirements. When high speed and accuracy are necessary, super precision …
NSK develops ‘world’s fastest ball bearing for EV motors
Jun 17, 2021· An ultra-high speed ball bearing for electric vehicle motors has been developed that claims to be the world’s fastest grease-lubried deep groove ball bearing for EV appliions. Capable of operating at over 1.8 million dmN, the technology is said to enable longer vehicle range and higher energy economy for electric vehicles.

NYT1 Type. The STUDROLLER system is based on a new concept to provide prevention of roller cage slippage. This system enables "anti-cage-creep" during operation, making them ideal for use in vertical or high-speed appliion. We added a size "1" with 1.5mm roller diameters to this series. Anti-corrosion types are also available.
Proposal of a High Rigidity and High Speed Rotating
May 15, 2009· In this paper, a high rigidity and high speed rotating mechanism using a new concept hydrodynamic bearing in X-ray tube for high speed computed tomography is proposed. In order to obtain both the stability and the high load carrying capacity, the hydrodynamic bearing lubried by liquid metal (Gallium alloy), named as the hybrid hydrodynamic

Bearing Capacity - an overview | ScienceDirect Topics
Stewart W. Johnson, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.D Bearing Capacity. Bearing capacity of the lunar surface relates to the capability of the lunar soil to support a structure, a vehicle, or another object. The ultimate bearing capacity is the maximum possible load that can be supported without failure (e.g., by overturning of a building).
