The main cause of vibration in washing machines is an unbalanced load due to unevenly distributed clothes. During the spin cycle, the load is “pinned” on one side of the spin basket due to centrifugal force. This can make the machine “walk”, causing damage to…

read morePower tools have been known to induce the risk of vibration-related diseases. An acute disease that is caused by regular exposure to hand-arm vibration (HAV) is known as white finger or Raynaud’s disease. There are also other vibration-related diseases such as: permanent and painful numbness…
read moreBalancing has been an important function in industries that produce or utilize rotating machinery and equipment. The reason for balancing rotating equipment is because most materials and manufacturing processes are inherently flawed to some degree. It is extremely difficult to achieve a perfectly balanced product…
