"Are there any warning signs of when a bearing is about to fail?" Think of a bearing failure as happening in four stages. During the first stage (or earliest detectable point using vibration analysis), the signals will appear in frequency bands around 250 to 350 kilohertz (KHz). In the ...

Main Advantages of Grp + Carborundum Stair Nosing 1. Light weight - an important factor in structural design considerations, has a great negative effect on load-bearing capacity such as bridges, multi-storey car parks, viaducts and so on, greatly pro... View More > Stainless Steel Stair...
The universal joints have bearing components that are greased at the factory. Now, this greasing can be used up or evaporated over time. Each rotation of the driveshaft makes the bearings twist a little. So, dry bearings cause metal-to-metal contact, and excessive friction leads to squeaking...
1. The PVC Tactile Indicator has the characteristics of light weight and light building materials, which can greatly reduce the floor load-bearing.2. Green environmental protection, non-toxic and harm... View More > Analysis of the Current Situation of the Irrational Pavement for Blind Unrea...
For meniscus surgery, a period of non-weight-bearing and restricted range-of-motion is usually implemented postoperatively to optimize the environment for healing of the tissues. A range-of-motion and strengthening program is subsequently implemented. In general, a goal of 6 months to return to ...
What we forget is that while self-less acts of kindness are truly admirable, they may not be healthy –physically or otherwise – if left unbalanced. If you were to be a bountiful tree, you need as much sunlight, water and other nutrients to continue bearing fruit. Neglecting essentials to...
