Journal Bearings and Their Lubrication

Journal or plain bearings consist of a shaft or journal which rotates freely in a supporting metal sleeve or shell. There are no rolling elements in these bearings. Their design and construction may be relatively simple, but the theory and operation of these bearings can be complex. This article ...

Bearing self study guide

bearings perform the same function and have the same objective – to keep the shaft moving smoothly and consistently while reducing friction. A bearing's rolling internal mechanism greatly reduces the effort and energy it takes to slide or move an object over the surface. This is why the

As the concrete hardens, the bubbles disintegrate or transform, releasing the water which is absorbed into the cement matrix, thus aiding in the hydration process and leaving air voids of similar sizes. Thus, there is less need to wet the concrete during curing, as is normally necessary with conventional, unfoamed concrete.

Concrete Slab Rebar Spacing Guideline | Hunker

There's no generally-accepted rule of thumb as to how to space rebar in a concrete slab. There are many variables that influence the decision of how much space to leave, including the maximum load the slab is likely to have to support, the bearing capacity of the soil, the diameter of the reinforcing rebar, the likelihood of frost heaving the slab, and whether or not the slab is on a level grade.
