Bearing Off A player bears off a checker by rolling a number that corresponds to the point on which the checker resides, and then removing that checker from the board. Thus, rolling a 6 permits the player to remove a checker from the six point.
Do you get to roll again after doubles in Backgammon?
If the players roll the same number, they must roll again. If a player rolls two of the same number, called doubles, that player must play each die twice. For example, a roll of 5-5 allows the player to make four moves of five spaces each.
Which is the safest way to remove a bearing?
These devices, used correctly, can safely remove a press-fitted bearing from a shaft. But in many cases, the jaws of the puller don’t reach the inner ring, which would be the safest place to apply the pulling force. So, we place the puller jaws on the outer ring and tighten the center spindle of the puller to apply the removal force.
What are the causes and cures of bearing failure?
‘Ihe temperature rise can also degrade or destroy lubricant Common culprits are heavy electrical heat loads, inadequate heat ~aths. and insufficient coolinx or lubrication when loads and speeds are excessive. Thermal or overload controls, adequate heat paths, and supplemental cooling are effective cures. Look for bluelblack and silv~rlgold
What happens when a bearing falls off a shaft?
Idea is to get the heat into the inner race. When the inner race expands, it turns loose and creates an air gap. Once the gap is formed, even less heat is transferred to the shaft, speeding expansion of the race. When you hit the magic temp, the bearing falls off. No marring of the race, no problems.
What kind of paper do you use to clean a bearing?
Although emery paper is commonly used in industry for this purpose, keep in mind particles loosened from the backing paper may contaminate the bearing. Preferably, industrial Scotch-Brite pads should be used to clean the shaft or housing of any fretting or corrosion.
