There is no corelation between a cylinders ID to OD.
if you mean a cylinder with a hole through it like a pipe or tube, then it's pi x (Od2 - id2)/4 x h Od = outer diameter id = inner diameter
wall thickness of pipe is (OD - ID) /2
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs
If you Google "mild steel density" you find that a value of 7.85 is not uncommon.If you calculate the volume of steel in your pipe (Google "volume of cylinder") calculate the volume of the OD cylinder and subtract the volume of the ID cylinder and multiply that by the density you get the mass of the pipe multiply that by the gravitational constant (Google "gravitational constant") of your location to get the weight.Or you could just Google "ms pipe weight calculator" (see the Sources and related links below) find the pipe shape and put in your values, hit "Calculate" and get the answer 34.6889 lbs (which has far too many significant figures (converted to kg by Google as 15.7 kg still with one significant figure too many as two of the original dimensions only had two significant figures)
To calculate the outside diameter of a steel coil, you first need to determine the inside diameter (ID) and the thickness of the steel material. The outside diameter (OD) can then be calculated using the formula: OD = ID + 2 × thickness. If the coil is wound in layers, you may also need to account for the number of layers by adding the thickness multiplied by the number of layers to the ID.
if you mean a cylinder with a hole through it like a pipe or tube, then it's pi x (Od2 - id2)/4 x h Od = outer diameter id = inner diameter
wall thickness of pipe is (OD - ID) /2
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
The ID of a pipe (inner diameter) can be calculated by subtracting the pipe's wall thickness from its outside diameter. The formula is ID = OD - 2*WT, where ID is the inner diameter, OD is the outer diameter, and WT is the wall thickness of the pipe.
assuming it's hollow. 10.68*ID*(OD-ID)
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs

The bearing number can be checked out depends on the size of ID (Inner Diameter), OD (Outer Diameter) and H (Height) of this bearing.
it means outside diameter as opposed to id which is internal diameter
The prefix od- otherwise known as ob- means toward, against, or completely.
