AS81820A is for a bearing that has been tested to 100,000 cycles. AS81820C is still valid. It has not been superseded by 81820A. 81820A is another class of bearing. TPAC isn't 81820A certified, but so what? There is a lot of business from people who don't care if it is Type A or not. Remember that NAVAIR does testing and gives approval based off of the SAE-AS81820 standard. The SAE-As standard is what governs. It establishes the testing criteria and the approval granted to TPAC was under SAE-AS81820, so that standard applies. So even if you pull something off of the NAVAIR site, it may not apply, when the approval is to an SAE-AS standard. I hope that makes sense.
And of course they made parts. I got their parts. Pax River got their parts. If you read SAE-AS81820 the veil will be lifted. You will see that in order to qualify, the guys trying to qualify must submit PARTS to the Navy for testing. They must make the parts. TPAC has done this through their WFOE.
4.3.2 Sampling Instruction
When the qualifying activity is conducting the actual qualification tests, qualification test samples shall consist of 37 bearings of MS14101-8, or MS14101A-8 for Type A bearings, 11 each of the sizes in column Iof Table 3A or 38 and 6 each of the sizes in column II of Table 3A or 38 upon which qualification is desired. All bearings necessary for tests shall be furnished by the manufacturer and shall be representative of his normal production. Samples shall be permanently marked with the test bearing number and forwarded to the activity designated in the letter of authorization from the activity responsible for qualification (see 6.3).
So you see, they had to make parts and had to submit them for testing. It is all in the spec.
