a first flange ( 3200 ) having a first flange first end ( 3210 ), a first flange second end ( 3220 ) opposite the first flange first end, and a cylindrical profile having a first flange exterior surface ( 3230 ) and a first flange interior surface ( 3240 ) defining a first flange inside diameter ( 3250 ) and a first flange outside diameter ( 3260 );

a second flange ( 3300 ) having a second flange first end ( 3310 ), a second flange second end ( 3320 ) opposite the second flange first end, and a cylindrical profile having a second flange exterior surface ( 3330 ) and a second flange interior surface ( 3340 ) defining a second flange inside diameter ( 3350 ) and a second flange outside diameter ( 3360 );

a bearing cap ( 3400 ) having a bearing cap first end ( 3410 ), a bearing cap second end ( 3420 ) opposite the bearing cap first end, a cylindrical profile having a bearing cap exterior surface ( 3430 ) and a bearing cap interior surface ( 3440 ) defining a bearing cap inside diameter ( 3450 ) and a bearing cap outside diameter ( 3460 ), and a third flange ( 3480 ) extending from the bearing cap exterior surface proximate to the bearing cap second end;

a bushing ( 3500 ) having a bushing first end ( 3510 ), a bushing second end ( 3520 ) opposite the bushing first end, a bushing inside diameter ( 3530 ), and a bushing outside diameter ( 3540 );

a stop washer ( 3600 ) having a stop washer first end ( 3610 ), a stop washer second end ( 3620 ) opposite the stop washer first end, a stop washer inside diameter ( 3630 ), and a stop washer outside diameter ( 3640 ); and

a snap-ring ( 3700 )

wherein the central stud second end is attached to the first flange first end; the first flange second end is attached to the second flange first end; the bearing cap, the bushing, and the stop washer fit around the central stud exterior surface; the bearing cap is located between the first flange first end and the bushing second end; the bushing is located between the bearing cap first end and the stop washer second end; the snap ring is mated to the snap-ring groove below the stop washer first end; and the first flange outside diameter is greater than the second flange outside diameter.

2 . The bearing assembly of claim 1 , wherein at least a portion of the first flange interior surface is countersunk.

3 . The bearing assembly of claim 1 , wherein at least a portion of the second flange interior surface is countersunk.

4 . The bearing assembly of claim 1 , wherein the central stud comprises a hole ( 3190 ) passing from the central stud exterior surface to the central stud interior surface proximate to the central stud second end.

5 . The bearing assembly of claim 1 , wherein the third flange comprises a plurality of slots ( 3485 ) located along a circumference of the third flange.

6 . The bearing assembly of claim 1 , wherein the bearing cap comprises a plurality of screw holes ( 3490 ) passing from the bearing cap exterior surface to the bearing cap interior surface.

7 . The bearing assembly of claim 1 , wherein the first flange further comprises a first lip ( 3270 ) extending from the first flange second end.

8 . The bearing assembly of claim 1 , wherein the second flange further comprises a second lip ( 3370 ) extending from the second flange second end.

9 . The bearing assembly of claim 1 , wherein the bearing cap further comprises a third lip ( 3470 ) extending from the bearing cap first end having a third lip inside diameter.

10 . The bearing assembly of claim 1 , wherein the bearing assembly is part of a cryogenic freezer.

11 . A bearing assembly ( 3000 ) for a turn-table of a cryogenic freezer comprising:

a bearing ( 3550 ) having a bearing inside diameter ( 3551 ), and a bearing outside diameter ( 3552 );
