GENERAL NOTES:
(a) All dimensions are in millimeters.
(b) Tolerances:
A = width of ring, +0.20, −0.00
Variation in width throughout the entire circumference of any ring shall not exceed
0.10 within these tolerances.
C = width of flat, +0.15, −0.00
D = height of outside bevel, +0.0, −0.76
E = hole size, ±0.5
H = height of ring, +0.20, −0.00
Variation in height throughout the entire circumference of any ring shall not exceed 0.10 within these tolerances.
OD = outside diameter of ring, +0.51, −0.00
R1 = radius of ring, ±0.5
23 deg = angle, ±0 deg 30 min.
NOTES:
(1) Rings RX-82 through RX-91 only require one pressure passage hole as illustrated. The centerline of the hole shall be located at the mid-point of dimension C.
(2) Tolerance on these dimensions is +0.5, −0.0.
