Terminology and Tolerances

1. Delefcted Height (H1)
This is the height at which the washer should be compressed to measure the load.

2. Insdie Diameter (ID)
Washers were designed to fit over a rod as published in the catalog. Therefore, the I.D. values are greater than the listed minimums. This allows for sufficient clearance when the washer is deflected.

3. Load at H1 (Load)
The catalog lists the nominal load which can be expected when the washer is deflected to the height "H1". The loads are based on a process capability index of 1.33Cpk.

4. Outside Diameter (OD)
Washers were designed to fit into hole as published in the catalog. Therefore, the O.D. values are less than the listed maximums. This allows for sufficient clearance when the washer is deflected.

5. Overall Height (H)
The overall height "H" is an approximate value. It is slightly adjusted around the published value at manufacturing to meet the load at the deflected Height "H1". It should be noted that the height is the only variable that is adjustable in the manufacturing process due to the O.D., I.D. and material thickness being fixed.
