Note 1: Groove Depth = machined channel
Gland Depth = Groove Depth + Clearance

Note 2: The following sizes are not normally recommended for dynamic service, although special applications may permit their use:

Note 3: Clearance shown are based on 70 durometer materials. The clearances must be held to an absolute minimum consistent with design requirements for temperature variations and should not exceed the values shown.

Note 4. Total indicator reading between groove and adjacent bearing surface. All surfaces and corners musts be free of tool marks and scratches.
