Questions about this item

Which SKF 7414 shaft seal size fits my 0.75 in shaft?

The SKF 7414 is sized for a 0.75 in inside diameter, 1.124 in outside diameter and 0.188 in overall width.

What does the 3,960 RPM rating mean when the seal is installed?

It is the maximum rotational speed the nitrile lip can sustain without excessive heat buildup; actual limit depends on lubrication and shaft finish.

How does the CRW1 design code limit pressure in service?

CRW1 denotes a single-lip, spring-loaded nitrile seal rated to 10 psi maximum pressure; exceeding this can cause lip roll-over and leakage.
