Features & Benifits

Sonkit Metal Comma Rings are designed for slow dynamic applications. The tightness with a Comma Ring is more than with any other metal seal a function of the shaft condition.
The surface finish of the shaft shall be mirror polished and the hardness shall be high enough so that the sliding motion of seal and shaft does not detoriate either of them. In addition we advise to silver plate Comma Ring for better tightness, reduced friction and wear.
