Simmerring® MRO Toolkit

Simmerrings are durable and versatile components, whose functionality depends to a great extent upon their being properly installed. Thus, for example, up to 30% of early failures of rotary shaft seals are traceable to faulty installation. Simrit® has now developed an assembly set that minimises installation errors and simplifies deinstallation.

MRO Toolkit


The disassembly tool makes possible the gentle removal of Simmerrings. It consists of a slide hammer, two extensions and tapping screws.


The tools especially developed for this purpose make possible the damagefree installation of Simmerrings. Simply select the appropriate protective rim, based on the dimension, and insert the Simmerring® securely and carefully in the borehole.
