EA560
Versatile Mechanical Seal
The EA560 is self-adjusting to shaft misalignments and deflections because of the loosely inserted seal face as well as the ability of the bellows to stretch and tighten. The length of the contact area of the bellows with the shaft is an optimum compromise between ease of assembly (less friction) and sufficient adhesive force for torque transmission.
Additionally the seal fulfills very specific leakage requirements.
Because the sliding parts are made in-house, a wide variety of special needs can be accommodated.
Feature
- Single seal
- Loosely inserted seal face provides selfadjusting capability
- In-house manufactured sliding parts

Operating range
This product is a mass production model and therefore it is not suitable for nuclear or aerospace applications as they require individual controls.
Applicable ranges, performance data and figures can serve only as a guide for selection and therefore in actual use there will be some cases where general specifications cannot be applied due to unknown factors or constraints.
Please check the applicability before use.
