Selection and installation fundamentals

The homepage presents representative data. Final dimensions, load ranges and model selection should be confirmed against the corresponding catalog page and project conditions.

Dahe building vibration isolation applications
Selection guide

How to select a spring isolator

Determine total equipment and base weight W, divide by the support count N for point load P=W/N, then use operating speed, target isolation efficiency, natural frequency and deflection to identify the model.

View catalog selection guide
01

Check the foundation level

Confirm that the concrete base or machine frame is level and verify support quantity and fixing holes.

02

Verify actual compression

JA/JB products commonly use approximately 20–30 mm compression and ZTA about 15–25 mm, subject to the model table.

03

Lock fasteners after leveling

Retighten frame and locking bolts after leveling and check that the isolators carry load evenly.
