Key Facts at a Glance

Why the Self-Locking Fastener Interface Matters

Transverse vibration is what loosens bolts. Each cycle lets the joint slip a fraction of a micron, preload decays, and after a few thousand cycles the fixing that was torqued on the line is no longer clamping anything. On a 2.5 kg mount that shows up as a rattle, a shifting cabinet, or an electrical fault that only appears while the machine is running.

What the integrated locking interface provides

• Preload retention under excitation. The M4 thread pair is built to hold clamp load through continuous dynamic loading, so the joint does not walk loose between service intervals.
• One less consumable. No thread-locking fluid, no split washer and no secondary retaining strap, which removes an assembly step, a cure time and a quality check per mount.
• Shock-proven. The interface is qualified together with the body at 100 G for 12 successive shocks, so transport shock and start-stop cycles act on the same joint that was validated.
• Re-serviceable. The mount can be released and re-fitted during maintenance without destroying the locking feature, which keeps the spare-part number unchanged.

Performance Parameters

Frequency Definitions: Recommended Operating Band and Test Sweep Range

Two different numbers describe the frequency behaviour of the JZP-2.5B-SC, and they answer different questions. One tells a designer where the mount may be used; the other only records how the natural frequency was measured during qualification. Mixing them up is a common cause of a mount that appears to amplify vibration instead of reducing it.

Choosing the Right Load Rating in the Series

All ten models share one drawing. Only the compound hardness changes, which is why the load rating is the only variable a designer has to settle.

Selection in four steps

1. Add the equipment mass to the bracket mass to get the total payload.
2. Divide by the number of mounts, then apply 1.2–1.5 as a dynamic margin for start-stop and transport loads.
3. Round down to the nearest rating in the table: a 2.2 kg result stays on JZP-2.5B-SC, a 2.7 kg result moves up to JZP-3.0B-SC.
4. Check the excitation frequency against the 29–59 Hz amplification band; if the disturbance sits there, change the layout or the rating rather than accepting the mount.

Storage, Service and End of Life

• Storage: keep in the original bag, away from direct sunlight, ozone sources such as electric motors, and solvent vapours; 10–30 °C and below 70 % RH. The 8-year valid period counts from commissioning, not from the production date.
• Inspection: check preload and elastomer appearance every 12 months, or every 6 months above +50 °C. Look for cracking at the fillet, permanent set, or a shiny contact line between rubber and metal.
• Replacement: replace when static deflection has grown visibly, when the rubber shows cracks deeper than the fillet radius, or after a shock event above the 100 G qualification level.
• End of life: the aluminium base and the steel insert are separated from the elastomer and go to normal metal recycling; the compound carries no halogenated plasticiser.
