In one paragraph: the JZP-1.0B-SC is a 46 mm rubber-to-steel isolator that carries 1.0 kg and puts its resonance at 41.5 ± 5 Hz. The elastomer profile was iterated in finite element analysis so working strain spreads across the whole rubber section instead of concentrating at the bondline, which keeps the frequency target stable batch after batch and keeps a mounted enclosure out of its amplification zone.
| Question a buyer usually asks | Answer for JZP-1.0B-SC | Condition behind the figure |
|---|---|---|
| How much mass can one unit support? | 1.0 kg nominal (9.8 N), ±5% | Static, pure vertical compression, 20 ± 5 °C |
| Where does it resonate? | 41.5 Hz, spread ±5 Hz | 5–50 Hz sine sweep at 0.5 g, 1 oct/min, single vertical axis |
| How far does it sink when loaded? | 0.3 mm or less | Read after 10 minutes of settling at rated load |
| What shock level has it passed? | 100 g peak, 12 pulses | 11 ms half-sine, three axes, four pulses per axis, rigid base |
| Which thread does it take? | M4 internal, class 6H | Install torque capped at 3 N·m |
| How long does the part stay in tolerance? | 8 years storage validity | Unloaded, sealed carton, below 30 °C |
All six answers are the controlled JZP-1.0B-SC values from the JZP-B-SC selection sheet. Nothing on this page is rounded up, re-rated or extrapolated from a sister model.
Each line states the number, the unit it is measured in, the tolerance band that governs acceptance, and the condition that produced it. Where a figure is a design floor rather than a measurement, the last column says so plainly.
| Parameter | Value | Unit | Tolerance / limit | How it is established |

Buyers regularly confuse the band they should design into with the band the lab sweeps. They are printed side by side here so the difference survives being copied into a specification.
Single-axis vertical sine sweep, 0.5 g, one octave per minute, 1.0 kg steel block on a ground fixture, ambient 20 ± 5 °C.
Its only job is to locate fn and record transmissibility. The sweep window is a bench setting, never a service recommendation, and the two must not be quoted interchangeably in a tender document.
Both figures trace to the same unit at the same preload; they differ in purpose, not in measurement.
Frequency is a design output, not a lucky accident. Compound hardness, insert geometry and bondline thickness are treated as one controlled set on this part. That is why the resonance of a delivered unit stays inside 41.5 ± 5 Hz instead of drifting with cure variation. When the excitation of a fan, a servo drive or a road input is known, the ratio between that excitation and 41.5 Hz decides whether the mount helps or hurts — and that ratio is knowable before the first prototype.
Stress distribution was solved before tooling. Finite element iterations moved peak strain off the insert corner and into the bulk of the elastomer, so a combined compression-and-shear event no longer starts a tear at the spot where rubber meets metal. The practical outcome is a part that holds its stiffness through repeated shock rather than softening after a few hundred cycles.
