JZP-10.5 Rubber Shock Absorber Mount 3D Multidirectional Load Absorption

Product Specification

JZP-10.5 Multidirectional ESD-Safe Vibration Isolator

The JZP-10.5 addresses a specific challenge in precision manufacturing and electronics environments: the need for vibration isolation that works from any direction while safely dissipating electrostatic charges that could damage sensitive components. Its domed elastomer geometry and conductive compound formulation make it the go-to choice for semiconductor tools, inspection equipment, and server infrastructure where ESD events can cause millions in downtime.

How 3D Multidirectional Absorption Works

Unlike conventional cylindrical mounts that excel in axial compression but stiffen dramatically under shear and buckling loads, the JZP-10.5 employs a spherical sector elastomer profile. This geometry provides nearly isotropic stiffness — meaning the mount's response is comparable whether vibration arrives axially, radially, or at any oblique angle. The rubber element deflects in compression-shear combined mode, absorbing energy through hysteretic damping across all three translational axes simultaneously. In testing, the JZP-10.5 achieved vibration transmission loss rates of 82-85% across a 10-500 Hz excitation bandwidth when loaded to 50-70% of rated capacity.

ESD Protection Mechanism

• Conductive Carbon Network — The NR/CR base polymer is loaded with high-structure conductive carbon black at a volume fraction above the percolation threshold, forming continuous conductive pathways through the elastomer matrix without compromising mechanical properties.
• Surface Resistivity 10⁴-10⁶ Ω — Positioned in the static-dissipative sweet spot: conductive enough to bleed off charges within milliseconds (meeting ANSI/ESD S20.20 requirements of < 2 seconds decay time from 1000V to 100V), yet resistive enough to prevent dangerous current flow in the event of accidental contact with live circuits.
• Permanent Antistatic Property — Unlike topical antistatic sprays that wear off with handling and cleaning, the carbon-filled compound provides permanent, humidity-independent ESD protection throughout the product's service life.

Production & Compliance

• Controlled Mixing Environment — Carbon black dispersion is achieved via two-pass internal mixing (Banbury type) with real-time power curve monitoring to verify dispersion quality. Poor dispersion leads to resistivity hotspots, so each batch undergoes inline resistivity coupon testing before molding.
• IEC 61340-5-1 Compliance — Our ESD control program follows the international standard for protection of electronic devices from electrostatic phenomena. Documentation packages including compliance certificates and batch resistivity logs are available with each shipment.
• Traceability — Every production lot is assigned a unique batch code traceable to raw material lots, mixing parameters, molding press records, and QC test data held for 36 months.

Installation & Maintenance

• Ensure the mounting surface is electrically connected to the facility's ESD grounding network (recommended: < 1 Ω to ground)
• Periodically verify surface resistivity with a calibrated megohmmeter per IEC 61340-2-3 — recommended interval: every 6 months or 2000 operating hours
• Do not paint, coat, or apply adhesive to the rubber surface, as this will compromise conductivity
• Clean only with isopropyl alcohol and a lint-free wipe; solvent-based cleaners may extract antistatic additives
• Replace mounts showing physical cracks, permanent set exceeding 15% of original height, or resistivity measurements outside the 10⁴-10⁶ Ω range

Industry Applications

• Semiconductor Fabrication — Wafer handling robots, lithography tool isolation, CMP machine vibration damping in Class 100/1000 cleanrooms
• SMT Assembly Lines — Pick-and-place machine feet, reflow oven conveyor isolation, AOI inspection station mounting
• Data Center Infrastructure — Server rack base isolation, HDD array vibration decoupling, CRAC unit mounting to prevent structure-borne noise
• Medical & Laboratory — Centrifuge vibration isolation, electron microscope base mounting, precision balance tables, PCR thermal cycler platforms
• Test & Measurement — Coordinate measuring machine (CMM) foundations, laser interferometer tables, vibration-sensitive metrology equipment

Comparative Advantage

Conventional vibration mounts require separate grounding straps or conductive mats to address ESD concerns — adding cost, installation complexity, and potential failure points. The JZP-10.5 integrates vibration damping and static dissipation into a single compact unit, reducing BOM count and simplifying assembly for OEM equipment builders. Its near-isotropic stiffness profile further eliminates the need for orientation-specific mounting, enabling faster and more forgiving installation on the production line.
