Precision Silicone Shim Washers

PEAK VN SERIES® | Ultra-Thin Alignment Solutions: 0.2 mm & 0.3 mm

The Micron-Level Standard (±20 μm / ±0.02 mm) for High-Precision Micro-Assemblies

Beyond the Red Line of Standard Industry Capabilities. In high-stakes engineering, a gap of 0.05 mm is the difference between a perfect assembly and a critical failure. While traditional metal or plastic shims are rigid and prone to deformation, PEAK VN Precision Silicone Shims provide the ultimate solution for micro-alignment, environmental sealing, and vibration isolation.

Dual-Phase Engineering: Shim & Washer Synergy

Our components are more than just washers; they are Precision Shims designed to:

Fill Micro-Gaps: Eliminate play between components in stacked assemblies.
Adjust Spacing: Achieve perfect alignment in optical and sensor modules.
Distribute Loads: Ensure uniform pressure distribution across delicate surfaces.
Isolate & Dampen: Provide electrical insulation and superior vibration damping that metal shims cannot offer.

Core Precision Specifications

Achieved exclusively through the PEAK-SPEC-020 manufacturing protocol:

The 0.20 mm Series (D-Series): The world-class benchmark for ultra-thin shimming (0.20±0.02 mm).
The 0.30 mm Series (W3/S3 Series): The gold standard for stability and micro-spacing (0.30±0.02 mm).
Material: High-Consistency Rubber (HCR) Silicone — Superior tear strength (21 kN/m) vs. LSR.
Tolerance: ±0.02 mm (Micron-level accuracy).
Thermal Range: -40° C to +250° C (HT Version).
