VD Rubber Mount (Double Male Stud) – High-Capacity Industrial Vibration Isolation
The VD Rubber Mount (also known as Type A) is the definitive pillar of industrial vibration control. Featuring dual galvanized steel studs molecularly bonded to a cylindrical rubber core, this double male mount provides a symmetric suspension solution for the world's most demanding machinery. From high-pressure air compressors and diesel power generators to heavy-duty industrial centrifugal pumps, the VD type is specified by engineers for its simplicity of installation and its exceptional ability to neutralize both axial and radial vibration frequencies.
Xiamen Best Seal manufactures the VD Rubber Mount series using high-rebound Natural Rubber (Shore 55A) and Grade 8.8 high-tensile hardware. Our manufacturing protocol, Aligned with IATF 16949 Standards, focuses on absolute axial concentricity. In a double-stud mount, even minor misalignment can lead to "built-in" stress during assembly, causing premature polymer failure. At our UL Certified Facility, we utilize precision cross-axis molding to guarantee that every double ended stud rubber buffer is perfectly centered, delivering stable dynamic performance and a extended service life for your rotating equipment.

Why the VD series is the volume-leader for global OEM assembly lines:
🏗️ High Load Linearity
The VD Rubber Mount exhibits highly linear damping characteristics in both compression and shear. This makes it the ideal choice for motors that experience high startup torque, as the symmetric double-stud design distributes the torsional load evenly across the entire elastomer surface.
🔗 Superior Adhesion Chemistry
A double male stud rubber buffer is only as strong as its bonding primer. We utilize proprietary heat-activated bonding agents and plasma-cleaned studs to ensure the metal-to-rubber interface can withstand forces that exceed the tensile strength of the rubber itself, preventing stud-pullout.
🔄 Seamless Assembly Interchangeability
The identical double studs of the VD mount simplify inventory and assembly. Technicians can install the mount in either direction, eliminating installation errors and speeding up production cycles in high-volume air compressor and pump manufacturing.

Strategic Support for Global Industrial OEMs
VD mounts are "commodity" items where consistency is the ultimate value. We safeguard your production through technical and data security:
📦 High-Volume Supply & Margin Protection:
- Annual Blanket Orders & Price Locking: For our high-volume HVAC and power-gen partners, we offer 12-month blanket order structures with fixed pricing. This protects your margins against hardware material (steel) and elastomer price fluctuations.
- Data-Sheet Synergy: We provide unbranded Technical Data Sheets (TDS) and 3D CAD files for every VD variant, allowing your engineering team to simulate stress and vibration damping performance before the first physical prototype arrives.
Industrial-Scale Vibration Isolator Manufacturing
★┊ Precision Through Automation
The VD Rubber Mount is the cornerstone of our manufacturing capacity. To serve the needs of global air compressor and generator brands, we utilize fully automated multi-cavity injection lines. Operating strictly under **Quality Protocols Aligned with IATF 16949 Standards**, we deploy automated visual inspection and cryogenic deflashing to ensure that every double-stud buffer is geometrically perfect and free of excess rubber "flash." This level of precision is why our components are selected as the Tier-1 standard for the world's leading industrial machinery assemblers.

VD Type Bobbin FAQ
❓ Why is Natural Rubber preferred for VD mounts over synthetic polymers?
Natural rubber possesses higher elasticity and superior dynamic resilience compared to most synthetics. In a VD mount, where the rubber is constantly under dual-ended load, natural rubber provides the necessary "memory" to return to its original shape, ensuring the machine's harmonic frequencies remain consistent over years of service.
❓ Can you provide VD mounts with different stud lengths on each side?
Yes. While symmetric studs are standard, many OEMs require specialized configurations (e.g., L1 = 15mm for a thin panel and L2 = 40mm to pass through a thick engine housing). As we control the assembly process from primer to press, we can customize hardware configurations for your specific platform without significant lead-time increases.
