Rubber Bumper DE (Double Female) – Dual Internal Thread Vibration Mounts
Precision machinery and high-end enclosures often require a vibration isolation solution that remains entirely flush with the mounting surface. The Rubber Bumper DE (also known as Type DE) is engineered specifically for these clean-line applications. Featuring a dual internal (female) thread design, the DE series allows for symmetric fastening from both ends without any protruding studs. This makes it the premier choice for medical diagnostic equipment, laboratory instrumentation, and electronic rack systems where external aesthetics and space optimization are critical.
Xiamen Best Seal manufactures the Type DE double female bumper using high-resilience Natural Rubber (standard 55A Shore) molecularly bonded to precision metal inserts. The dual blind-hole design ensures that no dust, fluids, or contaminants can pass through the isolator, maintaining the structural integrity of your enclosure. Operating from a UL Certified Facility and maintaining production Aligned with IATF 16949 Standards, we provide the zero-tolerance thread alignment required for seamless integration into high-speed automated assembly lines.

Why elite OEMs specify the DE series for their high-precision assemblies:
🏗️ Dual-Ended Structural Stability
The Rubber Bumper DE allows for dual-sided bolting, creating a highly stable "bridge" between two surfaces. This symmetric fastening is essential for maintaining the axial alignment of sensitive components in optical and laser systems.
🛡️ 100% Flush Exterior Finish
By utilizing internal threads on both ends, the Type DE vibration isolator eliminates the need for external nuts or protruding studs. This provides a professional, "factory-finished" look to high-end medical carts and consumer electronics.
🔄 Contaminant Barrier
Our double female rubber mounts feature blind-hole threading. This creates an airtight and watertight seal between the two mounting points, protecting internal electronics from environmental humidity and chemical exposure in lab settings.

Rubber Bumper DE FAQ
❓ Why is the DE model better for symmetric mounting than Type B or C?
The Rubber Bumper DE provides internal threads on both ends, allowing the isolator to sit perfectly flush between two parallel plates. This symmetry ensures that the center of gravity and the vibration axis remain aligned, which is critical for precision instruments like optical scanners.
❓ Can you customize the thread depth (L) for the DE series?
Yes. While our standard double female rubber mounts follow the metric matrix, we can customize the internal metal inserts to provide specific thread depths or different thread pitches (UNF/UNC) to match your proprietary assembly hardware.
