Rubber Vibration Isolator With External Thread

This composite structure features a trapezoidal elastomer section vulcanized to a bottom metal screw, creating a robust bond between the rigid connector and the flexible cushioning layer. The standard external threaded rod at the base screws directly into equipment bases or mounting plates, while the upper trapezoidal rubber block absorbs high-frequency vibrations and compensates for surface irregularities. Common applications include feet for automated production lines, supports for precision instruments, and vibration-damping mounts for motors.

The core of our manufacturing process lies in controlling the vulcanization bond strength at the rubber-metal interface to prevent debonding under long-term alternating loads. We also ensure strict coaxiality and thread precision for smooth, jam-free assembly. Equipped with flat and vacuum vulcanizing machines, we achieve a machining precision of ±0.05mm, effectively eliminating internal air bubbles and ensuring a dense, high-quality finish. Every batch undergoes full inspection for Shore hardness and tensile strength using vertical durometers and tensile testers to guarantee consistent physical performance.

Leveraging our in-house mold development capabilities, we offer rapid prototyping for non-standard specifications and support flexible delivery from small-batch trials to mass production. When purchasing, please provide detailed screw specifications (e.g., M6/M8), expected working loads, and environmental media requirements. This allows us to optimize material selection (such as oil-resistant or high-temperature formulations) and mold costs, delivering the best solution for your specific operating conditions.
