GVV Type Cylindrical Mounts

Waisted cylindrical mounts outperform standard cylindrical designs in terms of fatigue resistance under repeated dynamic loads. The waisted rubber profile, with its hourglass-like curvature, promotes even distribution of internal stresses during operation. This helps prevent the formation of micro-cracks and reduces the likelihood of rubber tear or material fatigue over time. In contrast, straight cylindrical mounts tend to experience higher stress concentrations near the bonded interfaces, which can lead to premature failure. The superior fatigue behavior of waisted mounts makes them especially reliable in applications with continuous start-stop cycles or high vibration duty, such as air compressors, industrial pumps, or automated manufacturing lines.

Thread-end bonding is a critical element in ensuring the mount's structural integrity under high-frequency, high-amplitude vibration. In waisted cylindrical mounts, the male studs are typically vulcanized directly into the rubber using precision-controlled steel-to-elastomer bonding during molding. This creates a unified, chemically bonded interface that resists pull-out forces and rotational stresses. In environments exposed to temperature changes, oil contamination, or high humidity—such as marine platforms, automotive engine compartments, or heavy industrial machines—poor bonding can lead to stud detachment or loosening over time. High-quality bonding not only improves safety and reliability but also reduces maintenance frequency and replacement costs, making it an essential design parameter for long-term use in vibration-critical systems.
