Failure Analysis of Rubber Friction Blocks Under Long‑Term Compression and Abrasion Conditions

Abstract: Rubber friction blocks are core functional components widely applied in mechanical transmission, braking systems, industrial damping equipment, and engineering machinery. These components consistently serve under complex coupling conditions of static and dynamic compression, cyclic friction, and continuous abrasion during long‑term service. With the extension of service time, multiple failure phenomena such as surface wear, […]

Design Essentials for Rubber Positioning Blocks Used for Limit and Shock‑Absorbing Applications

Rubber positioning blocks are ubiquitous passive mechanical components widely integrated into industrial automation machinery, transportation equipment, precision fixtures, and structural isolation systems. Primarily engineered for two core functions—hard travel limiting and passive shock absorption—these elastomeric components restrict excessive mechanical displacement, buffer instantaneous impact energy, and suppress continuous vibration transmission. Unlike rigid metal limit stops that […]
