Rubber Vibration Damping Bushing

When evaluating these annular elastic components, it is crucial to confirm the fit tolerance between the inner bore and the shaft system, as well as the spatial constraints of the outer diameter installation area. The black cylindrical structure shown features a central through-hole and symmetric notches or grooves on the side walls. This design is typically used for shaft positioning, gap filling, or vibration isolation in mechanical transmission systems, absorbing high-frequency impacts and compensating for assembly errors through the elastic deformation of the rubber material.

The core of manufacturing lies in controlling dimensional stability and appearance density during compression molding. For the notch structures on the side walls, the mold parting surfaces must be precisely matched to prevent flash overflow from affecting assembly. Simultaneously, Shore A hardness consistency must be strictly controlled to ensure stable rebound performance and resistance to compression set under various load conditions. The factory uses flat vulcanizing presses and vacuum vulcanization equipment for integrated molding, effectively eliminating internal bubbles and ensuring uniform physical properties.

Zhejiang Shunyi Rubber & Plastic leverages its self-developed mold development capabilities to quickly respond to non-standard specification mold opening requirements based on drawings or samples, supporting flexible delivery from single-piece prototyping to mass production. Combined with testing equipment such as vertical/handheld hardness testers and tensile testing machines, we perform full inspections of hardness range and tensile strength for each batch, ensuring compliance with ISO 9001 quality management system requirements. When requesting a quote, please specify the inner and outer diameter dimensions, notch position tolerances, and material media resistance requirements (such as oil-resistant NBR or weather-resistant EPDM) to optimize formula selection and calculate mold costs.
