Product Number: OSM5-A
Variations
Compact at 51mm (dimension A) with an M8 fixing thread, the OSM5-A is an open spring mounting designed for light-load, low-frequency vibration isolation in installations where high deflection and a low natural frequency are required. With a maximum load rating of 5 kg and a deflection figure of 23mm, this is the smallest-capacity mount in the open spring mounting range, making it well suited to sensitive equipment, lightweight machinery, and applications where minimising transmitted vibration at lower loads is the primary concern. Constructed with rubber-to-metal bonded elements, the OSM5-A can be loaded in shear, compression, or a combination of both. This construction method provides reliable, consistent isolation performance across the rated deflection range without the risk of delamination under normal operating conditions. The open spring format is appropriate where low natural frequency isolation is the engineering priority and space envelopes are compact. The mount serves applications across a broad range of industries where protecting lightweight or sensitive equipment from structure-borne vibration is essential, including power generation, marine installations, agricultural machinery, and automotive applications. By isolating vibration at the source, it helps improve the operational lifespan of machinery, reduce fatigue loading on adjacent structures, and contribute to improved operator comfort. Custom configurations in stainless steel metalwork or oil-resistant and high-temperature rubbers are available on request. This mount is available in a wider range of load capacities and configurations. Complementary variants in this open and enclosed spring mounting family include OSM15-A, OSM15-B, OSM15-C, OSM100-A, OSM100-B, OSM100-C, OSM125-B, and OSM125-C.

A. The OSM5-A has a maximum load rating of 5 kg and a deflection of 23mm. It is the lightest-capacity mount in this open spring mounting range and is suited to lighter, more sensitive installations where high deflection and a low natural frequency are required.
A. The OSM5-A uses an M8 fixing thread. Dimension A is 51mm and dimension B is 70mm. Refer to the technical specification for full dimensional data.
A. The OSM5-A can be loaded in shear, compression, or a combination of both, giving flexibility in how it is oriented within an installation.
A. The mount uses rubber-to-metal bonded construction, which provides consistent performance and structural integrity throughout the rated deflection range under normal working conditions.
A. This mount is designed for use in power generation, marine, agricultural, automotive, and similar industries where isolating vibration from lightweight or sensitive equipment is essential. It is particularly appropriate where a low natural frequency and high deflection are required at lower load levels.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, as are additional and custom sizes. Contact the team to discuss requirements.
