Compact and precise, the OSM5-B is a Type B open spring mounting with a 51 mm base diameter and M8 thread, rated to a maximum load of 5 kg with a deflection of 23 mm. Designed for low-frequency vibration isolation where high deflection and a low natural frequency are required, this smallest mount in the open spring range is particularly suited to lighter, sensitive installations where controlled movement and isolation quality matter most. Constructed using rubber-to-metal bonded technology, the OSM5-B is capable of accepting load in compression, shear, or a combination of both. Its compact 51 mm diameter (dimension A), 72 mm height (B), and 106 mm overall dimension E keep installation footprints minimal without compromising isolation performance. The M8 thread centre fixing (C) and 11×16 mm slot (F) provide flexible mounting arrangements across a range of light-duty equipment. Maximum working deflection is 23 mm under a 5 kg load, consistent with the family design limit of approximately 20 mm for standard open spring types. Applications span industries where protecting sensitive plant or surrounding structures from low-frequency vibration is critical, including marine, power generation, agricultural machinery, and automotive installations. The OSM5-B improves machinery service life, shields adjacent structures from vibration transmission, and contributes to improved operator comfort in light-duty contexts. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request for demanding operating environments. This mount is the smallest in the open spring range.
