With a rated maximum load of 500 kg with a deflection of 25 mm, the Type B open spring mounting OSMHD500-B sits at the upper end of this range and is engineered for heavy-duty, high-load and shock-duty isolation applications where conventional mounts would be insufficient. With an A dimension of 69 mm, B of 113 mm, D of 86 mm, E of 128 mm, CF of 96 mm and a fixing thread of M12 (F: 11x20), this mount is dimensionally specified for demanding installations across a broad spread of industries. Open spring mountings in this family use rubber-to-metal bonded construction and may be loaded in shear, compression, or a combination of both. They are designed for low-frequency isolation in normal working conditions, providing high deflection and a low natural frequency, characteristics that make them well suited to high-mass plant where dynamic forces are substantial. By absorbing and attenuating shock and vibrational energy, the mount extends machinery service life and protects surrounding structures from transmitted force. At this load and deflection rating, OSMHD500-B addresses heavy industrial requirements across power generation, marine installations, railway and mass transit, construction and off-highway equipment, and military and defence applications. Where the operating environment demands it, custom configurations using stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, as are additional and custom sizes. This product is part of a wider open spring mounting range.

A. The OSMHD500-B open spring mounting has a maximum load rating of 500 kg and a deflection of 25 mm.
A. The mount has an A dimension of 69 mm, B of 113 mm, D of 86 mm, E of 128 mm, CF of 96 mm, an F slot of 11x20, and an M12 fixing thread.
A. It uses rubber-to-metal bonded construction and can be loaded in shear, compression, or a combination of both.
A. This high-load mount is suited to power generation, marine, railway and mass transit, construction and off-highway, and military and defence applications where heavy-duty or shock-duty isolation is required.
A. Open spring mountings are designed for low-frequency isolation with high deflection and low natural frequency — characteristics required where conventional mounts cannot adequately attenuate the forces generated by heavy or shock-loaded machinery.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, as are additional and custom sizes.
A. Yes. The range includes lighter variants such as OSM15-A, OSM15-B and OSM15-C, mid-range options OSM100-A, OSM100-B and OSM100-C, and OSM125-B and OSM125-C for graduated load requirements.
