Product Number: OSMHD250-B
Variations
Carrying a maximum load of 250 kg with a deflection of 25 mm, the OSMHD250-B is an open spring mounting designed to meet the demands of heavy-duty and shock-loaded machinery installations. Its rubber-to-metal bonded construction and open spring configuration deliver the high deflection and low natural frequency isolation that arduous industrial environments require, extending machinery lifespan while protecting surrounding structures and improving operator comfort. At Type B geometry with a 69 mm 'A' dimension, a 113 mm 'B' dimension, and M12 thread (C), the mount provides a CF figure of 96, 'D' of 86 mm, 'E' of 128 mm, and a slot dimension of 11×20 mm at 'F'. These proportions place the OSMHD250-B firmly in the upper band of the open spring mounting range, where the combination of high load capacity and controlled 25 mm deflection suits applications demanding both restraint and genuine vibration attenuation. The OSMHD250-B is suited to power generation plant, marine machinery, agricultural equipment, railway and mass transit installations, construction and off-highway machinery, automotive systems, and military and defence applications where high load and shock duty are the governing criteria. Mounts may be loaded in shear, compression, or a combination of both. Stainless steel metal parts and oil-resistant or high-temperature rubber compounds are available as custom options on request. This mount is part of a wider range of open and enclosed spring mountings. For lighter load capacities or alternative configurations, related variants include OSM100-A, OSM100-B, OSM100-C, OSM125-B, OSM125-C, OSM15-A, OSM15-B, and OSM15-C.
