Product Number: OSMHD300-B
Variations
Rated at a maximum load of 300 kg with 25 mm deflection, OSMHD300-B is an open spring mounting built for demanding high-load and shock-duty installations where conventional mounts would be overstressed. With an overall height of 128 mm (dimension E), a base diameter of 86 mm (dimension D), and an M12 threaded connection, this Type B mount occupies a well-defined footprint while delivering the high-deflection, low-natural-frequency isolation characteristic of the open spring design. Rubber-to-metal bonded construction combines a steel spring carrier with bonded rubber elements that may be loaded in shear, compression, or a combination of both. This construction reduces transmitted vibration, protects surrounding structures from fatigue, and extends machinery service life. The open-frame format allows visual inspection of the spring element without dismantling, a practical advantage in scheduled-maintenance environments. At 69 mm across the mount face (dimension A) and 113 mm for dimension B, with a centring flange dimension CF of 96 mm and a fixing slot of 11×20 mm, OSMHD300-B sits in the upper range of the open spring mounting series, suited to heavy plant, power generation sets, marine auxiliary machinery, railway and mass-transit equipment, and military and defence platforms where load and shock inputs are substantial. Agricultural and construction machinery operating in off-highway conditions also represent typical deployment contexts. Custom variants in stainless steel or oil-resistant and high-temperature rubber compounds are available on request.
