Product Number: OSMHD250-C
Variations
With a rated maximum load of 250 kg with 25 mm deflection, the OSMHD250-C is an upper-range open spring mounting engineered for demanding heavy-duty and high-shock applications where conventional mounts would be overloaded. Its Type C geometry, dimensioned at 69 mm (A), 115 mm (B), 96 mm (CF), 86 mm (D), 128 mm (E) and an 11×20 mm fixing slot (F). Provides the structural envelope needed to absorb severe dynamic forces across plant and machinery operating under sustained high loading. Rubber-to-metal bonded construction forms the basis of this mounting's durability. The open spring design is suited to installations where high deflection and a low natural frequency are required, making it appropriate for isolating low-frequency vibration sources that would otherwise transmit into surrounding structures or machine frames. The rubber element may be loaded in shear, compression, or a combination of both, giving specifiers flexibility in how the mount is orientated within a given installation. Applications drawing on this mount's high-load capacity include power generation sets, heavy agricultural machinery, marine auxiliary drives, and large off-highway or construction plant where both steady compression loads and intermittent shock loading must be managed simultaneously. By reducing vibration transmission, the mount contributes to extended machinery lifespan, protects adjacent structures, and improves operator comfort. Mounts in this family are suited to normal working conditions with deflection up to approximately 20 mm under rated load. Custom configurations, including stainless steel metalwork and oil-resistant or high-temperature rubber compounds. Are available on request for demanding environments.
