Product Number: OSM50-B
Variations
Compact in footprint yet capable of 23mm deflection, the OSM50-B Open Spring Mounting is engineered for low-frequency vibration isolation in lighter-duty and space-sensitive installations where high deflection relative to load is the priority. With a maximum load rating of 50 kg and a Type B geometry measuring 51mm (A) across the top plate and 72mm (B) overall width, this mount suits applications where isolating low-amplitude, low-frequency excitation from surrounding structures is essential. Constructed with rubber-to-metal bonded technology, the OSM50-B delivers reliable isolation in shear, compression, or combined loading orientations. The M8 fixing thread (dimension C) provides straightforward integration into equipment frames and base structures. Key envelope dimensions include a 70mm D measurement, 106mm E height, and an 11×16mm F slot, with a 80mm CF figure completing the mounting geometry. Custom stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for demanding environments. The open spring mount design is suited to machinery operating under normal working conditions where deflections up to approximately 20mm are typical, with this mount capable of reaching 23mm at rated load. Applications span power generation sets, agricultural machinery, light construction plant, marine auxiliary equipment, and railway ancillary units, anywhere that protecting sensitive supporting structures or reducing operator-perceived vibration is a primary objective. This mount is part of a broad open spring mounting range. For higher-load requirements, see the OSM100-A, OSM100-B, OSM100-C, OSM125-B, and OSM125-C variants. For smaller or alternative configurations, the OSM15-A, OSM15-B, and OSM15-C mounts are also available.

A. The OSM50-B has a 51mm top-plate dimension (A), 72mm overall width (B), M8 thread (C), 80mm CF, 70mm D, 106mm E height, and an 11×16mm F slot. It is rated to a maximum load of 50 kg with 23mm deflection.
A. The OSM50-B may be loaded in shear, compression, or a combination of both, giving flexibility in how it is installed within equipment frames and base structures.
A. This mount is designed for low-frequency vibration isolation under normal working conditions, with applications across power generation, agriculture, marine auxiliary equipment, light construction plant, and railway ancillary units — particularly where protecting surrounding structures or improving operator comfort is important.
A. It uses rubber-to-metal bonded construction, which ensures the rubber element remains securely integrated with the metal hardware throughout its service life.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.
