Product Number: OSM125-B
Variations
Rated at a maximum load of 125 kg with a deflection of 23 mm, the OSM125-B is a Type B open spring mounting built to give effective low-frequency vibration isolation under mainstream general-machinery conditions. The 51 mm diameter and M8 fixing thread make this a practical mid-range solution where moderate-to-substantial loads must be controlled without resorting to heavy-duty hardware. Construction relies on a rubber-to-metal bonded assembly that can accept loading in compression, shear, or a combination of both. The open-spring format is suited to installations requiring high deflection and a low natural frequency, characteristics that reduce transmitted vibration to surrounding structures, extend machinery service life, and contribute to improved operator comfort. Custom variants in stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request. With principal dimensions of 51 mm (A), 72 mm (B), 70 mm (D) and 106 mm (E), along with a 11×16 mm slot (F) and a 80 mm centring flange (CF), the OSM125-B suits a broad cross-section of general industrial and rotating-machinery applications. Industries that routinely specify open spring mountings of this type include power generation, agriculture, construction and off-highway, marine, and automotive. The OSM125-B sits within a wider family of open spring mountings available in multiple sizes and load ratings. Related variants include the lighter-duty OSM15-A (OSM15-A), OSM15-B (OSM15-B) and OSM15-C (OSM15-C), the OSM25-A (OSM25-A), the OSM100-A (OSM100-A), OSM100-B (OSM100-B) and OSM100-C (OSM100-C), and the higher-capacity OSM125-C (OSM125-C). This mounting is supplied as a single unit.

A. The OSM125-B is rated to a maximum load of 125 kg with a deflection of 23 mm under normal working conditions.
A. The principal dimensions are: A = 51 mm, B = 72 mm, D = 70 mm, E = 106 mm, F = 11×16 mm slot, and CF = 80 mm. The fixing thread is M8.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is installed within a machine assembly.
A. It provides low-frequency vibration isolation by operating at high deflection and low natural frequency, which reduces vibration transmitted to surrounding structures, helps protect adjacent equipment, and improves operator comfort.
A. Open spring mountings of this type are used across power generation, agriculture, construction and off-highway, marine, and automotive applications, as well as in railway and mass transit, military and defence, and general industrial machinery.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request, along with additional and custom sizes.
A. The family includes the OSM15-A, OSM15-B, OSM15-C, OSM25-A, OSM100-A, OSM100-B, OSM100-C, and the higher-capacity OSM125-C, covering a range of load requirements and fixing configurations.
