Product Number: OSM25-A
Variations
Compact and light-duty by design, the OSM25-A is a Type A open spring mounting with a 51mm body diameter, M8 thread fixing, a maximum load capacity of 25kg, and a rated deflection of 23mm, making it well suited to sensitive or lightly loaded installations where controlled low-frequency vibration isolation is the priority. Built with rubber-to-metal bonded construction, this open spring mount accommodates loading in shear, compression, or a combination of both. The design allows the high deflection and low natural frequency characteristics required in applications where conventional rigid mountings would transmit unwanted vibration to surrounding structures or operators. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request. The OSM25-A is suited to environments such as power generation, marine installations, agricultural machinery, and light industrial plant, wherever compact footprint and lower load duty call for precise isolation without over-engineering the mounting arrangement. Its 23mm deflection figure supports effective attenuation of low-frequency excitation sources common in these settings. By reducing transmitted vibration, the mount contributes to improved machinery lifespan, protection of surrounding structures, and enhanced operator comfort. This mount is part of a broader range of open spring mountings. Sibling variants include OSM15-A, OSM15-B, OSM15-C, OSM100-A, OSM100-B, OSM100-C, OSM125-B, and OSM125-C, covering a spectrum of load capacities and configurations to suit varied installation requirements. The OSM25-A is supplied as an individual mounting unit. No warranty information is specified for this product. Manufactured in the United Kingdom.
