Product Number: OSM50-A
Variations
Compact and suited to lighter, vibration-sensitive installations, the OSM50-A is a 51mm open spring mounting with an M8 thread, rated to a maximum load of 50 kg and offering up to 23 mm of deflection under working conditions. This level of deflection is characteristic of the high-deflection, low-natural-frequency performance that open spring mountings are built to give, making the OSM50-A a practical choice where effective isolation of low-frequency vibration is the primary requirement. The mount employs rubber-to-metal bonded construction, allowing it to accept loading in compression, shear, or a combination of both. This construction approach contributes directly to improved machinery lifespan and protection of surrounding structures, whilst also supporting better operator comfort in installations where transmitted vibration would otherwise be a concern. Custom options, including stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes. Are available on request. The OSM50-A is applicable across many industries and operating environments. Source-confirmed sectors include construction and off-highway, power generation, marine, agriculture, and railway and mass transit applications, as well as automotive, military and defence use. The mount is intended for normal working conditions and should not be loaded beyond its specified 23 mm deflection limit. For heavier duty or larger-footprint requirements within the open spring mounting range, companion variants are available: OSM100-A, OSM100-B, OSM100-C, OSM125-B, OSM125-C, OSM15-A, OSM15-B, and OSM15-C. This product is supplied as a single open spring mounting unit. No warranty information is specified in the source data.
