Compact and suited to lighter, vibration-sensitive installations, the OSM25-C is a Type C open spring mounting with a 51 mm (A-dimension) footprint and a maximum load capacity of 25 kg. Designed for applications where high deflection and low natural frequency are required, this mount delivers up to 23 mm of working deflection, making it a considered choice where sensitive equipment or surrounding structures demand effective low-frequency isolation without the bulk of larger-capacity units. Constructed with rubber-to-metal bonded assembly, the OSM25-C accepts loading in shear, compression, or a combination of both. Its open spring configuration exposes the coil for straightforward inspection and, where conditions call for it, replacement. Key dimensional references are: A 51 mm, B 73 mm, D 70 mm, E 106 mm, F 11×16 mm, and CF 80. Custom variants in stainless steel metals or oil-resistant and high-temperature rubbers are available on request for demanding environments. This mounting suits lower-load scenarios across a broad spread of industries including construction and off-highway, agriculture, power generation, marine, railway and mass transit, and automotive applications. By absorbing vibrational energy at the source, the mount protects surrounding structures, extends machinery service life, and contributes to improved operator comfort, benefits that are especially relevant in compact or precision-sensitive plant layouts where mass or footprint is a design constraint. The OSM25-C forms part of a wider open spring mounting range.

A. The OSM25-C has a maximum load capacity of 25 kg and a working deflection of 23 mm.
A. The principal dimensions are: A 51 mm, B 73 mm, D 70 mm, E 106 mm, F 11×16 mm, and CF 80. The C dimension is not specified for this type.
A. The open spring mounting family is used across construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence applications — wherever high deflection and low natural frequency isolation are required.
A. Yes. The mount may be loaded in shear, compression, or a combination of both, as stated in the product specification.
A. Open spring mountings are suited where high deflection and a low natural frequency are required. The 23 mm deflection of the OSM25-C at its 25 kg rated load is particularly relevant for lighter, vibration-sensitive equipment where effective low-frequency isolation is the priority.
A. Yes. Stainless steel metals and oil-resistant or high-temperature rubbers, as well as additional and custom sizes, are available on request.
A. Yes. The range includes variants such as the OSM15-A, OSM15-B, OSM15-C, OSM100-A, OSM100-B, OSM100-C, OSM125-B, and OSM125-C, covering different load and deflection characteristics.
