Product Number: 4035MM25-70
Variations
The 4035MM25-70 is a firm-grade, rubber-to-metal bonded male-male bobbin mount rated to carry up to 78.0 kg with a controlled deflection of just 3.1 mm, figures that place it firmly in the higher end of its geometry class and make it the specification of choice where loads must be held with minimal movement. At 40 mm diameter by 35 mm height with M10 x 25 mm threaded studs on both faces, this mount slots directly into standard male-male bobbin positions across many general industrial machinery. Constructed with rubber-to-metal bonding throughout, the 70 Shore A hardness grade is engineered to manage shock and impact loading rather than absorbing fine vibration. Where softer grades prioritise isolation and deflection, this firm grade maintains positional stability under heavier loads, resisting unwanted movement and protecting surrounding structures from transmitted force. Loadings may be applied in shear, compression, or a combination of both, giving engineers flexibility in how the mount is orientated and utilised. The 4035MM25-70 is suited to applications where robust restraint is the priority: generator sets operating under load variation, diesel engines subject to torque impulses, exhaust mounting systems, and general industrial machinery and equipment in sectors including power generation, construction and off-highway, agriculture, marine, and automotive. It contributes to improved machinery lifespan and reduced structural fatigue across demanding operational environments.

A. The mount measures 40 mm diameter by 35 mm height (D x H), with M10 x 25 mm threaded studs on both faces (d x L). Maximum load capacity is 78.0 kg with a deflection of 3.1 mm at that load.
A. This mount is supplied in 70 Shore A rubber. At this hardness, the mount carries higher loads with less movement compared to softer grades — making it appropriate for applications where positional stability, shock absorption, and firm restraint are priorities over maximum vibration isolation.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in mounting orientation to suit the specific application.
A. The 70 Shore A grade is particularly suited to generator sets, diesel engines, exhaust mounting systems, and general industrial machinery and equipment where heavier loads and resistance to shock or torque impulses are the primary concern. It is also used across construction and off-highway, agricultural, marine, automotive, and power generation applications.
A. Yes — the same 40 x 35 mm male-male bobbin geometry is available in 45 Shore A (SKU 4035MM25-45) and 60 Shore A (SKU 4035MM25-60). Softer grades offer greater deflection and improved isolation at lower loads.
A. Yes — stainless steel hardware and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
