Product Number: 3040FF08-70
Variations
With a rated maximum load of 38.0 kg with a minimal deflection of just 3.6 mm, the 3040FF08-70 is the firm-grade member of the 30x40mm female-female bobbin mount family, engineered for installations where controlled movement and positive restraint take priority over isolation travel. Its 70 Shore A rubber compound delivers the stiffest response in this size range, making it the preferred choice where heavier loads must be held firmly in place and where shock or impact forces demand a mount that resists rather than absorbs movement. Constructed with rubber-to-metal bonding throughout, the 3040FF08-70 features a female-female thread configuration with M8 fixings on both faces. It may be loaded in shear, compression, or a combination of both, giving flexibility in mounting orientation. The firm rubber grade is suited to generator sets, diesel engines, and industrial machinery where high static loads act on compact mounting geometry. As with the wider family, the design simultaneously reduces vibration transmission to surrounding structures, extends machinery service life, and contributes to improved operator comfort. The 30 mm diameter by 40 mm height envelope keeps the package compact, and the M8 thread suits standard fastener tooling without adaptation. Applications across construction and off-highway equipment, power generation plant, and agricultural machinery are all well served by the 70 Shore A specification, particularly where the mounting must resist movement under sustained or intermittent shock loading. This SKU is available at 45 Shore A (3040FF08-45) and 60 Shore A (3040FF08-60) for installations requiring greater deflection and softer isolation.

A. The 3040FF08-70 is rated to a maximum load of 38.0 kg per mounting.
A. The deflection figure for this mount is 3.6 mm, reflecting the firm 70 Shore A rubber compound and its resistance to movement under load.
A. The mount has a 30 mm diameter by 40 mm height (D x H: 30 x 40) with M8 female threads on both faces.
A. The mount may be loaded in shear, compression, or a combination of both, depending on the installation geometry.
A. The firm 70 Shore A grade is best suited to applications carrying heavier or sustained loads where movement must be minimised — for example generator sets, diesel engines, industrial machinery, and construction or off-highway equipment subject to shock or impact forces.
A. Yes. The same geometry is available at 45 Shore A (SKU: 3040FF08-45) for maximum deflection and vibration isolation, and at 60 Shore A (SKU: 3040FF08-60) for general-purpose applications — choose the softer grade where lower loads and greater isolation travel are the priority.
A. Yes — stainless steel metal components, oil-resistant rubbers, high-temperature rubber compounds, and additional or custom sizes are available on request.
