Product Number: PR757040-70
Where duty cycles demand the highest load tolerance and the least permissible movement, the 70 Shore A profiled bobbin mount PR757040-70 answers with a rated maximum load of 357 kg and a rubber-to-metal bonded construction engineered to hold fast under shock and impact. With an outer diameter of 75 mm, a secondary diameter of 70 mm, and a height of 40 mm, this mount occupies a firm position in the upper reaches of the PR75x70x40 range, suited to installations where softer grades would over-deflect or fail to provide the structural restraint required. The dual M12 thread configuration (M12x37 stud on the primary face, M12 thread on the secondary face) allows direct in-line fitment between machine and chassis without adaptor hardware. The rubber compound is bonded under compression to the metal inserts, creating a load path that can be applied in shear, compression, or a combination of both, giving engineers flexibility in mounting orientation without sacrificing the restraint characteristics that define this hardness grade. At 70 Shore A, the rubber resists deflection under heavy or oscillating loads, making this mount appropriate for diesel engine installations, industrial machinery subject to cyclic shock, generator sets operating at sustained output, and exhaust system mountings that must remain positionally stable. The firm compound is the correct selection where the priority is limiting movement and preventing metal-to-metal contact under high dynamic load rather than maximising vibration attenuation at low amplitudes.

A. The PR757040-70 has a rated maximum load of 357 kg, placing it at the upper end of the 75 mm profiled bobbin range and making it suitable for heavy-duty machinery and engine mounting applications.
A. The outer diameter (D1) is 75 mm, the secondary diameter (D2) is 70 mm, and the height (H) is 40 mm. The primary thread is M12x37 and the secondary thread is M12.
A. At 70 Shore A, this is the firmest grade in the series. It carries higher loads with less deflection and provides greater positional restraint under shock and impact. Softer grades (45 Shore A or 60 Shore A) offer greater vibration isolation but are suited to lighter loads where movement under load is more acceptable.
A. The rubber-to-metal bonded construction allows loading in shear, compression, or a combination of both, giving flexibility in how the mount is oriented within the installation.
A. Source-confirmed applications include diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and air-conditioning units. Industries served include power generation, construction and off-highway, agriculture, marine, automotive, and railway and mass transit.
A. Yes. The same 75x70x40 mm M12 geometry is available in 45 Shore A (PR757040-45) and 60 Shore A (PR757040-60), allowing selection of the hardness grade best matched to the load and isolation requirement.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
