Product Number: PR403528-70

Where load capacity and positional control take priority, the 70 Shore A profiled bobbin mount PR403528-70 delivers the firmest rubber grade available in this 40mm profiled geometry. With a maximum load rating of 62 kg per mounting and overall dimensions of 40 mm (D1) × 35 mm (D2) × 28 mm height, this rubber-to-metal bonded mount is engineered to carry heavier loads with minimal deflection, making it the right choice when the mounted component must be held firmly in position under sustained load or impact. The 70 Shore A rubber compound provides the least movement of any hardness grade in the profiled bobbin range. This firm characteristic is well suited to applications involving shock and impact loading, generator sets, diesel engines, and industrial machinery and equipment where operational forces are high and positional drift would be unacceptable. Thread configuration is M10×16 (Type d1), M10×20 (1 d1) and M10 (d2 / Type d2 / 3 d2), providing straightforward male–male or male–female installation flexibility. The mount may be loaded in shear, compression, or a combination of both. Rubber-to-metal bonded construction ensures bond integrity under the high-load and shock conditions this grade is designed for. Across the industries it serves, construction and off-highway, power generation, agriculture, marine, railway and mass transit, automotive, and military and defence. The 70 Shore grade is the appropriate specification wherever vibration isolation must be balanced against firm restraint and structural protection.

A. The PR403528-70 has a maximum load rating of 62 kg per mounting. As a 70 Shore A (firm) grade, it is designed to carry this load with minimal deflection, making it suitable for heavier or shock-loaded installations.
A. The mount measures 40 mm outer diameter (D1), 35 mm inner/lower diameter (D2), and 28 mm height (H). Thread configurations are M10×16 (Type d1), M10×20 (1 d1), and M10 (d2 / Type d2 / 3 d2).
A. Shore A is a measure of rubber hardness. At 70 Shore A, this is the firmest grade in the profiled bobbin range — it carries the highest load with the least deflection. Softer grades (45 and 60 Shore A) provide greater movement and better isolation at lower loads, while this 70 Shore A grade prioritises positional control and load-bearing under shock and impact conditions.
A. It is suited to applications where the mounted item must be held firmly under high or shock loads, including diesel engines, generator sets, and industrial machinery and equipment. It is also used across construction and off-highway, power generation, marine, agricultural, railway, automotive, and military and defence applications.
A. Yes. The mount may be loaded in shear, compression, or a combination of both, providing flexibility in how it is installed within a given assembly.
A. Yes. The same 40×35×28 mm profiled geometry is available in 45 Shore A (PR403528-45) and 60 Shore A (PR403528-60) for applications requiring greater deflection or lighter load capacity. Additional profiled bobbin sizes include PR1009555, PR1009575, PR262222, PR464025, and PR757040.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for applications requiring enhanced corrosion or chemical resistance.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
