Product Number: 5030MM23-70
Variations
With a rated maximum load of 173.0 kg with a controlled deflection of just 2.5 mm, the 5030MM23-70 is a firm-grade male-male bobbin mount engineered for applications where restraint and minimal movement take priority. The 70 Shore A rubber compound delivers the highest load resistance in this geometry's Shore range, making it the appropriate choice wherever heavier machinery must be held securely against shock, impact, or sustained compressive force. Rubber-to-metal bonded construction provides a direct, reliable bond between the elastomer and the threaded steel inserts, and the mount may be loaded in shear, compression, or a combination of both. The dual M8 x 23 mm male stud configuration allows straightforward in-line installation without additional hardware. The firm-grade rubber, while offering less isolation travel than softer variants, resists displacement under high load, a characteristic that is essential when structural control of the mounted assembly is as important as vibration attenuation. This mount is well suited to diesel engines, generator sets, industrial machinery and equipment, and exhaust mountings where vibration energy is high and positional stability of the unit is critical. It also finds application in construction and off-highway plant, power generation installations, marine machinery, and agricultural equipment operating under demanding duty cycles. The bobbin geometry supports a weight range that spans from light instruments up to 2,000 kg per mounting across the wider family. This SKU is part of a graded Shore range sharing the 50 x 30 mm, M8 x 23 mm geometry.

A. The 5030MM23-70 is rated to a maximum load of 173.0 kg with a deflection of 2.5 mm under load, reflecting the high load capacity and minimal movement characteristic of the 70 Shore A firm-grade rubber.
A. The mount features dual M8 male studs, each with a thread length of 23 mm, within a 50 mm diameter by 30 mm height body.
A. The firm 70 Shore A grade is best suited to applications requiring positional control under high load or shock — including diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and heavy-duty plant in construction, power generation, marine, and agricultural sectors.
A. This bobbin mount may be loaded in shear, compression, or a combination of both, giving flexibility in mounting orientation.
A. Harder Shore grades carry a higher load with less movement; softer grades provide greater deflection and better vibration isolation at lower loads. The 70 Shore A grade therefore prioritises restraint and load capacity over maximum isolation travel.
A. Yes — stainless steel metals and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
