Where loads must be held firmly and movement kept to a minimum, the 30x25mm Male-Male Bobbin Mount in 70 Shore A (SKU: 3025MM20-70) delivers the highest load resistance and lowest deflection in its geometry class. Rated to a maximum load of 40.0 kg with a deflection of just 2.1 mm, this firm-grade mount is the correct choice when shock absorption and positional restraint take priority over isolation travel, suited to heavier compact installations where structural integrity under impact matters. Rubber-to-metal bonded construction gives this bobbin mount the rigidity needed for demanding duty cycles. The 70 Shore A rubber resists deformation under sustained load and repeated shock, making it the most capable grade in the 30x25mm range for applications where softer mounts would allow excessive movement. The male-male thread configuration, m8 with 20 mm stud length on both ends. Allows direct in-line installation between mounting faces without additional hardware. Custom configurations using oil-resistant or high-temperature rubbers, as well as stainless steel metalwork, are available on request. Typical applications served by firm-grade bobbin mounts of this type include diesel engine mounts, generator set installations, industrial machinery and equipment, exhaust mountings, and air-conditioning units, wherever a compact rubber mount must handle concentrated load or intermittent shock in the construction and off-highway, power generation, marine, automotive, or agricultural sectors. The rubber-to-metal bond protects surrounding structures, improves machinery lifespan, and reduces transmitted vibration to the supporting frame. This mount is part of a broad male-male bobbin range.

A. This mount is rated to a maximum load of 40.0 kg with a deflection of 2.1 mm. The 70 Shore A hardness grade is designed to carry higher loads with minimal movement, making it suitable for applications where positional restraint and resistance to shock are the primary requirements.
A. The mount uses an M8 male thread on both ends, with a stud length of 20 mm per side. The male-male configuration allows direct in-line fitting between two mounting faces without additional adaptors.
A. The body measures 30 mm diameter by 25 mm height (D x H: 30 x 25 mm), providing a compact footprint suitable for space-restricted installations.
A. Shore A hardness governs the trade-off between load capacity and deflection travel. The 70 Shore A grade carries the highest load and produces the least deflection — correct for heavier loads, shock or impact duty, and where the mounted item must be held firmly. The 45 Shore A (3025MM20-45) and 60 Shore A (3025MM20-60) variants of this geometry give greater deflection and better vibration isolation at lower loads.
A. Bobbin mounts of this type may be loaded in shear, compression, or a combination of both, giving installation flexibility depending on the orientation and load path in the application.
A. Suitable applications include diesel engine mounts, generator set installations, exhaust mountings, air-conditioning units, and industrial machinery and equipment. Industries served include construction and off-highway, power generation, marine, automotive, agricultural, and railway sectors.
A. Yes. Oil-resistant rubbers, high-temperature rubbers, stainless steel metalwork, and additional or custom sizes are available on request.
