Product Number: 4020MM25-60
Balancing vibration isolation with structural support, the 40x20mm Male-Male Bobbin Mount in 60 Shore A rubber occupies the mainstream centre of the range, sKU 4020MM25-60 is dimensioned at 40mm diameter by 20mm height, carries a maximum load of 77.0kg per mounting, and delivers a controlled deflection of 1.6mm. The M10 x 25mm male-male thread configuration suits direct bolted installation without adaptors, making this the go-to choice for general-machinery mounting at moderate loads where neither excessive movement nor undue stiffness is appropriate. At 60 Shore A, this grade sits at the balanced mid-point of the hardness range: firm enough to manage the sustained loads common across industrial machinery and generator sets, yet compliant enough to attenuate moderate vibration and reduce transmitted shock to surrounding structures and operators. The rubber-to-metal bonded construction resists degradation under working conditions, and the mount can be loaded in shear, compression, or a combination of both, giving design and maintenance engineers flexibility in how the mount is oriented within an assembly. Typical applications drawing on the load capacity and moderate deflection of this grade include diesel engines, generator sets, air-conditioning units, industrial machinery and equipment, and exhaust mountings across industries such as power generation, agriculture, construction and off-highway, automotive, and marine. The 60 Shore A grade is particularly well matched to machinery running at moderate operating weights where consistent damping across a broad frequency range is more important than maximum isolation or maximum restraint.
Male Male Bobbins- also known as Type A Bobbins or Type 1 Bobbins. Low-cost Anti-Vibration solution for reducing vibration & shock. They can be used in either Shear or Compression or a combination and are available with various thread configurations. Additional Sizes are available, Plus Stainless-Steel metals and Oil Resistant / High Temperature rubbers available on request.
Applications include - General Purpose mountings, where a Male / Male Fixing is preferred. Popular in a wide range of applications & industries including Air Conditioning Units, Exhaust Mountings, Diesel Engines, Generator Sets, Instruments, Industrial Machinery & Equipment. Weight ranges from 1kg to 2000Kg per mounting.

A. The mount measures 40mm diameter by 20mm height (D x H), with M10 x 25mm male-male threads on both ends.
A. The 4020MM25-60 is rated to a maximum load of 77.0kg per mounting, with a deflection of 1.6mm.
A. At 60 Shore A, this mount offers a balance between vibration isolation and load-bearing support. Softer grades (such as 45 Shore A) provide greater deflection and better isolation at lower loads, while harder grades (such as 70 Shore A) carry higher loads with less movement. The 60 Shore A grade suits general-machinery mounting at moderate loads where consistent damping is the priority.
A. The mount can be loaded in shear, compression, or a combination of both, giving flexibility in how it is oriented within an installation.
A. Typical applications include diesel engines, generator sets, air-conditioning units, industrial machinery and equipment, and exhaust mountings. It is used across industries including power generation, agriculture, construction and off-highway, automotive, and marine.
A. Yes. The same 40x20mm geometry is available in 45 Shore A (SKU 4020MM25-45) and 70 Shore A (SKU 4020MM25-70). Other sizes in the family include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44.
A. Yes — stainless steel fittings and oil-resistant or high-temperature rubber compounds are available on request for applications requiring enhanced chemical or thermal resistance.
