Sensitive installations and lower-frequency applications demand a mount that prioritises isolation over restraint, and the 4028MM25-45 male-male bobbin mount is engineered precisely for that purpose. Rated to a maximum load of 35.0 kg with a deflection of 2.4 mm, this 40 x 28 mm unit fitted with M10 x 25 threaded studs occupies the softer end of the hardness range at 45 Shore A, a grade selected where maximum vibration absorption and compliance under load take precedence over stiffness. The 45 Shore A rubber compound delivers greater deflection and enhanced isolation characteristics compared with medium and firm grades of the same geometry, making it well suited to lighter or compact equipment where transmitted vibration could affect instrument accuracy, operator comfort, or the structural integrity of surrounding assemblies. The rubber-to-metal bonded construction is capable of accepting load in shear, compression, or a combination of both, a versatility that widens its scope across different mounting orientations without compromising isolation performance. Typical applications drawing on this grade's compliance include air-conditioning units, instrument mountings, and exhaust mountings on lighter plant, along with diesel engines, generator sets, and industrial machinery where low-frequency vibration isolation is the primary concern. The male-male stud configuration allows straightforward integration into existing sub-frames or fabricated brackets. Industries served include power generation, agriculture, construction and off-highway, marine, automotive, and railway and mass transit. Stainless steel metal parts and oil-resistant or high-temperature rubbers are available on request for demanding environments. This mount is part of a wider male-male bobbin range.

A. The 4028MM25-45 is rated to a maximum load of 35.0 kg with a deflection of 2.4 mm.
A. At 45 Shore A, this is the softer grade within the range. Softer grades produce greater deflection under load and deliver better vibration isolation, making them the preferred choice for lighter or sensitive equipment and lower-frequency isolation requirements where compliance matters more than restraint.
A. The outer dimensions are 40 mm diameter by 28 mm height. The threaded studs are M10 with a 25 mm engagement length.
A. The rubber-to-metal bonded construction allows the mount to be loaded in shear, compression, or a combination of both, giving flexibility across different installation configurations.
A. Source-confirmed applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and industrial machinery and equipment. The 45 Shore A soft grade is particularly well matched to lighter, compact, or vibration-sensitive installations.
A. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes. The 4028MM25-60 (60 Shore A) and 4028MM25-70 (70 Shore A) offer progressively higher load capacity and less deflection within the same 40 x 28 mm male-male geometry.
A. Stainless steel metal parts and oil-resistant or high-temperature rubbers are available on request for applications where the standard specification is not suitable.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).
