Product Number: 2520MM20-70
Variations
Compact yet capable of holding firm under load, the 25 x 20 mm male-male bobbin mount in 70 Shore A rubber is engineered for installations where keeping movement to a minimum is the priority. With a maximum load rating of 39.0 kg and a deflection of just 1.6 mm, SKU 2520MM20-70 delivers the tightest positional control within this bobbin diameter, making it well suited to lighter-weight assemblies that still demand firm restraint, exhaust mountings, instrument panels, and small generator sets where vibration-induced drift cannot be tolerated. Rubber-to-metal bonded construction joins the vulcanised 70 Shore A elastomer to both threaded steel studs (M8 x 20 mm) in a single, ready-to-fit unit. At this hardness grade the rubber resists deflection under repeated shock and impact loading, transmitting less movement to surrounding structures whilst absorbing energy that would otherwise cause fatigue or fastener loosening. The mount is usable in shear, compression, or a combination of both, giving engineers flexibility in how it is oriented within a mounting scheme. Applications across the family source include air-conditioning units, exhaust mountings, diesel engines, generator sets, instrumentation, and industrial machinery. At 70 Shore A the emphasis falls on firm retention of lightly massed components subject to sharp vibration or intermittent shock rather than on high-isolation compliance. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for demanding environments. This 25 x 20 mm diameter bobbin is also offered in 45 Shore A (2520MM20-45) and 60 Shore A (2520MM20-60) for softer deflection characteristics.

A. The mount has an outer diameter and height of 25 x 20 mm with M8 x 20 mm threaded studs. It is rated to a maximum load of 39.0 kg with a deflection of 1.6 mm at that load.
A. At 70 Shore A the rubber is the firmest grade in this bobbin range. It carries the highest load with the least movement — 39.0 kg maximum load and only 1.6 mm deflection — making it appropriate where positional stability and shock resistance matter more than soft isolation.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is oriented within an assembly.
A. The family source lists air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and industrial machinery and equipment as typical applications. At 70 Shore A the mount is particularly suited to installations requiring firm restraint under shock or repeated vibration.
A. Yes — the same 25 x 20 mm male-male bobbin is available in 45 Shore A (2520MM20-45) for greatest deflection and softer isolation, and 60 Shore A (2520MM20-60) as a mid-range option.
A. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, alongside additional and custom sizes.
