Product Number: PR464025-45
Variations
Soft-grade isolation is the defining characteristic of this 46mm profiled bobbin mount, PR464025-45, rated at 45 Shore A, the grade within the profiled bobbin family that delivers the greatest deflection under load and the most effective attenuation of lower-frequency vibration. With a maximum load rating of 38 kg per mounting and a height of 25 mm, it is proportioned for lighter and compact installations where sensitive equipment must be decoupled from structure-borne vibration rather than restrained against shock. The outer diameter is 46 mm (D1), with a secondary diameter of 40 mm (D2), and the mount accepts M10x28 male thread at one end and a standard M10 female thread at the other, giving a male-female configuration that integrates cleanly into existing machine frames or fabricated brackets. Rubber-to-metal bonded construction gives the mount its load-bearing integrity while the 45 Shore A rubber compound provides the compliance that lighter and sensitive equipment demands. The soft durometer means the rubber deflects more freely under the applied load, sustaining the isolation efficiency that higher-Shore grades trade away in favour of stiffness. The mount may be loaded in shear, compression or a combination of both, widening the range of installation geometries it can accommodate. For applications where oil-resistant or high-temperature rubber compounds are required, custom variants are available on request, as are stainless steel metal parts. PR464025-45 is well suited to instrument supports, light-duty air-conditioning units, small generator sets, and similarly compact or sensitive machinery where vibration isolation is the primary engineering objective.

A. The PR464025-45 is rated to a maximum load of 38 kg per mounting.
A. The outer diameter (D1) is 46 mm, the secondary diameter (D2) is 40 mm, and the height (H) is 25 mm. The mount has an M10x28 male thread at one end (d1) and a standard M10 female thread at the other (d2).
A. At 45 Shore A, this is the softest grade in the profiled bobbin range. Softer rubber deflects more under load, delivering greater vibration isolation — particularly at lower frequencies. It is the appropriate choice for lighter or sensitive equipment where isolation efficiency takes priority over maximum load capacity or restraint. Firmer 60 Shore A and 70 Shore A variants of the same geometry are available where higher loads or less movement are required.
A. The mount may be used in shear, compression, or a combination of both, accommodating a range of installation orientations.
A. Typical applications include instrument supports, air-conditioning units, small generator sets, exhaust mountings, diesel engines, and other light-duty or sensitive industrial machinery. Industries served by this bobbin family include power generation, agriculture, construction and off-highway, marine, automotive, and railway.
A. Yes — oil-resistant and high-temperature rubber compounds, stainless steel metal parts, and custom sizes are available on request.
A. Yes. The same 46 mm × 25 mm geometry is available in 60 Shore A (PR464025-60) and 70 Shore A (PR464025-70). Larger profiled bobbins include PR403528, PR757040, PR1009555, PR1009575, and the compact PR262222.
A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product tech specs or datasheet where available.
