Product Number: 5040MM28-45
Sensitive equipment and lower-frequency vibration sources demand a mount that prioritises isolation over restraint, and the 50x40mm Male-Male Bobbin Mount in 45 Shore A rubber (SKU 5040MM28-45) is engineered precisely for that role. With a maximum load rating of 49.0 kg and a deflection of 3.5 mm, this soft-grade mount allows the greatest movement of the available Shore grades in this geometry, enabling it to absorb lower-frequency vibration inputs effectively before they reach the supported structure or instrument. Rubber-to-metal bonded construction provides reliable performance across shear, compression, or a combination of both loading directions. The M10 x 28 mm threaded stud configuration at both ends simplifies installation into existing fabrications or brackets, and the 45 Shore A rubber compound delivers the characteristic compliance that protects instruments, lighter industrial machinery, and compact equipment from damaging vibration and shock. At the softer end of the hardness range, this grade is well suited to air-conditioning units, instruments, and lighter generator sets where vibration isolation takes priority. The family also finds application in agricultural machinery, marine installations, and railway and mass transit equipment. For environments demanding greater resistance to oils or elevated temperatures, stainless steel hardware and specialist rubber compounds are available on request. For heavier loading or where less deflection is required, this mount is available in firmer grades and alternative sizes: 60 Shore A (5040MM28-60) and 70 Shore A (5040MM28-70) share the same 50x40mm body, while further geometry options include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44.

A. This mount has a maximum load rating of 49.0 kg and a deflection of 3.5 mm, reflecting its 45 Shore A soft-grade rubber compound.
A. At 45 Shore A, this is the softest grade available in the 50x40mm bobbin range. Softer grades allow greater deflection under load and deliver better vibration isolation, particularly at lower frequencies, making this grade the preferred choice where isolation matters more than restraint.
A. The 45 Shore A grade is well matched to lighter or sensitive applications including instruments, air-conditioning units, and compact generator sets, as well as marine, agricultural, and railway and mass transit equipment where lower-frequency isolation is the priority.
A. This mount may be loaded in shear, compression, or a combination of both, offering flexibility across a range of installation orientations.
A. The mount has male M10 x 28 mm threaded studs at both ends, in a male-male bobbin configuration.
A. Yes. The same 50x40mm geometry is offered in 60 Shore A (5040MM28-60) and 70 Shore A (5040MM28-70) for applications requiring higher load capacity or reduced deflection.
A. Stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for applications where the standard specification is unsuitable.
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).
