What Are Cylindrical Bobbin Mounts?
Cylindrical anti-vibration mounts, widely known as bobbin mounts or cylindrical buffers, are the most versatile isolator in the anti-vibration range. A moulded natural rubber body is chemically bonded between two steel end fittings, so the mount carries load in compression, shear or a combination of both depending on how it is installed. That flexibility is why the same part appears under exhaust brackets, control panels, fan housings and small pump skids.
ABAW supplies the full BC series across five thread configurations. Type A has a male stud at both ends, Type B is male at one end and female at the other, Type C is female at both ends, Type D is a single male stud, and Type E is a single female boss. Choosing the right configuration is usually decided by what is already tapped or drilled on the equipment and its mounting frame.
Hardness runs from 30 Shore A for soft isolation of light equipment through to 70 Shore A where the mount must resist higher static load with minimal settlement. Because deflection changes with hardness, the same physical size can serve very different load cases: a BC 100 x 90 carries 285kg at 30 Shore A and 540kg at 50 Shore A.
Stock is held at our Sharjah warehouse for delivery across Dubai, Abu Dhabi and the northern emirates, with regular export shipments to Saudi Arabia, Oman, Qatar, Kuwait, Bahrain and African markets. Bespoke sizes, thread forms and rubber compounds can be produced to order.

Frequently Asked Questions
What is the difference between Type A, B, C, D and E cylindrical mounts?
The letter refers only to the thread arrangement at each end. Type A has a male stud on both faces, Type B has a male stud on one face and a tapped female boss on the other, Type C is female on both faces, Type D has a single male stud with a plain opposite face, and Type E has a single female boss. The rubber body and load ratings are identical across the types for a given size and hardness, so you select the configuration that matches the tapped holes or clearance holes already present on your equipment and its frame.
How do I choose the right Shore hardness for a bobbin mount?
Divide the total supported weight by the number of mounts, then pick the hardness whose maximum load rating sits comfortably above that figure, typically loading the mount to between 50 and 80 percent of its rating. A softer 30 Shore A mount gives more deflection and therefore better isolation, but settles further under load. A harder 60 or 70 Shore A mount holds the equipment more rigidly and suits higher loads or applications where alignment matters. If you are unsure, send us the equipment weight, the number of mounting points and the running speed and we will recommend a size.
What load can a cylindrical rubber mount carry?
Across the BC range the maximum static compressive load runs from 6kg on a BC 20 at 30 Shore A up to 540kg on a BC 100 x 90 at 50 Shore A. The full load and deflection figures for every size and hardness combination are listed in the Specifications tab. These are compressive values, so if the mount will carry load in shear or in a combined orientation, the working capacity is lower and should be confirmed with our technical team.
Can ABAW supply cylindrical mounts in sizes not shown in the chart?
Yes. Non-standard diameters, heights, thread forms and rubber compounds are produced to order. Common requests include neoprene or nitrile bodies for oil and fuel exposure, stainless steel fittings for marine and coastal use, and imperial thread forms for legacy equipment. Tooling lead times apply for entirely new sizes, so share your drawing or a sample and we will confirm feasibility and lead time.
Do you deliver anti-vibration mounts outside the UAE?
Yes. Stock is dispatched from our Sharjah warehouse to all seven emirates, and we ship regularly to Saudi Arabia, Oman, Qatar, Kuwait, Bahrain and Egypt, as well as to African markets including Nigeria, Kenya, South Africa, Ghana, Tanzania and Ethiopia. Bulk and container quantities receive wholesale export pricing.
