Mackay M130003 Annular Isolator, 14 x 18 mm, 1.25 kg Load, Green
Available
Mackay annular isolators give large deflections under small loads. Mackay says they protect instruments and apparatus from transmitted vibration and shock as well as vibration from light machines and equipment, and that they replace Hy-Deflection low-frequency isolators (manufacturer-stated).
This listing has four variants in two sizes with a threaded stud on each end: 14 x 18 mm with M4 studs (M130001, 2.5 kg, and M130003, 1.25 kg) and 24 x 30 mm with M8 studs (M130002, 8 kg, and M130004, 3.5 kg). Each is marked Red or Green. Mackay says they are normally fitted to take loads in compression or shear (manufacturer-stated).

Dimensions are in millimetres and the letters follow the catalogue drawing: A width, B length, C stud thread, D height, E stud length. Mackay prints all properties as nominal and asks you to contact them for technical advice. The same 24 x 30 mm body with type 304 stainless steel is listed as M130004SS304 in the stainless annular listing.
Selecting the right option
Choose by load and size: the 14 x 18 mm parts carry 1.25 or 2.5 kg and the 24 x 30 mm parts 3.5 or 8 kg. Work out the share of weight each isolator carries, and avoid loading the rubber in continuous tension. Check the stud thread (M4 or M8) and stud length (8 or 20 mm) against your fixing. Confirm critical loads with Mackay.
