Mackay M140350 U-Flex Isolator, 200 kg Static Load, Duro 50
Available
The Mackay U-Flex isolator is a general purpose isolator that offers excellent protection against vibration and shock across a wide range of applications, including electronic apparatus, vibratory feeders, general machinery and equipment in packing cases during transit (manufacturer-stated).
Two sizes are listed, both Duro 50: the M140350 (200 kg static load, 7.5 mm deflection, 1.0 kg) and the M140450 (50 kg static load, 8 mm deflection, 0.2 kg). Mackay says the rubber is used in shear in directions X and Y and in compression in direction Z (manufacturer-stated).
Where this product is used
- Electronic apparatus and vibratory feeders (manufacturer-stated).
- General machinery, and equipment in packing cases during transit (manufacturer-stated).
- Applications where movement needs limiting in one direction (manufacturer-stated).
Features
- Most flexible in directions X and Y, where the rubber is used in shear (manufacturer-stated)
- Greater stiffness in direction Z, where the rubber is used in compression (manufacturer-stated)
- Useful where limitation of movement is required in one direction (manufacturer-stated)
- Other rubber hardnesses available on indent order only, subject to a minimum order quantity (manufacturer-stated)

Selecting the right option
Choose by static load: M140450 is listed at 50 kg and M140350 at 200 kg. Think about which direction the movement will be in: Mackay says the U-Flex is softest in X and Y and stiffer in Z, so fit it to put the limit on movement where you need it. Mackay lists other hardnesses on indent order only, with a minimum order quantity (manufacturer-stated). Mackay prints all properties as nominal and asks you to contact them for technical advice.
