Mackay Anti-vibration mount, M12, load 475

Mackay BRB flange isolator is an anti-vibration mount that works the rubber in shear and compression. Its tall profile gives large deflections, low natural frequencies and excellent vibration isolation, and the range suits applications where isolation in the 85-95% range is a priority. This page covers the Mackay BRB Flange Isolator - Xlarge, available in 2 thread size (mm) options: M12, M16.

This xlarge size has 8 variants, rated from 200 to 475kg, in Duro hardness 40 to 70. Each has a flange base 170mm long with two mounting holes of 12.5mm diameter.

Where this product is used

• Isolating mobile rotating machines that are exposed to axial and radial shocks, dripping, diesel or oil, or the weather
• Mounting machinery where a high level of vibration isolation is required

Features

• Top metal hood protects the rubber from ozone, UV rays, diesel and oils
• Metal parts have an anticorrosive treatment suitable for outdoor use
• Interlocking metal component gives fail-safe protection in mobile applications by limiting upward vertical movement under shock
• Base is engraved with the type and hardness so the mount can be identified later
• Cross stamped on the hood adds rigidity in mobile applications and helps oils and liquids drain off

Key specifications

Choosing the right option

Choose the part by load first, then by hardness: each part number has its own load rating and Duro, so work out the share of machine weight each mount carries and pick the rating that matches. Then check the base against your supporting steelwork: hole diameter 12.5mm, hole spacing 136 to 150mm and overall length 170mm. The other BRB sizes are linked below if your load falls outside 200 to 475kg.
