Wire Rope Isolators – WRI-AXX
Wire rope isolators are typically used in aerospace, defense, industrial, and marine applications to reduce the transmission of vibration and noise, protect sensitive equipment from shock and impacts, and improve overall performance and longevity of machinery.
WRI – A02
Product Characteristics
Each wire rope isolator (WRI) has six alternative configurations with regard to fixture holes (ref. table to the left). When ordering, make your choice and add the required hole configuration code to the type number. First letter is for upper bar and the second letter is for the bottom.
WRI-configurations we produce: II, IY, YY, IM, YM and MM.
