The result: quality, reliability and performance with average savingsof 15-20% over competitive smaller overall size also makes Lifelign Couplings well suited for limited space appli-cations that still require large bores and high torque for Existing ApplicationsHalf for half interchangeability allows you to add capacity and realize the advantages of Lifelign Couplings on your existing appli-cations and designs, as s more, Lifelign s larger hub diameter features more metal over the keyway versus other designs,providing greater reserve strength against hub fractures due to shock or impact loads.

It s very compact, low in rotating mass, and has alower initial cost than flanged types. (See Pages 16 & 17.)Type GC05 Floating ShaftFloating shaft assemblies are used when distance betweenequipment is too great for spacer Couplings . A standard floatingshaft assembly consists of two standard single engagementcouplings and a connecting shaft. A floating shaft can eliminate theneed for additional bearing supports along spanning shafts becausethe shaft is supported by connected equipment through the singleengagement Couplings .

10 (See Page 18.)The Type G20 double engagement, close coupled type has twoflex halves to accommodate both offset and angularmisalignment or a combination of the two, as well as end float. Itis ideal for all horizontal, close coupled applications includingfans, overhead cranes, conveyors, steel and paper millequipment. It is adaptable with limited end float kits for use onelectric motors, generators or any machines fitted with sleeve orstraight roller bearings. (See Page 19.)Type GV20 vertical double engagement coupling is a standardhorizontal double engagement gear coupling modified toaccommodate the sleeve centering assembly. Recommended forinclinations over 10 . (See Pages 24 and 45.)The Type G Large gear coupling is available in all types forcapacities up to 8,185,000 Nm, (72,450,00 lb-in. (See Page42.)Types G20 & GV20 Spacer Couplings for pump and compressor applications simplifyservicing connected equipment.
