Lovejoy 68514424514 LF Series Cylindrical Hub - Rough Stock Bore

Features:

• Wide range of standard designs and materials
• Application versatility
• Shaft to shaft or flywheel to shaft designs
• Designed to accommodate substantial shock loads, vibration, and misalignment
• Low moment of inertia
• Electrically insulating
• No lubrication, maintenance free
• Unique air-flow cooling design
• Different element stiffness values allow for torsional tuning of applications with diesel engines
• Economic design allows for cost effective solutions for torsional applications
• Proven L-LOC spline-clamping hub virtually eliminates spline shaft profile wear and "fretting"
• Oil, heat, and corrosion resistant elements (Hytrel, Zytel)
• When used with S-bolts, the coupling can accommodate some end float
• S-bolts accommodate applications requiring "blind" assembly

The LF Series coupling is designed with a unique and highly versatile elastomeric element. These can be easily integrated into a variety of coupling configurations to meet several application needs. LF Style elements are available in a variety of materials to match the necessary coupling dampening characteristics for tuning the systems critical speed away from the application operating speed.

The element can be connected axially to a flywheel adapter plate or flanged hub and radially to a cylindrical center hub using the appropriate bolts. Axial bolt styles include either socket head bolts with a special dry adhesive, or S-Style bolts, which are similar to dowel pins (seen picture below). The radial bolts are used to connect the element to the cylindrical hub. This unique design is remarkably simple, highly effective and gives the LF torsional coupling unmatched performance capabilities. The coupling selection should be verified with a Torsional Vibration Analysis (TVA) of the system.
