LF Series Base Element with Hardware Timken 68514450682

Описание

The heart of the LF Series coupling is the flexible base element. Thiselement allows the customer to make their own shaft hubs from steel barstock or use existing hubs. Ideal for quick prototype testing, retrofit and highvolume applications. Notes Disclaimer Lovejoy: CAD Models are accurate envelope dimensions only. Features such as bore size and keyway are not rendered or are only representative. Contact Lovejoy Technical Support or refer to product catalogs for details. Notes For Hytrel, dynamic torsional stiffness values are non-linear with respect to torque. Value given is for 100% of nominal torque. Specifications Description LF250-ELE-HY-W/HDWR Coupling Size LF250 Coupling Type Torsional Material Hytrel® Bore Type Element w/ Hardware Color Beige Weight 25.13 lb Dimensional Data Thread (Dimension T) M20 Length thru Bore 3.030 in Dimension HD 6.299 in Max. Bore (Dimensions ID1/ID2) - Flanged Hubs 5.000 in Cubic inches 542.44393 in³ Performance Data Normal Temperature Range -60 to 250 ºF Torsional Element Specifications Torsional Element Specifications Elements made of DuPont’s Hytrel® elastomer compound are torsionally much stiffer than natural rubber (20 times stiffer) and were developed for combustion engine / hydraulic pump applications. Hytrel® elements have 20% greater torque capacity as compared to rubber elements. The torsionally stiff Hytrel® element moves the harmful vibration resonance frequency above the operating RPM range. The element design also reduces harmful radial and axial reactionary forces. Features Features Wide range of standard designs and materials
