LF Series Base Element with Hardware Timken 68514446740

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 Notes For Hytrel, dynamic torsional stiffness values are non-linear with respect to torque. Value given is for 100% of nominal torque.

Axial Misalignment (End Float) +0.12 / -0.08 in 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
