Cardan Shafts
SWC-BH Telescopic Welded Cardan Shaft
SWC-BH telescopic welded cardan shaft with rated and fatigue torque, operating angle, length compensation, dimensions and assembly drawing.
Product Overview
The SWC-BH Telescopic Welded Cardan Shaft is a universal-joint shaft configuration for drive lines that require an operating angle and length compensation. The model table brings together swing diameter, rated torque, fatigue torque, operating angle, telescopic movement, minimum length, flange and shaft dimensions, inertia and mass. A complete inquiry should state the installed length and surrounding clearance as well as speed, torque, angle and flange interface, because the shaft geometry and duty are interdependent. The published data is intended for preliminary comparison; final phasing, connection dimensions, material, balancing and operating suitability require technical confirmation.
Key Features
