The trend in
industry to process more material faster and more efficiently calls for a
high-torque, high-misalignment, low-inertia servo coupling, with minimal compromise
to torsional stiffness. Stainless-steel bellows couplings have the highest
torsional stiffness of commercially available flexible couplings, making them
the best choice for aggressive servo-driven applications. But in cases where
the two shafts to be connected are mounted to different bearing surfaces, it
can be difficult to maintain the precise alignment tolerances normally
special, high-stiffness bellows and new, high-strength connection method, R+W's
handles an average of 2.6 times the traditional torque rating at a given
outside diameter, and an average of 2.9 times more lateral misalignment,
opening up the benefits of precision bellows couplings to a whole new segment
of machine design and servo motion control.
diameters ranging from 15 to 60 mm and torque ratings from 20 to 1,000Nm, the
BKZ range is available in four sizes, with a variety of materials, finishes and
the optional self-opening clamp system.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
