R+W. Since 1990 the German-based designer and manufacturer of precision
couplings for high performance drive systems has strived to offer the best
in standard and custom solutions for the most
demanding applications. In addition to having
readily available zero backlash coupling models
in stock in basic economy configurations, R+W
is also constantly engineering unique flexible
couplings and torque limiters based on
specific customer requirements for extreme
speed, torque, stiffness and more. The units
deployed by R+W include couplings running
at speeds in excess of 150,000 rpm, and
ball-detent clutches holding loads of over
20 million Nm. Beyond coupling engineering
feats, one of the keys to
the success of R+W
continues to be
its adaptability to
customer needs.
Some of the more
popular developments
in recent years include the CH
series of inline and parallel servo motor mounts
for linear actuators, the SCL series of servo-rated
disc pack couplings for higher misalignment,
and the SL series of precision ball-detent torque
limiters, available for quick delivery out of R+W
America in Illinois. Customers also benefit from
USA-based applications engineering offering easy
communication and quick turnaround for special
designs. Whether for micromotors or multi-megawatt mill
drives, R+W has the coupling solutions for almost any situation.
