Ruland jaw couplings for servo motors

Zero-backlash jaw couplings from Ruland have high dampening capabilities, can
accommodate all forms of misalignment, and are highly customizable. They are well-suited
for servo motors that are often used in precise positioning
applications found in semiconductor, solar, medical and robotics.
Zero-backlash jaw couplings are a three-piece design comprised
of two lightweight aluminum hubs and an elastomeric insert
“spider.” The spider is available in
three durometers: 98 Shore A for
the highest torque, 92 Shore A for
a balance of stiffness and
compliance, and 85 Shore A for the
highest dampening capabilities.
Inch, metric, keyed, and keyless
hubs with clamp or set screw
hardware can be combined to fit user
shaft requirements.
