High Torque Overload Safety Coupling
Made to protect gearboxes and driveline
equipment from failure due to torque
overload, the new ST1 torque limiter
from R+W offers versatility in a compact
design. Its modularity allows for a
complete breakaway at adjustable
torque levels from 737 to 118,000 lbft,
across four body sizes, and up to
306,000 lb-ft for special applications.
The ST1 is the base model for standard
specifications, available with straightkeyed
bore or frictional clamping hub.
These torque limiters can be mounted
inline with universal drive shafts, or
mounted to sprockets, pulleys, gears
and sheaves. Many other flexible coupling
types are also available for customization.
Standard release torque
values depend on the diameter and
number of safety elements, allowing for
a continuous adjustment range and
easy retrofit for torque increases. Fine
torque adjustment is straightforward as
well, with a marked scale on each individual
element. The key advantage of
the ST series, according to the company,
is fast and simple re-engagement:
after overload and disengagement the
operator needs only to snap the individual
plungers back into engagement.
There are no shear pins, hydraulic fittings
or other spare parts to purchase
and replace. Equipment is up and running
in the minimum possible time.
The ST1 is also available with custom
flanges, torque settings, integral brake
discs, or other types of project-specific
