Other sensor bearing units
The SKF assortment of sensor bearing units is
not limited to motor and roller encoder units.
SKF has developed several solutions addressing
specific applications, where sensor integration
is a major added value. For additional information
about these application specific sensor
bearing units, contact the SKF application
engineering service.
Steering encoder units
SKF steering encoder units († fig. 17) are
plug-and-play steering input devices for
steer-by-wire systems. They combine reliable
encoder technology with the simplicity of plugand-play
component packaging.
Designs and variants
SKF steering encoder units are based on
well-proven SKF technologies. They have been
designed from the inside out, starting with
bearing encoder technology, to precisely
moni tor steering. From there, a friction torque
device, mechanical interface for mounting and
a shaft to connect the steering wheel are added
to create a complete unit. The friction torque
device provides feedback to the operator by
providing adequate resistance in the steering
wheel.
The units contain a sealed SKF Explorer
deep groove ball bearing to provide long service
life and reliable performance. They do not
require any adjustment or relubrication during
their expected service life and are considered
maintenance-free. They reliably fulfil the
demands of industrial and off-highway vehicle
steer-by-wire systems.
SKF steering encoder units are supplied
ready to mount. Connection to a steer-by-wire
system is achieved by plugs. Available steering
encoder units are listed in table 4. For additional
information about SKF steering
encoder units, contact the SKF application
engineering service.
