Product Snapshot

|
Application Note:
The SS Series uses a steel base in its design for exceptional rigidity.
|
Product Description
|
By utilizing steel, the new SS Series is an extremely small
and lightweight unit with specifications comparable to those of larger IAI
actuators. This lightweight design allows the SS Series Actuator to
handle a wider variety of applications including those with limiting space
constraints.
Add either the X-SEL motion controller or the
E-Con positioner, and you can use Solid Series actuators for both single-
and multi-axis positioning.

Series Features
|
The SS Series has the most rigidity for the smallest amount
of width out of any IAI actuator. This compact design has aided in
the integration of the SS into systems where space constraints are an
issue, and the following features are a necessity: 
- Brushless AC Servo Motors with incremental or absolute optical
encoders.
- A variety of standard ballscrew leads and ballscrew diameters.
- Smaller width than the larger IS Series actuators.
- An extremely strong steel/aluminum composite frame with a high
degree of torsional rigidity. This rigidity is especially important in
multi-axis, Cartesian Coordinate positioning systems.
- A high strength-to-weight ratio that lets you use SS Series
actuators in gantry-style systems.
- A high ratio of stroke length to overall length is made possible
through the use of a small but powerful AC Servo Motor and also because
the ballscrew and motor shaft are one. No coupling is used in SS
Series actuators.
- The elimination of the coupling used to connect the ballscrew with
the motor because, unlike conventional designs, the ballscrew is the
motor shaft.
- A protective stainless sheet as a standard feature to help restrict
the migration of particles generated from within the actuator.
- Designed for high velocity and high payload with excellent
positioning repeatability.
Options include:
- Magnetic brake
- Limit switches
- Creeping sensors
- Sine-wave Drive Option for smoother control
- AQ Seal Long-Term Lubrication

Controller Features
|
The X-SEL Controller is used to drive the SS actuators.

The E-Con positioner may also be used for single-axis applications
requiring only simple point-to-point motion.

Actuator Specifications
|
Moment Load and Overhang
The SS Series actuator is rated at 10,000 Km of lifespan
using direct recirculating ball bearings running in a hardened carbon
steel ground track. This construction used in conjunction with an
integrated motor/ballscrew makes the SS Series one of the most functional
Cartesian actuators in the marketplace.
