Many of these new ideas and customer inputs are
developed from working directly with new customers on
custom designed actuators. Our engineering and sales
team welcomes your input and looks forward to helping
develop products meeting your specific needs. Parker
Pneumatic Division is the industry leader in actuator
technology. We have invested in the engineering and
analytical tools to fully understand the capabilities of
our product offerings. We have the team in place and
the analysis and technical capabilities to evaluate your
special requirements and to work with your engineers
to establish an optimum solution.
Rack-and-pinion actuators offer the opportunity for
the customer to define and integrate specific features
or strengths into the actuator housings. If required,
special actuator housings can be fabricated from a
machined block or a weldment versus the standard cast
housing. This special housing can be designed with
special dimensional features and strength capabilities
to integrate directly into the customer’s structure. The
actuator assembly thus becomes a drop-in device with
precision-machined features defined by the customer,
built-in bearing capability, and other critical features
in addition to supplying rotary power and positioning.
These values are incorporated into one low-cost
package the customer can buy, without doubling up
on the expense of building similar features into his
apparatus.
