KERK® LEADSCREWS are available in standard diameters from 1/8" (3.2mm) to 15/16" (23mm), with standard leads from .012" to almost 4" (0.30mm to 92mm) including metric and left hand threads. Custom sizes and leads can be special ordered. Most stock screws are manufactured from 303 stainless steel and are produced with Haydon Kerk's exclusive precision rolling process. Other materials are available on special order.

Positional bi-directional repeatability (with the Kerk anti-backlash nut) is within 50 micro-inches (1.25 micron) and standard lead accuracy is better than 0.0006 in./in. (mm/mm). Lead accuracies are available to .0001 in./in. (mm/mm). Please contact Haydon Kerk Motion Solutions in-house technical experts for more details or special requests.

87000 Series, Size 34... our largest, most powerful linear actuator is also available with a captive, non-captive, and external linear shaft. Despite its large size and strength, this motor incorporates the same precision, high performance and durable patented designs featured in our entire hybrid product line. The 87000 series delivers forces up to 500 lbs. (2224 N) in a compact, 3.4-in (87 mm) square package. The 87000 Series is available in a wide variety of resolutions - from 0.0005-in (.0127 mm) per step to 0.005-in (.127 mm) per step. Speeds exceed 3.0-in (7.62 cm) per second.

In addition to our standard configurations, HaydonKerk Motion Solutions™ can custom build this powerful motor to meet your specific motion requirements. The in-house design and engineering team is available to assist you with a solution to fit your needs and your budget.

The Haydon™ line of dual motion actuators provides independent linear and rotary motion from a compact package. The actuators are based on unique, patent pending designs and incorporate Haydon Kerk Motion Solutions proven motor technology. These units simplify product development by replacing what would otherwise be far more bulky and complex mechanisms. Another feature of this design is to provide an electric motor in which linear and rotary motions are controllable independently of one another.

A limitless number of operating parameters are offered allowing each device to be custom manufactured according to customer specific application requirements. For a rotary/linear motor, it is desirable that the linear and rotary motions be controllable independently of one another. These devices can be run using a standard two axis stepper motor driver. Performance can be enhanced using chopper and/or microstepping drives.

Haydon Kerk Motion Solutions offers a unique line of hybrid linear actuators that open new avenues for equipment designers who require high performance and exceptional endurance in a very small package. The various patent pending designs use a proprietary manufacturing process, which incorporates engineering thermoplastics in the rotor drive nut and a stainless steel acme lead screw. This allows the motor to be much quieter, more efficient and more durable than the v-thread and bronze nut configuration commonly used in other actuators. Motor life is improved more than 10 times over the traditional bronze nut style – and it requires no maintenance and does not affect the cost. An additional feature is the bearing pre-load adjustment which, unlike other designs, does not protrude from the motor configuration commonly used in other actuators.

The Haydon™ brand of hybrid linear actuators come in six sizes, from 21 mm square to 87 mm square. Each size has three designs available – captive, non-captive and an external linear version. There are over twenty different travels per step available, from .00006 inch (.001524 mm) to .005 inch (.127 mm). Micro stepping can be used for even finer resolution.

These linear actuators are ideal for applications requiring a combination of precise positioning, rapid motion and long life. Typical applications include X-Y tables, medical equipment, semiconductor handling, telecommunications equipment, valve control, and numerous other uses.

Hyadon Kerk's rotary motors are built to provide exceptionally high torque to size ratios. By utilizing a patented enlarged rotor with low inductance coils, the motors provide superior torque and continuous, reliable high performance. At rated voltage, the 46 mm motor produces 16 oz.-in. of holding torque, the 36 mm motor produces 4.5 oz.-in., the 26 mm motor produces 1.8 oz.-in. and the 20 mm motor produces 0.65 oz.-in. Optional rare earth magnets may be specified for even higher torque. Bronze sleeve bearings are standard, ball bearings are also available.

Haydon Kerk Motion Solutions has patented technology and the facilities to produce these motors in high volume. We provide rapid turn-around for prototypes and production orders. Custom designs and special engineering requirements such as special shaft diameters, lengths and mounting flanges are welcome. Some typical applications for Haydon rotary motors include medical equipment, bar code scanning devices, printing equipment, laboratory instrumentation and other high torque, small space mechanisms.
