Kinematic configurations of Haydon stepper linear actuators

Haydon linear actuators are engineered in three distinct mechanical configurations to match machine integration requirements.

Captive units feature an internal anti-rotation spline shaft that prevents the lead screw from turning, thereby converting stepper rotor rotation directly into linear thrust without requiring external guide rails.

Non-captive actuators allow the threaded lead screw to extend through the center of the motor rotor, making them optimal for setups where the external mechanism provides anti-rotation guidance.

External linear versions utilize a rotating screw shaft coupled to the rotor that drives an external Kerkite polymer nut along the stroke.

Thread geometry and Kerkite anti-backlash nut engineering

Kerk precision lead screw assemblies utilize a modified Acme thread form engineered with an optimized contact angle, delivering high axial load ratings paired with low frictional drag.

Rolled from 303 stainless steel with fine surface finishes, the screws are coated with proprietary dry Kerkote TFE fluoropolymer, eliminating the requirement for wet oil lubrication.

Anti-backlash nuts in the BFX, KSS, ZBX and WDG series incorporate an internal spring-loaded mechanism that automatically compensates for axial wear. This eliminates lost motion during directional reversals, damps mechanical vibration and ensures repeatable positioning throughout long service lives.

Integration of RGS and WGS motorized linear rail modules

Haydon Kerk motorized guide systems such as the RGS and wide-body WGS series deliver complete pre-aligned motion platforms built around rigid aluminum alloy profile bases.

The moving carriage glides along precision polished guide shafts using Kerkite polymer bushings, ensuring silent operation and zero ongoing lubrication maintenance.

Integrated longitudinal T-slots in the extrusion profile simplify the installation of home limit sensors and mechanical stops. When building multi-axis cartesian platforms, RGS modules connect into orthogonal X-Y-Z configurations with high structural rigidity.

Selection of Pittman brushed and brushless DC servomotors

Pittman direct-current motors deliver broad speed and torque envelopes for industrial automation tasks. Brushless BLDC models across the EC033A, EC042B and EC057B/C families are rated for continuous round-the-clock operation with rotor speeds reaching 15,000 rpm.

Equipped with internal Hall sensors, they provide low electromagnetic emissions.

Brushed DC motors in the DC026C through DC054B lines and GM8000/9000 gearmotors feature proprietary Lo-Cog skewed rotor laminations, eliminating reluctance cogging torque at low crawl speeds.

This makes them well-suited for automated fluid dispensing pumps, precision metering and laboratory positioning.

Configuring IDEA Drive digital motion controllers and feedback

Smart digital drive units in the IDEA Drive ABL, CBL and PBL series combine programmable multi-axis trajectory generation and power amplification within a compact footprint.

Internal non-volatile memory stores user motion routines, enabling standalone sequencing triggered by discrete digital inputs without continuous supervisory polling.

For high-precision closed-loop feedback, motors are configured with incremental optical or magnetic encoders from the AE16, E21 and E30 series. Differential line drivers provide strong noise immunity in demanding factory control panels with heavy electrical transients.

Submitting engineering specifications for component matching

To expedite accurate component selection and cross-referencing, provide the full alphanumeric model code from the actuator or motor marking plate (such as 43H4N-2.1-001, BFX-0250, RGS04-200, EC042B-001 or GM9236S021-R1).

If the label is illegible, specify motor frame size, screw lead, carriage stroke length and operating supply voltage.
