Force, distance, and speed
Required force / load Force unit N kgf lbf Load type Dynamic moving load Static holding load Peak/shock load Unknown
Travel distance / stroke Stroke unit mm in Move time
Move time unit seconds milliseconds Required acceleration Unknown / not specified Low, gradual ramp Medium High, aggressive move profile Motion direction Bidirectional positioning Extend mostly Retract mostly Frequent reversing / oscillating
Enter stroke and move time to calculate required linear speed.
Mounting, load support, and duty cycle
Orientation Horizontal Vertical, lifting load Vertical, pushing downward Angled / mixed orientation Load support Externally guided load Actuator/screw supports load directly Unknown Screw loading mode Mostly tension Mostly compression Both tension and compression Unknown
Moves per minute Hours per day Days per week
Required service life Unknown Prototype / proof of concept Standard equipment life High cycle production use Critical long-life application Power-off load holding required? No Yes Unknown
Side load / radial load may be present Long unsupported screw length Shock load or impact may occur Very tight package space
Enter moves per minute, hours per day, and days per week to estimate weekly cycle count.
Positioning, environment, and electrical constraints
Required repeatability Unknown Loose, > ±0.1 mm Moderate, ±0.05 to ±0.1 mm Tight, ±0.01 to ±0.05 mm Very tight, < ±0.01 mm Backlash sensitivity Low Medium High Unknown Feedback required? No feedback required Encoder preferred/required Closed-loop positioning required Unknown
Available voltage Unknown 12 VDC 24 VDC 48 VDC Other Driver / controller Unknown / not selected Existing driver must be used Open to recommended driver Integrated driver preferred Ambient temperature Standard room / machine environment Below -20°C Above 55°C Wide temperature swing Unknown
Contamination / particles are a concern Moisture, dust, or ingress exposure Noise or vibration-sensitive application Coating, sealing, or special material may be needed
