Zero backlash. Jam-proof design.
Hi-tech Engineering linear drives have zero play when the shaft is rotated even during reversal. The threadless shaft won't clog or jam. If the system is somehow overloaded, the shaft simply slips instead of churning and grinding.
Free movement lever
The Free Movement Lever on a Hi-tech drive lets you slide the drive anywhere along the shaft without need to turn on the motor. This dramatically reduces wear and tear and the system and eliminates the need to jog the drive into place by turning the motor on and off.
