Ball Small Jack

Outline

Extremely compact, lightweight, and easy-to-use ball screw jacks, delivering high performance comparable to standard ball screw jacks.

Basic capacity: 4 kN
Achieves the lightest possible weight while maintaining sufficient strength.
The housing is compact and designed for installation from either the upper or lower surface of your device.
High efficiency and high-speed operation are realized through rolling friction.
A version with an anti-rotation mechanism is available to prevent the screw shaft from co-rotating.
Wide-ranging options are offered, including dustproof bellows to protect the screw shaft, limit switch for control, and RC encoder.
This jack does not have a self-locking function, so a brake must be installed for safe use.
