Myung Shin IRJ Series Rack Jack Self-Driven Rack-and-Pinion Lift Unit (Single Unit)
Myung Shin IRJ Series Rack Jack Self-Driven Rack-and-Pinion Lift Unit (Single Unit)
Rack-and-pinion jack derived from the power base: rotating the drive shaft moves the rack gear linearly, giving fast motor-driven lifting.
Key features
- Rack gear directly engaged with pinion for high-speed linear motion
- Low power loss and high mechanical efficiency
- Simple structure with easy maintenance
- Precise intermediate positioning possible with a low-speed brake motor
- More economical than a screw jack
- Clean room version (IRJC) with plating, bellows and lower cover
