Description

Lim-Tec DMB Series Ball Screw Actuator

High precision motion, the smooth movement, low noise, high speed

Lim-Tec DMB Series Servo Actuators adopt an advanced European servo actuator design concept, combined with imported key components and local precision assembly, ensuring outstanding performance and a leading position in the domestic market.
Equipped with ground or rolled ball screws, the DMB series achieves ±0.02 mm / ±0.05 mm positioning precision depending on configuration with a maximum rated load capacity of up to 100 tons, a maximum speed of 1 m/s, and support 100% continuous duty operation. The servo actuator provides high-performance motion control with precision force control accuracy of 5% and closed-loop control accuracy up to 1%.
Designed for harsh operating environments, the servo actuators provide long-term maintenance-free operation, combining high load capacity, high speed, high precision, smooth motion, and low noise performance. The integrated anti-rotation mechanism ensures accurate positioning control and enhances overall system safety.

Actuator Accessory Options
The DMB series can be equipped with a complete range of accessories and functional options, including:
Protective bellows / dust covers
Anti-backlash mechanism
Safety nut
Ball screw drive system
Limit switches
Overload clutch
Potentiometer feedback
Encoder feedback
Brake system
Manual handwheel
Mounting accessories and customized installation components
