For more reliability and durability, the guide rods and leadscrew are protected with a strong machined cover and the encoder is mounted internally directly to the leadscrew rather than being exposed to shock and contamination when mounted in the rear of the motor.

All NB4 series linear stages are machined from 6061 aluminum alloy to provide a light yet stiff and stable stage.

The drive system utilizes a stainless steel ACME leadscrew with internally lubricated plastic drive nut. The drive nut offers zero backlash operation that automatically adjusts for wear to insure zero backlash for the life of the stage.

The use linear guide rods provide a smooth motion. Since the carriage is supported over the entire travel of the stage, a good cantilevered load capacity can be achieved.

Separate connectors for motor power and limit/encoder signals are provided for ease of operation. Integrated limit switches and a high torque size 17 stepper motor are supplied as standard items.
