We take complexity out of the equation and enable you to develop your technology and ramp up production quickly. The new NSK Electrified Monocarrier linear actuator was designed for high performance and long life, in a small footprint.

This all-in-one actuator includes the optimum combination of the following, each fully tested and pre-assembled:

  • NSK precision ground ball screw
  • NSK linear guide with K1™ lubrication
  • NSK support bearings
  • NSK inline or side wrap motor mount
  • Sanyo Denki Stepper or Servo motor
  • Optional accessories such as covers, sensor kits and sensor rails

With combination plates and gantry brackets available, you can easily combine Monocarriers into any XYZ configuration.

Monocarrier Accessories

Optional accessories to complement your NSK Monocarrier


Sensor Rail and Kits

  • The sensor rails provide simple feedback for actuator location
  • Optional rail for sensor mounting is available
  • Proximity Sensors – Normally open or Normally closed type
  • Photo Sensors – PNP or NPN type

Motor Bracket and Side Wrap Kits

  • Motor bracket – Inline motor mounting option
  • Motor Wrap kit – “lefty” or “righty” orientations available to accommodate  mounting or space constraints

Sanyo Denki Servo or Stepper Motor

  • Servo for higher speeds and torques is available for MCM/MCE 03 and up
  • Stepper is more traditional option with a simpler setup, available for MCM/ MCE 02 and 03 only

Cover Units

  • Protect against larger contaminants with optional cover units
  • Full cover option includes top and side covers (note: prohibits use of sensor rail)
  • Top cover option provides protection as well as use of sensor rail

Combination Plates and Brackets

  • Used when movement in more than one plane is desired, i.e. X-Y-Z combination
  • Combination brackets join together two Monocarriers to allow movement in multiple planes
  • Gantry Plate allows for addition of a support rail for severely cantilevered Y-axis load conditions

Case Study: 3D Printing for Mass Manufacturing

A 3D manufacturer developed a revolutionary technology that significantly speed up the printing process to enable both production flexibility and high-volume capacity.

Technical Challenge

The 3D printing OEM had a small footprint available to design a linear positioner that can support and move the printer’s build platform, while also preventing the large reversing forces induced by the build platform and the liquid resin. High rigidity and low backlash mechanism were also needed to enable exceptionally accurate positioning to produce high precision parts.

Monocarrier linear actuator with dual carriages

NSK Solution

Locally-based NSK Application Engineering recommended the Monocarrier linear actuator with dual carriages to provide a compact sized positioner with high stiffness, load capacity and smooth motion. The Monocarrier also comes standard with NSK’s K1 lubrication seal that allowed the customer to enjoy maintenance-free operations for up to 5 years or 10,000 km of travel.
