NSK: High-Rigidity Type MCH Monocarrier

This new product brings powerful features to the unparalleled Maintenance-free Series Monocarrier, a series which resulted from NSK’s extensive development efforts. Monocarriers are light, compact single axis actuators combining ball screws, linear guides, and supporting bearings.

In addition to simplified design and installation, MCH Monocarriers feature improved rigidity, making them suitable for cantilever beams. Furthermore, the long-term, maintenance-free NSK K1® lubrication units are built-in as a standard feature, preventing oil contamination of the operating environment.

MCH Monocarriers represent an important new addition to the MCM series, providing users with diverse functionality for systems solutions.

• Enhanced rail rigidity:

  While MCM predecessors focused on light weight, MCH Monocarriers provide improved rail rigidity, which is now available for cantilever beams. MCH Monocarriers are three to eight times more rigid than conventional products agains vertical load.

• Long-term, maintenance-free usage:

  The combined use of the NSK K1 with grease maintains long-term operating efficiency in mechanical environments where lubrication is difficult to apply.

• Preventing oil contamination of operating environment:

  Using NSK K1 with minimal grease ensures sufficient lubrication, even in oil-sensitive locations and in mechanical facilities with sever hygienic restrictions.

• Excellent corrosion resistance:

  Low-temperature black chrome treatment on rail and slider as a standard feature prevents corrosion under ordinary storage and usage conditions. Optional low-temperature chrome flouride treatment further improves anti-corrosion properties.

• LED-hall element equipped sensors:

  The incorporation of LED into NSK's compact, original hall element type sensor facilitates performance verification. The adoption of an exclusive sensor rail allows sensors to be freely mounted at any position.

• Simplified design and installation:

  Rail, ball screws, and support bearings are fully integrated into a single unit to dramatically reduce the time and effort required for design and installation. In addition, standard Shell AV2 grease is prepacked for shipment so that MCH Monocarriers are ready to operate after a break-in period.

• Enhanced dust-proof capability:

  Upper seals are mounted as a standard addition to conventional side seals, preventing the entrance of foreign matter from the upper side.

• Compactness:

  Product design fully utilizes internal cross-sectional parts to reduce actuator size while achieving a high level of rigidity for cantilever beam.

• Longer operating life:

  Actuators incorprate NSK's exclusive, world-leading rolling bearing technologies using ball screws and linear guides, which contribute to less wear and longer accuracy and fatigue life.

• Four-directional iso-load:

  Contact angle of guide bearings is set at 45 degrees to provide equivalent support for vertical and lateral loads.

• Double slider:

  Double slider specifications are also available to improve moment load capacity and straightness.
