1 Miniature MCM, MCM Supports small conveyors and test equipment in a wide range of applications. Compact, lightweight design saves space and delivers high performance. Patent Pending

2 Lightweight, space-saving structure made possible through compact design. These all-in-one s are easy to use and provide high accuracy and rigidity. s are used in a variety of applications, including production, inspection, packaging and conveyance systems. lready recognized in the industry for improving efficiency and reducing labor, s have been increasingly in demand to meet a growing range of needs. NSK has been developing a wide range of s, making full use of its world-class technologies in ball screws and linear guides. To meet demand for smaller, lighter s, NSK developed the MCM and MCM, a series of compact s that realizes unprecedented lightweight and space-saving features. In addition, these s feature NSK s state-of-the art technologies, such as a long life, maintenance-free NSK K lubrication unit, an all-in-one structure for easy use, and high accuracy and rigidity, earning the product line a reputation for outstanding reliability. These small and lightweight s are consequently well equipped to meet specific needs.

Lightweight, compact design Integration of components minimizes cross-sectional dimensions, while reducing weight by one-half compared to existing combination units (single-axis tables). This compact design meets the demand for lighter weight and saving more space.. ll-in-one structure The all-in-one structure, integrating ball screw and linear guide into a single unit, significantly reduces workload for design and installation.. Long-term, maintenance-free operation The NSK K lubrication unit is incorporated into the guide and ball screw parts for the MCM and MCM. The use of the NSK K lubrication unit maintains smooth lubrication performance for long periods in mechanical environments where lubrication is difficult to apply, such as machinery and equipment for food processing and medical applications requiring a highly clean environment, thus enabling maintenance-free operation over an extended period of time.. vailable in small and large ball screw leads range of standard sizes is available between millimeter small lead to millimeter large lead.. nticorrosion feature Special surface treatment is provided as a standard feature to prevent corrosion under various operating conditions.. High accuracy and rigidity The concave main base, although lightweight, resists bending and can be used as cantilever beams. The structure, composed of several rolling elements, reduces friction and provides higher positioning accuracy. Reference number coding The reference number is composed of the main basic specifications. Example: MC M H K Series (M: MCM type) Nominal size (rail width, unit: mm) Stroke (unit: mm) K: Single slider D: Double slider (made to order) Ball screw lead (mm) ccuracy grade: H: high grade P: precision grade

3 How to Select s MCM, MCM rigidity Rail material rigidity The MCM and MCM rail features a special concave shape with a small space to maintain high resistance to deflection and distortion. The geometrical moment of inertia of rail area in each direction is shown in Fig.. Permissible speed The relationship in permissible speed between rated speed and stroke is shown as follows: Fig. Permissible speed Fig. Rail material rigidity e ly Center of gravity lx Rated speed [mm/sec] Ball screw lead (mm) MCM (L) MCM (L) MCM (L) MCM (L) MCM (L) MCM (L) Rail material rigidity Stroke [mm] Geometrical moment of inertia [mm ] Center of gravity [mm] lx ly e MCM...

When packing grease into the unit, apply it directly to the rail groove or ball screw groove or use a grease gun or similar tool to pack it into the grease inlet hole located on the side of end cap (as shown above). Generally, the applied area must be filled with grease to the point where a small amount of supplied grease is discharged around the area surrounding the ball slide.
