The SMC MSQA10R is a high-precision rotary table in SMC’s MSQ series, developed for pneumatic indexing, turning, and positioning tasks that require better rotational accuracy than a standard basic-type rotary table. In SMC’s official product structure, MSQA identifies the high precision type, while the suffix R identifies the internal shock absorber type. The MSQ family is built around an integrated concept in which the table and rotary actuator are combined into one compact unit, and SMC also highlights the series for its compact and lightweight design, high durability and high precision, and improved workability through the layout of the end port and angle adjustment mechanism on the same side.
For machine builders, this integrated structure matters. A rotary table that already combines the output table and the actuator reduces the need for extra couplings, custom brackets, and alignment work between separate rotary elements. That usually improves repeatability, shortens assembly time, and makes the machine layout cleaner. In the case of the MSQA10R, the focus is not only on compact rotary motion, but on more accurate and more durable rotary positioning, which is why it is a practical choice for precision-oriented automation modules, inspection fixtures, transfer units, and small indexing systems. SMC’s catalog also shows that the series is available with three mounting methods, which adds flexibility at the machine design stage.

The most important commercial point in this table is the weight. For size 10, the official SMC weight table lists the high precision type with internal shock absorber at 539 g, excluding the weight of any auto switch. That is the figure that should be used when preparing quotations, technical summaries, or listing data for the exact MSQA10R model.
What Makes MSQA10R Different
The difference between MSQA and MSQB is important. SMC explicitly separates the basic type/MSQB and the high precision type/MSQA in the official catalog. This means the MSQA10R is not just another compact pneumatic turntable with a different suffix. It belongs to the precision-focused branch of the series. The catalog’s displacement reference section also compares MSQA and MSQB and indicates lower displacement values for the high-precision side in the published reference presentation. In addition, SMC’s newer product page emphasizes high durability and high precision by means of a large rolling bearing, which reinforces the engineering intent of the MSQA configuration.
That distinction is commercially useful. In many applications, a standard rotary table is enough to rotate a part from one position to another. However, when the machine requires a tighter presentation of the workpiece, more stable rotary end behavior, or more dependable table accuracy under load, the precision type becomes the safer selection. That is where the MSQA10R fits best. It is better understood as a precision-oriented compact rotary table rather than as a general-purpose rotary actuator. This is a technical inference based on SMC’s official differentiation between the MSQA high-precision configuration and the MSQB basic configuration, combined with the published displacement and feature presentation.
Internal Shock Absorber Advantage
The R suffix is also significant. In SMC’s official model structure and CAD entry, R denotes the internal shock absorber type. Compared with a simple adjustment-bolt stop, an internal shock absorber is intended to reduce end-of-stroke impact and support smoother stopping performance. That matters in applications with repeated cycling, light-to-moderate inertia, and requirements for more controlled deceleration at the rotation end. It can help reduce mechanical shock transferred into the table, fixture, and mounted component, which in turn may support better service life and more stable machine behavior over time.
The MSQ documentation also shows that the rotary table supports an angle adjustment range of 0 to 190° with a maximum rotation of 190°. That gives the designer flexibility to set the actual rotation endpoint for the application rather than being locked to one fixed motion. For a machine builder, this is valuable because not every fixture needs exactly 90° or 180° motion. Some systems require a custom presentation angle for inspection cameras, pick-and-place heads, assembly tools, or transfer positions. A rotary table that supports adjustable end positioning is usually easier to integrate into real automation than one with only a fixed stroke.
Installation and Integration Value
Another practical strength of the MSQA10R is installation efficiency. SMC highlights the MSQ family as compact and lightweight, and also notes improved workability by arranging the end port and angle adjustment mechanism on the same face. This matters during machine assembly and service because it simplifies access. In compact automation layouts, poor access to fittings and adjustment points often creates unnecessary labor during assembly, commissioning, and maintenance. By grouping these functions more logically, the series becomes easier to handle in tight spaces.
SMC also states that the MSQ series can be mounted in three ways, and that the mounting dimensions remain compatible with the existing MSQ family. For OEMs and integrators, this makes the MSQA10R easier to adapt to different machine frames, brackets, or replacement projects. In many real-world systems, flexibility at the interface level is just as important as the actuator specification itself, because it reduces redesign effort when the product is introduced into an existing platform.
From the pneumatic side, the MSQA10R uses air without lubrication, has a maximum operating pressure of 0.6 MPa in the internal-shock-absorber configuration, and uses M5 × 0.8 ports for both end and side port arrangements at size 10. The Ø15 mm bore size places it in the compact precision class rather than in the heavy-duty rotary table category. That means it is best suited to compact automation work where controlled positioning and accurate table behavior are more important than large torque capacity.
Product Weight and Commercial Use
For e-commerce listings, quotations, and engineering documentation, the product weight is one of the most useful pieces of factual data, because it affects packing estimates, machine moving mass calculations, and mechanical support design. For MSQA10R, the correct official figure is approximately 539 g, excluding auto switch weight. That number comes directly from SMC’s published weight table for high precision type / with internal shock absorber / size 10. This is the value that should be carried into technical descriptions and product data sheets when the exact model is being identified.
At roughly half a kilogram, the MSQA10R occupies a useful middle ground: it is compact enough for small automated modules, yet substantial enough to provide a stable and durable rotary-table body. This makes it a practical option for precision fixture rotation, component orientation, compact transfer stations, and positioning tasks where repeatability and table stability matter more than raw output size. That application view is a reasonable engineering conclusion based on the official model classification, precision emphasis, compact design language, and published size/weight data.
Typical Application Direction
In practical automation terms, the MSQA10R is best suited to precision indexing and presentation tasks. It is well matched to stations where a part must be rotated to a defined angle for inspection, labeling, assembly, sensor reading, or handoff to the next process step. Because it is a high-precision rotary table rather than a basic compact rotary unit, it is more appropriate when rotational accuracy and stable table behavior are meaningful selection criteria. This application guidance is an engineering inference grounded in SMC’s official description of the MSQA version as the high-precision type and the product page’s emphasis on durability and precision.
Conclusion
The SMC MSQA10R is a compact, precision-oriented pneumatic rotary table designed for automated equipment that needs more accurate rotational positioning than a standard basic-type unit. Official SMC sources identify it as an MSQ Series high precision type with internal shock absorber, size 10, with a 0 to 190° angle adjustment range, 190° maximum rotation, Ø15 mm bore, M5 × 0.8 porting, and an official product weight of approximately 539 g, excluding auto switch weight. From an engineering and commercial standpoint, its strongest selling points are its integrated table-and-actuator construction, high-precision series positioning, compact installation, and controlled end-of-stroke behavior through the internal shock absorber. For buyers who need a small but technically credible precision rotary table, the MSQA10R is a solid and well-defined SMC option.
