The SMC MSQB10R is a compact pneumatic rotary table in SMC’s MSQ series, built in the MSQB basic type configuration and identified by the suffix R, which denotes the internal shock absorber type. In SMC’s own product description, the MSQ series integrates the table and the rotary actuator into one unit, includes an angle adjustment mechanism, and is designed to make centering during load mounting and body mounting easier. That product architecture is important because it places the MSQB10R somewhere between a simple rotary actuator and a more application-ready indexing platform.
For machine designers, the attraction of the MSQB10R is not just that it rotates. It is that it provides rotary motion in a compact format with a directly usable table surface, controlled end-of-stroke behavior, and an established SMC mounting concept. Because the actuator and table are integrated, the mechanical layout can be simpler than a separate-shaft actuator plus custom turntable arrangement. In practical automation, that usually means fewer alignment variables, a cleaner structure, and easier repeatability across multiple machine builds. This is an engineering interpretation based on SMC’s official integrated-table design description for the MSQ family.

Specification basis: SMC’s MSQ catalog lists the basic type / internal shock absorber / size 10 weight as 510 g, excluding auto switch weight. The same official catalog gives 1.0 MPa maximum operating pressure, 0.2 MPa minimum operating pressure for the internal shock absorber type, 0 to 60°C ambient and fluid temperature, 0 to 190° angle adjustment range, 190° maximum rotation, Ø15 mm bore size, and M5 × 0.8 porting for size 10. SMC’s web catalog for MSQB10R-M9BW also confirms that size 10 with suffix R is the internal shock absorber version, and that size 10 uses M5 porting.
Model Identity and What It Means
Understanding the model code is useful when this product appears in quotations, spare-parts lists, or machine documentation. In SMC’s official catalog structure, MSQB indicates the basic type, while MSQA is the high precision type. That means the MSQB10R should not be confused with the MSQA10R. It belongs to the standard basic branch of the series rather than the higher-precision branch. For buyers, that distinction matters because it affects expected positioning characteristics, cost positioning, and application fit. The MSQB10R is better understood as a compact general-purpose rotary table with internal shock absorption rather than as a premium precision indexing unit.
The suffix R is equally important. SMC’s web catalog clearly identifies R as the internal shock absorber version. This gives the product a smoother end-of-rotation stopping behavior than a simple adjustment-bolt-only design. In repetitive automation cycles, that can reduce impact transmitted into the table, tooling, and mounted workpiece. It can also support more stable operation where loads have modest inertia and the machine builder wants controlled deceleration near the rotation end. This functional implication follows directly from SMC’s designation of the R type as the internal shock absorber version and from the catalog’s kinetic-energy and rotation-time guidance for that version.
Mechanical Design Advantages
One of the strongest engineering points of the MSQB10R is its integrated layout. SMC states that the MSQ family combines the table and the rotary actuator in one body and includes an angle adjustment mechanism. In a practical machine, that can save space and reduce the amount of intermediate hardware that would otherwise be needed. Instead of building a rotary station from a separate actuator, shaft, hub, and fixture plate, the designer starts from a unit that already provides the rotating table interface. That usually shortens assembly time and reduces the risk of tolerance stack-up.
The internal shock absorber design also influences how the product behaves mechanically. The official SMC catalog includes allowable kinetic energy and rotation-time guidance for the internal shock absorber type, which shows that the product is intended to absorb end-of-stroke energy within defined limits rather than simply stop on a hard mechanical impact. That is relevant when evaluating service life, cycle consistency, and the suitability of the product for light-to-moderate inertia loads. The catalog also states that, for size 10, the minimum rotation angle that will not allow a decrease of energy absorption ability is 52°, which is a useful detail during setup. If the rotation is set below that level, shock-absorber effectiveness is reduced.
Rotation Range and Control Characteristics
The MSQB10R is not limited to one fixed stroke angle. SMC’s official catalog states that the MSQ series supports an angle adjustment range from 0 to 190° and a maximum rotation of 190°, and it explicitly notes that the rotation angle can also be set on the type with internal shock absorber. That makes the MSQB10R more versatile than a fixed-angle unit. In actual automation, many fixtures do not need exactly 90° or 180° movement. Some need custom presentation angles for inspection, labeling, loading, unloading, or transfer. The adjustable-angle design allows the product to fit those machine geometries more naturally.
SMC also provides a useful setup reference: for size 10, the adjustment angle per rotation of the angle adjustment screw is 10.2°. That helps during commissioning because it gives the technician a predictable basis for adjusting the final rotary end position. The official catalog further states that the rotary table turns clockwise when the A port is pressurized and counter-clockwise when the B port is pressurized. Clear directional logic like this simplifies pneumatic circuit design and troubleshooting, especially in small automated stations where maintenance access can be limited.
Pneumatic Specifications and Integration
From the pneumatic side, the MSQB10R fits common factory compressed-air systems. SMC specifies air (non-lube) as the working fluid, a maximum operating pressure of 1.0 MPa, and a minimum operating pressure of 0.2 MPa for the internal shock absorber type. The ambient and fluid temperature range is listed as 0 to 60°C without freezing. These are mainstream industrial values, which means the unit can usually be integrated without unusual supporting infrastructure or special utility requirements.
The official catalog lists the cylinder bore size as Ø15 mm for size 10 and shows M5 × 0.8 for both end and side ports at this size. That puts the MSQB10R firmly in the compact rotary-table category. It is not a heavy indexing table, but it is also not a miniature novelty actuator. Its scale makes it appropriate for compact tooling, part orientation modules, sensor presentation devices, and small transfer mechanisms where the goal is stable rotary positioning within a limited machine footprint. That application interpretation is grounded in the official bore, port, and series-structure data.
Product Weight and Why It Matters
For your requirement about product weight, the correct official figure for MSQB10R is 510 g, and SMC explicitly notes that this value does not include auto switch weight. That figure comes from SMC’s published weight table for the MSQB basic type with internal shock absorber, size 10. This is the number that should be used in technical product descriptions, quotation sheets, and structured listing data when the product is identified as MSQB10R.
From an engineering perspective, a weight of 510 g places the MSQB10R in a useful middle zone for compact automation. It is light enough to mount on standard machine frames, slides, or subassemblies without imposing a large structural penalty, yet substantial enough to function as a stable rotary body rather than a fragile miniature actuator. For many OEM designs, that balance is desirable because it helps keep the overall module compact while still providing mechanical confidence in repeated duty. This practical interpretation follows from the official size and mass data.
Commercial and Application Value
In commercial terms, the MSQB10R is best positioned as a compact SMC rotary table for part orientation, small fixture rotation, indexing, and presentation-angle control in pneumatic automation. That application profile is not copied from a marketing line; it is an engineering inference based on the product’s integrated table structure, adjustable angle mechanism, internal shock absorber type, compact size, and standard pneumatic specification set. In other words, the MSQB10R is best understood as a ready-to-integrate rotary motion module for light industrial automation rather than as a generic rotary shaft actuator.
It is particularly suitable where the machine builder wants a compact unit that can be mounted easily, adjusted to the desired end angle, and cycled repeatedly with controlled end-of-stroke behavior. For assembly equipment, test fixtures, inspection stations, and transfer modules, those characteristics often matter more than absolute output size. The product’s internal shock absorber and adjustable range make it easier to adapt to real machine geometry than a fixed, non-damped rotating device.
Conclusion
The SMC MSQB10R is a compact MSQ series rotary table in the MSQB basic type configuration with an internal shock absorber. Official SMC sources support the following core facts: size 10, air non-lube operation, 1.0 MPa maximum operating pressure, 0.2 MPa minimum operating pressure, 0 to 60°C operating temperature, 0 to 190° angle adjustment range, 190° maximum rotation, Ø15 mm bore, M5 × 0.8 porting, and an official product weight of 510 g excluding auto switch weight. For buyers who need a compact, practical, and technically credible pneumatic rotary table, the MSQB10R is a strong fit for small automation systems that require adjustable rotary positioning with controlled end-of-stroke behavior.
