        Overview Manuals Load Fit Mounting Plan Motion Checks Applications

        Features:

        • Integrated rotating platform: The actuator and table share one compact assembly for direct fixture mounting.
        • Multiple mounting approaches: Reference surfaces support space-conscious top, side or bottom installation planning.
        • Application-sized motion: Load inertia and rotation time remain the governing selection factors, not the nominal size alone.
        MSQB7A provides rotary positioning for tooling or workpieces but does not define the complete speed-control or stop system.

        Fixture mass must be converted into inertia about the rotation axis before the available kinetic-energy margin is judged.

        Commissioning should inspect piping movement, end-position repeatability and shock at the actual production rate.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Inertia calculation: Use the real fixture mass and its distance from the rotation center.
        • Cycle demand: Faster rotation increases kinetic energy and may change the acceptable load boundary.
        • External forces: Keep side loads and machining forces within the intended rotary-table duty.
        • Safety margin: Select from the most demanding operating condition rather than the average cycle.
        • Reference features: Locate the fixture from the intended boss or hole instead of relying on bolt clearance.
        • Base rigidity: A flexible bracket can appear as rotary backlash or poor repeatability.
        • Piping path: Route tubes so they do not pull the table or interfere through the full motion.
        • Service access: Preserve access to ports, adjusters and mounting fasteners after the fixture is installed.
        • End impact: Reduce speed or change the stop method when the table strikes the end position harshly.
        • Position proof: Verify both mechanical position and any switch indication before releasing downstream motion.
        • Leak diagnosis: Compare both directions to separate supply restriction from actuator leakage.
        • Fixture balance: An offset load can create different motion behavior in clockwise and counterclockwise travel.
        • Assembly indexing: Rotates a fixture between loading and work positions in compact equipment.
        • Part orientation: Turns components for inspection, transfer or packaging operations.
        • Tool presentation: Presents a mounted device to two controlled angular positions.
        • Machine replacement: Restores a documented MSQB7A axis after inertia, piping and mounting checks are repeated.
        Description
        By combining the rotary actuator and work table in one assembly, MSQB7A gives a compact machine a practical index axis for turning a fixture, nest or inspection station. The integrated table removes the need to design a separate coupling and bearing support for light rotary work.

        Correct selection starts with the moving fixture, not the nominal size of MSQB7A. Load inertia, centre-of-gravity radius and required rotation time determine the stopping energy, so the real tool and workpiece should be included in the calculation.

        Flow controls, piping clearance and any required external stops belong to the completed installation around MSQB7A. After assembly, cycle the loaded table through both end positions and confirm stable stopping before enabling automatic production.
        Alternative Names
        MSQB7A
        Technical notes
        Calculate load inertia and kinetic energy at the required rotation time before installing MSQB7A. Provide flow controls and mechanical support so the table is not used as a structural stop. Align the mounted fixture from the documented reference features, keep piping clear through the full stroke and verify both end positions under production load.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        A fixture fits physically on MSQB7A. What calculation is still required before the table is approved?
        Calculate rotational inertia and kinetic energy at the intended speed, including the fixture and every carried component.
        MSQB7A hits one end harder than the other. Which checks should precede actuator replacement?
        Compare flow controls, tube restrictions, fixture balance, external interference and stop adjustment in both directions.
        Can MSQB7A act as the hard stop for a mechanism driven by another actuator?
        Avoid that unless specifically engineered; external loads can exceed the rotary table's intended stop and bearing duty.
        An MSQB7A replacement reaches position but the machine receives no confirmation. What should be separated?
        Verify mechanical arrival first, then inspect switch selection, mounting, wiring and controller input as a separate chain.
        The mounted load on MSQB7A was moved farther from the center. Does unchanged mass preserve suitability?
        No. Increased radius raises inertia, so the application calculation and acceptable rotation time must be reviewed.
        A quotation lists MSQB7A without switches or flow controls. Is that necessarily incomplete?
        Not necessarily. Those items are selected separately; require the quotation to state exactly which accessories are included.
