Choose a hydraulic indexing table by matching its load capacity, indexing accuracy, station layout, cycle requirements, and mounting interface to the actual needs of your machine. Start with the workpiece and fixture—not just the part weight—and confirm how the table will be controlled, locked, and maintained in your production environment. At HAEGOLIA, we recommend sharing these details with your supplier before selecting a standard model or requesting a custom configuration.

A hydraulic indexer can move a fixture or workpiece between preset positions and hold it for operations such as machining, assembly, inspection, or transfer. The right configuration depends on the combined forces and moments applied during operation, the required positioning performance, and how the table integrates with the rest of the machine. The steps below provide a practical framework for evaluating options and preparing a useful supplier inquiry.
Begin by explaining what the table needs to do at each position. Note whether it rotates a fixture between machining stations, presents parts for assembly, or indexes components for inspection. Also state whether the table operates independently or must coordinate with a CNC machine, PLC, robot, or other automation.
Describe the production pattern, including how often the table indexes and whether it moves while loaded. If the process includes cutting, clamping, drilling, or other forces, identify their direction and approximate magnitude where known. These details help a supplier assess more than static load capacity alone.
Include the workpiece, fixture, tooling, and any components that rotate with the table. Then describe where the load sits relative to the table center. An off-center load can create an overturning moment, so its location may be as important as its mass.
For an initial inquiry, you might document a hypothetical 80 kg combined fixture-and-workpiece load and note that its center of gravity is 150 mm from the rotation axis. These values are examples for illustrating what to report, not product ratings or a recommended design. Ask the supplier to confirm permissible axial, radial, and moment loads for the proposed model and operating conditions.
Specify the number of positions and the angular spacing required. For example, four evenly spaced positions correspond to 90° between stops, while six evenly spaced positions correspond to 60°. If the station spacing is unequal, provide a position diagram or a list of target angles rather than assuming a standard equal-division arrangement.
State how quickly the table must index, how long it pauses at each position, and whether the motion must be smooth or synchronized with another machine. A requested cycle time should be reviewed alongside load inertia, hydraulic supply, control method, and stopping requirements. Do not select a table on indexing speed alone if the application also requires repeatable positioning under process load.
Clarify whether your process needs repeatability, absolute positioning accuracy, or both. These terms are not interchangeable: repeatability concerns the consistency of returning to a position, while accuracy concerns closeness to the intended position. Ask how the supplier defines and verifies each stated performance value, and whether it applies under your load and operating conditions.
Also confirm how the table holds its position during machining or assembly. The required locking or clamping arrangement depends on process forces and the machine design. Share any known cutting forces, required dwell conditions, and safety expectations so that the holding method can be evaluated as part of the complete system.
Compare the available installation space with the table’s envelope, height, mounting pattern, and workpiece-clearance needs. Confirm the orientation of hydraulic ports, cable or sensor connections, and any access needed for maintenance. A dimensioned drawing is more useful than a general description when checking interference with guards, tools, conveyors, or adjacent stations.

Ask your engineering and supplier teams to confirm hydraulic pressure and flow requirements against the available power unit. The values must remain within the limits specified for the selected table and the wider hydraulic circuit; do not assume that a machine’s existing supply is compatible. Also identify the control signals, feedback, interlocks, and sequence logic needed for the intended equipment.
A standard configuration may be appropriate when its load, station arrangement, interfaces, and operating conditions match the application. If your workpiece is unusually shaped, the fixture is offset, the machine space is restricted, or the index pattern is non-standard, ask whether a modified or engineered configuration is available. Compare the implications for validation, integration, maintenance, and delivery—not just the initial purchase price.
Hydraulic actuation may suit applications that already have a compatible hydraulic system or need a supplier-reviewed solution for their operating loads. However, the complete setup must be considered, including the power source, valves, hoses, controls, fluid management, and service access. Describe the temperature, contamination, washdown, and duty conditions that the table will encounter, and request confirmation of suitability rather than relying on assumptions.
Before purchase, establish which drawings, interface details, maintenance instructions, and spare-part information will be supplied. Clarify what inspections or routine service the manufacturer recommends and how replacement components are identified. This helps your team plan integration and support over the equipment’s working life.
Prepare a concise application brief before requesting a quotation. Include a general arrangement drawing, the load and center-of-gravity information, the required index positions, cycle expectations, machine interfaces, and operating environment. Mark unknown values clearly instead of presenting estimates as confirmed specifications.
Ask suppliers to identify assumptions and open technical questions in their proposal. Request confirmation of the table’s rated loads, positioning performance, hydraulic requirements, and compatibility with your installation conditions. If a value depends on a specific fixture, speed, or duty cycle, have that condition stated in writing so the engineering review addresses the real application.
When comparing quotations, review the proposed configuration and scope as well as the price. Check whether controls, hydraulic components, sensors, mounting features, drawings, and commissioning support are included or offered separately. A clear scope makes it easier to assess technical fit and reduces the risk of discovering interface gaps late in the project.
As a supplier serving mechanical parts and fabrication requirements, HAEGOLIA can review the application information and discuss a suitable hydraulic indexing table configuration. We encourage buyers to provide the intended operation, load details, index pattern, available installation space, and machine interface requirements. Where information is incomplete, we can help identify which measurements or operating details are needed for a meaningful technical review.
To begin, send your application brief, layout or mounting drawing, and target production sequence to our team for review. Include your expected quantity and project timing so that the quotation can address the relevant supply scope. We can then discuss whether a standard solution or a configuration requiring further engineering review is the better route for your application.
The best hydraulic indexing table is the one whose verified capacity, indexing layout, positioning performance, interfaces, and service requirements align with your complete application. Start with the load and process, define the motion and holding needs, and confirm installation and hydraulic compatibility before placing an order. Share those requirements with HAEGOLIA to support a focused supplier review and a more informed selection.
