STEP SR Industrial Robots
STEP SR industrial robots in this comparison cover twelve six-axis configurations for different handling loads and work envelopes. Compare payload, reach, robot mass and protection by model rather than treating the SR family as one fixed-capacity robot.

Handling, tooling and working envelope
SR60-2280B is listed with a 55 kg maximum payload, despite the 60 in its name. The 175 and 280 groups include different reaches and masses. Choose the exact mechanical version and controller package before planning a gripper, pedestal or replacement installation.
A handling robot moves the complete tool-and-part assembly between defined poses. Start with the gripper, adapters, services and workpiece, then check wrist moments and inertia for the chosen motion. A reach dimension describes the robot geometry; usable access also depends on tool length, wrist orientation, machine openings and fixtures. For assembly, define how the part is located and how insertion or seating is confirmed. For machine tending, include door travel, chuck or fixture status, chips, coolant and the recovery position. These details distinguish an arm-only purchase from a working transfer system.

Define what you need supplied
Robot package
Specify arm, controller, pendant, software and cables by exact version.
Tooling package
Add the gripper, adapters, sensors and part presentation required by the task.
Integrated transfer
Define machine interfaces, protection, programming and on-site commissioning separately.
Match the equipment to your installation
Plan the pedestal, anchoring and cable route around the robot mass and moving envelope. Match the offered controller, fieldbus, safety connections and electrical supply to the site. Keep access for mastering, grease points, connectors and tool replacement. During commissioning, check loaded paths, part-present signals, loss of grip, controlled stops and restart with the intended part family.
| Selection factor | Information to specify |
|---|---|
| Moving load | Part, gripper, adapters and services; include center of gravity and inertia at the wrist. |
| Pick and place positions | Coordinates, tool orientation, insertion depth and clearance at every handoff. |
| Grip and part detection | Contact surfaces, part variation, confirmation signals and the response to a missed pick. |
| Machine interface | Controller version, door/fixture sequence, I/O and a defined recovery state. |

Product and ordering questions
01What are the applications of STEP SR Industrial Robots?+
STEP SR industrial robots in this comparison cover twelve six-axis configurations for different handling loads and work envelopes. Compare payload, reach, robot mass and protection by model rather than treating the SR family as one fixed-capacity robot.
02Does robot payload equal the allowed part weight?+
No. The moving load includes the gripper, adapters, hoses and part. Its center of gravity, wrist moments and inertia must also fit the selected robot and motion. A part below the nominal payload can still require a different tool or robot because of its dimensions and offset.
03What should I consider when choosing STEP SR Industrial Robots?+
SR60-2280B is listed with a 55 kg maximum payload, despite the 60 in its name. The 175 and 280 groups include different reaches and masses. Choose the exact mechanical version and controller package before planning a gripper, pedestal or replacement installation.
04What should the equipment package include?+
Identify the selected equipment and separate the following packages: robot package, tooling package, integrated transfer. State which accessories, controls, installation, programming and commissioning are included. This makes equipment-only and integrated proposals comparable without assuming identical supply scope.
05How can I request a quotation for STEP SR Industrial Robots?+
Send the required model or arrangement, quantity and destination, plus part, gripper, adapters and services; include center of gravity and inertia at the wrist; coordinates, tool orientation, insertion depth and clearance at every handoff. Add photographs or drawings and identify existing equipment. TubeFrame can then discuss model sourcing, configuration and partner-supported integration as separately defined work packages.
