Universal Robots (UR) uses structured part numbering conventions to identify components across collaborative robot arms, control systems, and peripheral modules.
This index page provides a system-level reference for understanding how Universal Robots part numbers are organized, grouped, and interpreted within UR cobot systems.
Rather than listing individual products or commercial SKUs, this page focuses on part number structure, functional classification, and architectural context, serving as a neutral reference for identification and orientation.
Core Reference: Part Number Structure & Classification Logic
Universal Robots part numbers are designed to reflect component role, subsystem association, and platform relevance.
Although formats may vary across product generations, part numbers generally align with functional subsystems and robot platform architecture, rather than universal interchangeability.
| Classification Layer | Typical Scope | Identification Role |
|---|---|---|
| Functional Subsystem | Arm, control, interface, power | Defines the system role of the component |
| Product Platform | UR-series collaborative robots | Indicates the target robot architecture |
| Assembly Group | Module or subassembly | Groups components by structural function |
| Variant / Revision | Configuration-specific | Differentiates versions or revisions |
This abstraction reflects how Universal Robots structures component identification at a system level.
1. Functional Subsystems
UR robot parts are categorized by broad functional subsystems within the collaborative robot framework. Common subsystems include:
- Robotic Arm & Joint Assemblies: Specific modules for UR3, UR5, UR10, and UR16 arms.
- Control Units & Processing Hardware: CPU boards and safety controllers inside the control box.
- Safety & Interface Modules: I/O modules, teach pendants, and safety PLC components.
- Power Supply & Communication: Harnesses, power modules, and networking cards.
2. Robot Platforms & Generations
Within each functional subsystem, part numbers are linked to specific robot platforms or product generations.
At an index level, this association indicates:
- Architectural compatibility boundaries: E.g., e-Series joints are not compatible with CB3 arms.
- Mechanical and electrical integration scope
- Platform-specific design constraints
Platform alignment is essential for orientation but does not imply direct part interchangeability.
3. Assembly-Level Identification
Universal Robots part numbers often correspond to assemblies or modular components rather than discrete elements.
Assembly-level grouping helps clarify:
- Component hierarchy within the UR cobot system
- Functional relationships between modules(e.g., a specific cable harness for a specific joint).
- Service and replacement boundaries
This level supports structural understanding without exposing individual commercial variants.
4. Variant & Revision Context
Suffixes or extensions within part numbers typically represent revisions, configuration differences, or regional adaptations.
At an index level, these elements indicate:
- Design iteration or lifecycle stage
- Hardware or firmware alignment
- Manufacturing or compliance variation
They are not sufficient on their own to determine compatibility.
5. Identification & Classification Scope
When interpreting Universal Robots part numbers, the following principles apply:
- Part numbers encode system context, not guaranteed interchangeability
- Subsystem and platform alignment precede revision interpretation
- Similar numbering patterns may exist across different robot generations
This index clarifies how Universal Robots part numbers are structured and grouped, not how to perform direct replacement decisions.
Frequently Asked Questions
Q1: Do Universal Robots part numbers define direct compatibility?
No. They provide identification and classification context within a specific robot architecture.
Q2: Can similar part number formats indicate interchangeable components?
Not necessarily. Similar formats may span different robot generations or subsystems.
Q3: Why are UR part numbers indexed by structure instead of product lists?
Structural indexing reflects Universal Robots modular system design and supports long-term reference use.
