Match the Right Component to Your Clamping System
Replacing a small component can stop a much larger machine from returning to service if the interface, size or system is wrong. Röhm accessories & connection sets support compatible machine-tool, workholding & clamping systems where accurate component identification is critical.
Start with the existing Röhm equipment, its model, size & item number wherever possible. Workshop Equipment supports broader machine-maintenance work, while Measuring & Layout Tools can assist with dimensional checks during component identification. Industrial Shed also carries Röhm products across other specialised workholding collections, making it easier to investigate related components when a repair extends beyond one accessory.
What Are Röhm Accessories & Connection Sets?
Röhm produces supporting components for numerous machine-tool clamping & workholding systems.
Depending on the product family, these can include components associated with HSK or SK tool clamping, RESK machine-component interfaces, SPK pallet clamping plus other Röhm workholding arrangements.
Their jobs are not interchangeable.
One component may form part of the clamping mechanism. Another may provide the connection between two assemblies. A separate component may establish centring, provide mounting or assist with assembly & servicing.
Depending on the system, relevant component types can include:
► Clamping sets
► Adapter components
► Mounting components
► Draw-in components
► Clamping-system accessories
► Assembly tools
► Interface components
► Replacement hardware
► System-specific service accessories
The correct choice starts with identifying which Röhm system the component belongs to.
Why Choose Röhm Accessories & Connection Sets?
Machine-tool interfaces depend on specific relationships between components.
A part that looks similar or shares one matching dimension is not necessarily compatible with the equipment already installed.
Correct identification becomes particularly important when maintaining:
► HSK tool-clamping systems
► SK tool-clamping systems
► Machine spindles
► Machining centres
► Röhm RESK interfaces
► Röhm SPK pallet-clamping systems
► Lathe-chuck assemblies
► Machine vices
► Other Röhm workholding equipment
Matching the replacement to the existing product family, interface & size helps avoid ordering a component intended for a different Röhm system.
For assemblies that need to be securely held during inspection or servicing, Clamps & Vises provide useful supporting workshop equipment.
Common Applications
HSK tool clamping
Compatible Röhm HSK systems use dedicated clamping components according to the particular interface, size & system configuration.
SK tool clamping
Röhm also manufactures automatic clamping systems for steep-taper tooling, with system-specific clamping components forming part of the spindle arrangement.
Machine-component connection
Röhm RESK provides an interface for connecting compatible interchangeable machining units, tools or workpiece carriers to large machine tools & machining centres.
Pallet clamping
Röhm SPK systems use dedicated components on opposing sides of the interface for connecting & centring compatible pallets.
Machine-tool maintenance
Maintenance teams may need replacement components, mounting hardware or system accessories when inspecting, repairing or recommissioning existing equipment.
Workholding servicing
Chucks, vices & related workholding assemblies can require their own system-specific supporting parts during maintenance.
Machine setup & installation
Correct mounting, interface identification & alignment can be important when installing or replacing specialised workholding components.
Where machine geometry also needs checking, Alignment Tools (Laser, Dial, Manual) support broader setup & maintenance work.
Product Selection Guide
The fastest route to the correct component is usually system first, part second.
Identify the Main Röhm Equipment
Before measuring a loose component, identify what it came from.
Look for:
► Röhm product family
► Model designation
► Item number
► Equipment size
► Chuck or vice identification
► HSK or SK designation where applicable
► RESK or SPK system identification where applicable
► Machine manufacturer or spindle information where relevant
A description such as “Röhm connector” or “Röhm clamping part” may not provide enough information to identify a replacement.
Identify the Interface
Next, determine what the component connects to.
Röhm's tool-clamping portfolio includes several distinct systems. HSK, SK, RESK & SPK should not be treated as alternative names for the same interface.
Ask:
► Is this part of an HSK tool-clamping system?
► Is it associated with an SK steep-taper arrangement?
► Does it belong to a RESK machine-component interface?
► Is it part of an SPK pallet-clamping arrangement?
► Is it associated with a chuck, vice or another Röhm workholding product?
Getting this distinction right can eliminate many unsuitable components immediately.
Work Out What the Component Does
Connection, clamping, centring & mounting are different jobs.
Determine whether the required component:
► Generates or transfers clamping force
► Connects opposing parts of an interface
► Provides centring
► Mounts an assembly
► Retains another component
► Assists assembly or removal
► Supports lubrication or servicing
► Replaces existing system hardware
Understanding its function is particularly useful when an old component has incomplete markings.
Confirm the Size
Once the system is known, check its relevant size designation.
Depending on the product, this might involve:
► Interface size
► Chuck size
► Clamping-system size
► Thread
► Diameter
► Length
► Mounting dimensions
► Existing component number
Calipers (Digital / Manual) can help confirm accessible dimensions, but measurements should support identification rather than replace the manufacturer's product information.
Use the Röhm Item Number Wherever Possible
A readable Röhm item number can significantly reduce ambiguity when replacing an existing component.
Before dismantling an unfamiliar assembly, photograph:
► Identification plates
► Product markings
► Component orientation
► Interface arrangement
► Adjacent components
► Existing fastener positions
► Any numbers stamped or engraved into the component
That information can become extremely valuable once the assembly is apart.
Connection, Clamping or Centring?
These functions are easy to group together during a parts search, but they should remain separate when identifying the actual component.

A particularly useful example is pallet clamping. Within compatible Röhm SPK arrangements, the component responsible for connection is not automatically the same component responsible for centring.
That is why identifying the function within the assembly is as important as matching a visible dimension.
Expert Tips
Start at the machine—not the loose part.
A loose component on the bench may be difficult to identify. The machine, chuck, spindle or clamping system it came from usually provides better information.
Record both sides of an interface.
If the component connects two assemblies, document both. Knowing only one side can leave an important compatibility question unanswered.
Never order from appearance alone.
Similar-looking machine components can differ in thread, interface geometry, dimensions, size or intended clamping system.
Photograph before dismantling.
A few clear images can preserve orientation & assembly information that becomes difficult to reconstruct later.
Keep the original component.
Even damaged parts can provide item numbers, dimensions, thread information or other identification clues.
Keep system-specific accessories together.
Separating machine-specific adapters, mounting components & service tools from general workshop hardware reduces the chance of mixing similar parts. Tools Storage & Organization can help establish a dedicated location for specialised machine components.
Clean identification surfaces before measuring.
Grease, coolant residue & machining debris can conceal markings or affect accessible measurements. Tool Maintenance Kit supports routine cleaning around workholding equipment.
