compact guide shafts and light bench automation
EP-SCS08 is a single-split aluminum shaft clamp with a 8 mm nominal bore, 30 mm outside diameter, 10 mm width and M4 clamp screw. It is intended for axial positioning and stop duties on round shafts where a clamp-style collar gives the installer a removable, repositionable mechanical reference.
Where EP-SCS08 Fits Best
An 8 mm shaft often appears in compact guides and light automation, but the surrounding space can be more restrictive than the bore. This model uses a 30 mm outside diameter, so confirm carriage and frame clearance before treating it as a drop-in stop.
EP-SCS08 sits in the compact end of the EP-SCS range, where bore accuracy and nearby component clearance usually matter more than overall mass. It is well suited to evaluation for guide rods, small fixtures, sensors, light linear mechanisms and benchtop automation where a removable stop or axial reference is needed.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS08 | 8 mm | 30 mm | 10 mm | M4 | 1.5 mm | — |
Selection starts with the measured shaft diameter, then moves to the surrounding envelope. Confirm the 30 mm outside diameter, 10 mm axial width and access to the M4 screw against the real assembly before treating EP-SCS08 as a replacement or new-build fit.
Interface Review
Replacement buyers should record both the shaft size and the old collar width. Matching only the bore can leave an assembly with interference at a nearby bracket, guard or bearing support.
EP-SCS dimensional data for EP-SCS08 does not include a standard keyway K value. The normal selection path is therefore the plain-bore collar; if a keyed interface is required, include the shaft and key geometry in the enquiry so feasibility can be reviewed for the actual assembly.
Typical Positioning Roles
EP-SCS08 can serve as a removable stop on a 8 mm guide shaft, an axial reference beside another shaft-mounted component, or one side of a paired locating arrangement. Its 10 mm body width and 30 mm outside diameter must fit the surrounding mechanism; bearings, couplings, keys and other functional components should continue to perform the duties assigned to them by the machine design.
If EP-SCS08 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 8 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
When the collar is repositioned during setup, orient the split so the clamp screw remains accessible after the rest of the mechanism is assembled. That simple choice can avoid disassembly during later adjustment.
For compact EP-SCS08 installations, check the full motion path around the 30 mm OD body before fixing the stop position. Leave a practical tool path to the M4 screw and confirm that the 10 mm axial width does not crowd an end plate, sensor bracket or moving carriage.
The EP-SCS08 body is tightened through its M4 clamp screw and the listed split W is 1.5 mm. Install it on a clean 8 mm shaft, seat the collar squarely, keep the screw accessible, and verify the axial position again after tightening before the mechanism returns to service.
Configuration Details to Confirm
The size chart defines the core geometry for EP-SCS08. If the application depends on a specific tightening torque, axial holding requirement, aluminum grade, surface treatment or compliance document, state that requirement in the RFQ so it can be confirmed for the ordered configuration rather than assumed from bore size alone.
When EP-SCS08 is being considered as a replacement, record the actual shaft diameter together with the old collar outside diameter, width and screw orientation. Also note nearby shoulders, bearing hardware and visible shaft condition so the 30 mm × 10 mm envelope can be checked against the installation rather than inferred from the machine name.
Nearest EP-SCS Bore Options
EP-SCS08 is centered on a 8 mm shaft interface. Nearby catalogue entries such as EP-SCS06 and EP-SCS10 are useful for comparing the range, but they should not be used to compensate for an uncertain shaft measurement. Verify the shaft first, then treat the 30 mm OD and 10 mm width as separate envelope checks.
RFQ Focus for EP-SCS08
Include a photo of the installed area and the maximum allowed outside diameter. No standard K value is shown for this model, so a keyway request needs mating-shaft information rather than a generic option code.
For EP-SCS08, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 8 mm shaft dimension, quantity and any restricted 30 mm OD / 10 mm width envelope so the quotation addresses the real assembly.
