actuator shafts and larger automation modules
EP-SCS30 is a single-split aluminum shaft clamp with a 30 mm nominal bore, 55 mm outside diameter, 15 mm width and M6 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-SCS30 Fits Best
EP-SCS30 introduces a 15 mm body width and M6 screw with a 55 mm outside diameter. This makes the 30 mm bore model a stronger visual and spatial presence than the smaller automation sizes, so machine-envelope review becomes increasingly important.
EP-SCS30 belongs to the larger-bore portion of the EP-SCS range and should be reviewed as part of the complete machine interface rather than as a bore-only item. Its 55 mm outside diameter and 15 mm width make radial space, axial space and service access increasingly important in machinery and retrofit layouts.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS30 | 30 mm | 55 mm | 15 mm | M6 | 1.5 mm | 8 mm |
Selection starts with the measured shaft diameter, then moves to the surrounding envelope. Confirm the 55 mm outside diameter, 15 mm axial width and access to the M6 screw against the real assembly before treating EP-SCS30 as a replacement or new-build fit.
Interface Review
Check radial clearance around actuators, bearing housings and guards, and verify that a tool can reach the M6 clamp screw. The larger body should be treated as a designed machine component rather than an afterthought in a crowded assembly.
The EP-SCS chart lists K = 8 mm for the keyed option on EP-SCS30, while the standard collar is supplied without a keyway. A keyed request should include the mating key and shaft details because the K value is only one dimension of the complete interface.
Typical Positioning Roles
EP-SCS30 can serve as a removable stop on a 30 mm guide shaft, an axial reference beside another shaft-mounted component, or one side of a paired locating arrangement. Its 15 mm body width and 55 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-SCS30 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 30 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
If the collar is used as a serviceable stop, decide whether maintenance staff need to reposition it routinely. That affects preferred screw orientation and whether nearby covers should allow direct access.
For the larger EP-SCS30 interface, reserve working space around the M6 screw as well as the full 55 mm radial envelope and 15 mm body width. If the 30 mm shaft stop will see repeated impact, meaningful axial demand or another demanding duty, state that condition in the RFQ so it can be reviewed for this configuration.
The EP-SCS30 body is tightened through its M6 clamp screw and the listed split W is 1.5 mm. Install it on a clean 30 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-SCS30. 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-SCS30 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 55 mm × 15 mm envelope can be checked against the installation rather than inferred from the machine name.
Nearest EP-SCS Bore Options
EP-SCS30 is centered on a 30 mm shaft interface. Nearby catalogue entries such as EP-SCS25 and EP-SCS35 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 55 mm OD and 15 mm width as separate envelope checks.
RFQ Focus for EP-SCS30
Provide a dimensioned assembly view showing the 55 mm outside envelope, shaft diameter and axial space. Note whether the 8 mm K option is required and describe any meaningful impact or axial-load condition.
For EP-SCS30, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 30 mm shaft dimension, quantity and any restricted 55 mm OD / 15 mm width envelope so the quotation addresses the real assembly.
