odd-size metric replacement and custom-machine work
EP-SCS13 is a single-split aluminum shaft clamp with a 13 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-SCS13 Fits Best
The 13 mm bore is valuable when a machine uses a less common metric shaft and a buyer wants to avoid opening a larger standard collar as a workaround. The 30 mm outside diameter and 10 mm body width give a compact envelope for that nominal shaft size.
EP-SCS13 is in the middle of the range and is a practical candidate for general automation, linear-motion hardware, fixture positioning and machine replacement work. The 30 mm outside diameter and 10 mm width should be treated as real interface dimensions, not secondary details after the 13 mm bore is chosen.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS13 | 13 mm | 30 mm | 10 mm | M4 | 1.5 mm | 4 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-SCS13 as a replacement or new-build fit.
Interface Review
Do not assume an unidentified 13 mm shaft is exactly on nominal size, particularly on worn equipment. Measure the shaft at more than one location if surface wear is visible and include the observed condition in the replacement enquiry.
The EP-SCS chart lists K = 4 mm for the keyed option on EP-SCS13, 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-SCS13 can serve as a removable stop on a 13 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-SCS13 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 13 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
This model can act as a simple stop or locator, but the actual holding requirement depends on the machine duty. If the collar will see repeated impact or meaningful axial force, describe that duty rather than treating bore size as a performance rating.
When EP-SCS13 is used in automation or retrofit work, compare its 30 mm OD and 10 mm width with bearing blocks, couplings, guards and moving carriages. Orient the M4 screw toward a serviceable side so the 13 mm collar can be adjusted later without avoidable disassembly.
The EP-SCS13 body is tightened through its M4 clamp screw and the listed split W is 1.5 mm. Install it on a clean 13 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-SCS13. 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-SCS13 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-SCS13 is centered on a 13 mm shaft interface. Nearby catalogue entries such as EP-SCS12 and EP-SCS14 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-SCS13
For replacement work, send measured shaft diameter, old collar dimensions and a clear photo. If the listed 4 mm keyway option is required, include the mating key dimensions as well.
For EP-SCS13, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 13 mm shaft dimension, quantity and any restricted 30 mm OD / 10 mm width envelope so the quotation addresses the real assembly.
