fixture stops and compact production equipment
EP-SCS15 is a single-split aluminum shaft clamp with a 15 mm nominal bore, 35 mm outside diameter, 12 mm width and M5 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-SCS15 Fits Best
A 15 mm bore gives machine builders another intermediate metric option without moving up to a 16 mm shaft. The 35 mm outside diameter, 12 mm width and M5 screw place this model in a compact but more robust envelope than the smallest collars.
EP-SCS15 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 35 mm outside diameter and 12 mm width should be treated as real interface dimensions, not secondary details after the 15 mm bore is chosen.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS15 | 15 mm | 35 mm | 12 mm | M5 | 1.5 mm | 5 mm |
Selection starts with the measured shaft diameter, then moves to the surrounding envelope. Confirm the 35 mm outside diameter, 12 mm axial width and access to the M5 screw against the real assembly before treating EP-SCS15 as a replacement or new-build fit.
Interface Review
When used as a fixture stop, define where the contact occurs and whether the collar is intended only as a position reference or may experience repeated impact. That distinction changes the questions that should be reviewed before release.
The EP-SCS chart lists K = 5 mm for the keyed option on EP-SCS15, 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-SCS15 can serve as a removable stop on a 15 mm guide shaft, an axial reference beside another shaft-mounted component, or one side of a paired locating arrangement. Its 12 mm body width and 35 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-SCS15 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 15 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
The split-clamp style supports repositioning during setup, so leave enough tool access to loosen and reset the collar. A position that is easy to install initially can become difficult to service once surrounding tooling is added.
When EP-SCS15 is used in automation or retrofit work, compare its 35 mm OD and 12 mm width with bearing blocks, couplings, guards and moving carriages. Orient the M5 screw toward a serviceable side so the 15 mm collar can be adjusted later without avoidable disassembly.
The EP-SCS15 body is tightened through its M5 clamp screw and the listed split W is 1.5 mm. Install it on a clean 15 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-SCS15. 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-SCS15 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 35 mm × 12 mm envelope can be checked against the installation rather than inferred from the machine name.
Nearest EP-SCS Bore Options
EP-SCS15 is centered on a 15 mm shaft interface. Nearby catalogue entries such as EP-SCS14 and EP-SCS16 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 35 mm OD and 12 mm width as separate envelope checks.
RFQ Focus for EP-SCS15
Include the measured shaft, expected adjustment frequency and any keyway need. A simple dimensioned fixture sketch is usually enough to clarify the required axial location and radial clearance.
For EP-SCS15, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 15 mm shaft dimension, quantity and any restricted 35 mm OD / 12 mm width envelope so the quotation addresses the real assembly.
