25 mm machinery shafts and production fixtures
EP-SCS25 is a single-split aluminum shaft clamp with a 25 mm nominal bore, 45 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-SCS25 Fits Best
The 25 mm model retains a 45 mm outside diameter and 12 mm width while using an M5 clamp screw. It suits mid-size production fixtures and machinery layouts that need a removable stop around a quarter-century metric shaft size.
EP-SCS25 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 45 mm outside diameter and 12 mm width should be treated as real interface dimensions, not secondary details after the 25 mm bore is chosen.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS25 | 25 mm | 45 mm | 12 mm | M5 | 1.5 mm | 8 mm |
Selection starts with the measured shaft diameter, then moves to the surrounding envelope. Confirm the 45 mm outside diameter, 12 mm axial width and access to the M5 screw against the real assembly before treating EP-SCS25 as a replacement or new-build fit.
Interface Review
Because the outside diameter matches EP-SCS22 while the bore grows, this model can be useful when the machine designer wants more shaft capacity without increasing the same outer envelope family. Still confirm the actual clearances before release.
The EP-SCS chart lists K = 8 mm for the keyed option on EP-SCS25, 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-SCS25 can serve as a removable stop on a 25 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 45 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-SCS25 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 25 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
For paired collars around another component, define the required location and free movement between them. The collars provide adjustable references, while the machine drawing should establish any working clearance or preload requirement.
When EP-SCS25 is used in automation or retrofit work, compare its 45 mm OD and 12 mm width with bearing blocks, couplings, guards and moving carriages. Orient the M5 screw toward a serviceable side so the 25 mm collar can be adjusted later without avoidable disassembly.
The EP-SCS25 body is tightened through its M5 clamp screw and the listed split W is 1.5 mm. Install it on a clean 25 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-SCS25. 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-SCS25 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 45 mm × 12 mm envelope can be checked against the installation rather than inferred from the machine name.
Nearest EP-SCS Bore Options
EP-SCS25 is centered on a 25 mm shaft interface. Nearby catalogue entries such as EP-SCS22 and EP-SCS20 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 45 mm OD and 12 mm width as separate envelope checks.
RFQ Focus for EP-SCS25
Send the shaft measurement, quantity, component spacing and any keyway requirement. If K = 8 mm is part of the request, include mating key information so the keyed interface can be reviewed as a system.
For EP-SCS25, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 25 mm shaft dimension, quantity and any restricted 45 mm OD / 12 mm width envelope so the quotation addresses the real assembly.
