metric machine replacement and adjustable stops
EP-SCS22 is a single-split aluminum shaft clamp with a 22 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-SCS22 Fits Best
The 22 mm bore serves machinery that uses an intermediate shaft size between the more familiar 20 and 25 mm options. Its 45 mm outside diameter and 12 mm width should be compared carefully with the old part during a maintenance replacement.
EP-SCS22 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 22 mm bore is chosen.
Model Dimensions
| Model | Bore d | OD D | Width B | Screw M | Split W | Keyway K |
|---|---|---|---|---|---|---|
| EP-SCS22 | 22 mm | 45 mm | 12 mm | M5 | 1.5 mm | 6 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-SCS22 as a replacement or new-build fit.
Interface Review
A replacement enquiry benefits from one photo taken square to the shaft and one side view that shows the available axial space. Those images, paired with measurements, reduce the risk of selecting by bore alone.
The EP-SCS chart lists K = 6 mm for the keyed option on EP-SCS22, 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-SCS22 can serve as a removable stop on a 22 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-SCS22 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 22 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 will be moved during changeovers, keep the M5 screw accessible from the operator’s service side. That service consideration can be more important than minimizing the collar’s visual footprint.
When EP-SCS22 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 22 mm collar can be adjusted later without avoidable disassembly.
The EP-SCS22 body is tightened through its M5 clamp screw and the listed split W is 1.5 mm. Install it on a clean 22 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-SCS22. 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-SCS22 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-SCS22 is centered on a 22 mm shaft interface. Nearby catalogue entries such as EP-SCS20 and EP-SCS25 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-SCS22
Provide the measured 22 mm shaft, old collar outside diameter/width, quantity and whether a 6 mm K option is relevant. For an unidentified machine, add the photo rather than relying on the equipment brand.
For EP-SCS22, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 22 mm shaft dimension, quantity and any restricted 45 mm OD / 12 mm width envelope so the quotation addresses the real assembly.
