50 mm machine-tooling and robust fixture layouts
EP-SCS50 is a single-split aluminum shaft clamp with a 50 mm nominal bore, 85 mm outside diameter, 22 mm width and M10 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-SCS50 Fits Best
EP-SCS50 uses a 50 mm bore, 85 mm outside diameter, 22 mm body width and M10 clamp screw. This size is appropriate to evaluate for substantial machinery and fixture shafts where space and service access have already been designed around a larger collar envelope.
EP-SCS50 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 85 mm outside diameter and 22 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-SCS50 | 50 mm | 85 mm | 22 mm | M10 | 3 mm | 14 mm |
Selection starts with the measured shaft diameter, then moves to the surrounding envelope. Confirm the 85 mm outside diameter, 22 mm axial width and access to the M10 screw against the real assembly before treating EP-SCS50 as a replacement or new-build fit.
Interface Review
Do not select this model from the shaft diameter alone if the existing machine has a shoulder, bearing locknut or other axial-retention feature nearby. Compare the full assembly so the collar does not conflict with those components.
The EP-SCS chart lists K = 14 mm for the keyed option on EP-SCS50, 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-SCS50 can serve as a removable stop on a 50 mm guide shaft, an axial reference beside another shaft-mounted component, or one side of a paired locating arrangement. Its 22 mm body width and 85 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-SCS50 is intended to act as a hard stop rather than a setup reference, describe the contact event in the enquiry. Repeated impact on a 50 mm shaft creates a different selection question from occasional positioning, even though the listed collar dimensions are unchanged.
Installation and Service Considerations
For a maintenance replacement, inspect the shaft surface where the old collar sat. Wear, fretting or coating buildup can affect the measured diameter and may signal that the application deserves more review than a simple like-for-like part swap.
For the larger EP-SCS50 interface, reserve working space around the M10 screw as well as the full 85 mm radial envelope and 22 mm body width. If the 50 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-SCS50 body is tightened through its M10 clamp screw and the listed split W is 3 mm. Install it on a clean 50 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-SCS50. 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-SCS50 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 85 mm × 22 mm envelope can be checked against the installation rather than inferred from the machine name.
Nearest EP-SCS Bore Options
EP-SCS50 is centered on a 50 mm shaft interface. Nearby catalogue entries such as EP-SCS45 and EP-SCS40 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 85 mm OD and 22 mm width as separate envelope checks.
RFQ Focus for EP-SCS50
Provide measured shaft condition, quantity, available 85 mm OD envelope and any keyed-interface details. A photo plus a few marked dimensions usually gives more useful information than an equipment model number by itself.
For EP-SCS50, identify whether the collar will be a fixed stop, adjustable setup reference, paired locator or keyed interface. Include that role with the 50 mm shaft dimension, quantity and any restricted 85 mm OD / 22 mm width envelope so the quotation addresses the real assembly.
