Liftmaster K11-10193, SPRING CUP
The LiftMaster K11-10193 is a replacement spring cup used in select LiftMaster commercial door operator and commercial access assemblies. A spring cup serves as the seat or support point for a spring, helping keep it centered and properly positioned as the mechanical assembly moves or applies tension. When the cup is worn, missing, or distorted, the spring may not sit correctly, which can lead to noise, uneven tension, poor alignment, or extra wear on nearby hardware. This part is not a spring by itself; it is the cup or seat used with the related spring assembly. K11-10193 is broadly listed for various LiftMaster commercial door operators and commercial access systems, so it should be confirmed by the parts diagram and the original component before ordering.

Technician Note
A worn spring cup can be a symptom of a larger mechanical problem. Inspect the spring, shaft, clutch, fasteners, and nearby linkage before putting the operator back in service.
Before Ordering Checklist
- Confirm K11-10193 or one of its related numbers appears in the parts diagram.
- Compare the cup diameter, depth, and spring seating surface to the original part.
- Inspect the spring for distortion, corrosion, or breakage.
- Check nearby moving parts for binding or abnormal wear.
- Do not reuse a damaged spring cup in a high-load assembly.
Important Ordering Warnings
- This is the spring cup only, not the spring itself.
- Exact model compatibility must be diagram-confirmed because listings are broad.
- Similar spring cups may not seat the spring at the correct height or angle.
Professional Advisory
Commercial operator spring and clutch assemblies can store force or affect operator movement. A trained commercial door or gate technician should handle repairs where spring tension or heavy moving parts are involved.
