STARLOCK vs Other Fastening Systems
Comparison with traditional alternatives
System | Assembly | Disassembly | Notes |
---|---|---|---|
STARLOCK Push-On | Fast (1 sec) | Difficult | Permanent/semi-permanent fastening |
Seeger/Circlips | Medium (pliers) | Easy (pliers) | Requires groove on shaft |
Set Screws | Slow (screwdriver) | Easy | Risk of shaft damage |
Pins/Keys | Very slow | Possible | Complex machining |
Bonding | Slow (curing) | Impossible | Permanent fastening |
Recommendation: STARLOCK ideal for fast assembly in series production. For applications requiring frequent disassembly prefer Seeger in grooves. STARLOCK is mainly for permanent or semi-permanent fastening.
