Shaft-insertion
Features of SJC-I Series
- Easy attachment to various hub types e.g. Pulleys, Gears, Sprockets, or Hollow shafts
- Space-saving design
- Simple clamping methods by tightening a single bolt
- Self-centering function by the taper structure
- Various types of coupling hubs (e.g. Side-clamp, Set-screw) can be combined
Principles
- Bushing and Insert hub are tightly coupled by the thrust of fastening screws.
- And then the insert part gets spread outward due to the taper structure and clamped into the inner diameter on the other side.
Dimensions
Model | Coupling hub OD | Shaft-insertion hub OD |
---|---|---|
SJC-25I□ | 25mm | 10mm |
SJC□-30I□ | 30mm | 12mm |
SJC□-40I□ | 40mm | 20mm |
SJC-55I□ | 55mm | 25mm |

How to Disassemble
① Please refer to the below table.
Model | Fastening screw | Screw for disassembly |
---|---|---|
SJC-25I | M3 | M4 |
SJC-30I | M4 | M5 |
SJC-40I | M6 | M8 |
SJC-55I | M8 | M10 |
SJC-65I | M10 | M12 |
② After removing fastening screws, insert a screw for disassembly and fasten it into the tapped-hole for disassembly. And then, bushing comes out being disassembled by thrust of the screw.

Dimensions / Performance
- The Moment of Inertia and Mass values are based on products with max. Inner diameter.
- Please modify rated/max. torque value with temperature correction factor when it’s higher than 30°C.
- It’s not allowed to have other complementary options to enhance clamping force such as keyway etc. on the shaft-insertion hub. This is the reason why the above-mentioned permissible torques are based on the slip torque on the shaft-insertion hub.
- Please contact Sung-il Customer Service team for non-standard Inserted hub OD(D2) products.
- Please refer to previous pages for the standard ID range of Side-clamp hubs.
- It’s also possible to assemble with space-saving side-clamp, set-screw and taper-ring hubs.
