Reach Self-Centering Locking Assembly Type 02, 8 x 15 mm - REACH02-8
Available
The Reach Type 02 locking assembly is a keyless shaft-to-hub connection for shaft diameters from 8 to 150 mm. It is self-centering.
Tightening the locking screws converts the clamp load into radial contact pressure on both the shaft and the bore of the mounted component. The result is a zero-backlash interference fit that takes torque, thrust, bending and radial loads, with no keyway or grub screws needed.
Where this product is used
- Mounting sprockets, pulleys, gears and couplings on shafts without a keyway
- Shaft-to-hub connections that need zero backlash
- Drives with fluctuating or reversing loads
Features
- Keyless: no keyways or grub screws required
- Zero-backlash mechanical interference fit
- Carries torque, thrust, bending and radial loads
- Pressure is distributed evenly around the shaft and hub
- Self-centering design
- DIN 912 12.9 locking screws
- 41 sizes, shaft diameters 8 to 150 mm
- Torque, axial force, pressures and screw details listed for every size

The locking screw size is shown for the smallest sizes only. For the others, contact AIMS to confirm the screw size.
Selecting the right option
Choose the size from the shaft diameter (d) and the hub bore, which matches the outside diameter (D) of the assembly. The d x D size is shown in the variant selector.
Check that the transmissible torque and axial force suit the load on the drive, and that the shaft and hub are strong enough for the contact pressures listed.
The full dimension table (L, L1, L2 and related dimensions) is on the catalogue page. It can be downloaded from the Catalogue section of this page.
Fitting and use
Fit the assembly between a clean shaft and hub bore, then tighten the locking screws to the listed tightening torque, working evenly around the assembly.
Catalogue dimensions are reference only. Contact AIMS to confirm actual measurement if a specific dimension is critical to your application.
