1. No Need to Machine Keyways
No keyway machining required, round shafts and holes can be used as is.
Reduces cutting and processing time, enabling fast response to urgent design changes.

2. Easy to Install and Detach
Connected only by bolts for easy installation and disassembly.
Key separation method
- You must use a dedicated tool (pulley) when separating the key
- Additionally, once separated, the shaft and hub can
- Cannot be reused
Mechalock separation method
- Use a standard wrench for separation
- Can be reused after separation
No special tools are required, and equipment maintenance is simple.
Parts can be reused, reducing costs.

3. Position Alignment is Flexible
Be aligned to any position during assembly.
Fixed with a key
The position of the keyway must be specified during the design phase to align the shaft and pulley.
The pulley can be freely positioned during assembly aligned to the press-fit position.
During assembly, the position can be controlled, so there is no need to align the key and teeth positions during the design phase.

4. There is no backlash
When using a key, backlash occurs in the output, but Mecaloc has no gap. Suitable for use in places with repeated forward and reverse rotations.
Fixed with a key
Due to wear from repeated loads, A gap appears in the keyway.
Fixed by friction generated by bolt tightening force, so no backlash occurs.
Long-term high concentricity precision fastening is possible, suitable for servo motors, etc.
Suitable for use in places with repeated forward and reverse rotations.

General Mounting
Pulley / Sprocket
These are the main applications of the Mecha-Lock. Simple mounting and removal improve equipment maintenance efficiency.

Position Adjustment
Crank / Cam mechanism
The alignment position can be controlled during assembly, reducing design effort.

Load bearing
Index table
Can withstand axial loads, suitable for heavy load areas.
Others
Coupling
With no backlash, the Mecha-Lock achieves high coaxial precision can also be used as a coupling.
