More Information

■Details of the Product
·Keyless - Locking by Friction:
Allows high-accuracy mounting with no backlash.
Easy phase matching.
No machining for keyway contributes to total cost saving.
·High Torque Transmission / High Thrust Load Capacity:
Allows combined load of torque and thrust.
·Easy Locking with a Nut:
It is easy to mount where a space is limited. Requires no space in axial direction.
·Keywayed shafts can be used. (15 ~ 20% less allowable
torque)
■Precautions for Use
·Tightening torque control is required. (A torque wrench is
recommended.)
·Replace the fluoropolymer tape on the threads for reuse.
Use shafts with h7 tolerance and 8S or better surface roughness.
·Shaft Insertion Depth Standard a₁(in the table) is recommended.
Minimum a₂ is required.
