More Information
• Keyless - Locking by Friction:
Allows high-accuracy mounting with no backlash.
Easy phase matching.
Omission of keyway machining 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 also. (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.
