Specifications/Overview
■ Product Details
○ 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 as well.
(15 to 20% less allowable torque)
■ Precautions for Use
○ Tightening torque control is required.
(A torque wrench is recommended)
○ Replace the fluororesin tape (seal tape thickness: 0.1 mm) on the threads for reuse.
○ Use shafts with h7 tolerance / 8S surface roughness or better.
○ Shaft Insertion Depth Standard a1 (in the table) is recommended.
Minimum a2 is required.
○ Only for CPNS d = 30 and 35, a special coating (black) to prevent galling is applied to nuts.
