SFF [SS-CC/CF] Simplified Cleaning Compatible Type_52

This simplified cleanroom-compatible version of the SFF-model single-element coupling for servo motor drives used in feed shafts features electroless nickel plating and undergoes cleanroom cleaning, assembly, and packaging. For the clamping bolts used to secure axial force, you can choose between two types of grease: fluorinated grease and low-dust grease.

The maximum rotational speed does not take dynamic balance into account.
The torsional spring constant value refers to the value for a single element.
The moment of inertia and mass are based on the maximum bore diameter.

The designation for M1 and M2 clamp bolts is "quantity-thread size," where the quantity refers to the number of bolts on one side of the hub.
Please choose from two types of grease for clamping bolts used to secure axial force: low-dust grease or fluorinated grease.
