Shaft diameter of 10 to 25 mm, accuracy grades C5
High rotational speed and ultra-quiet F series ball screws achieve high rotational speed, lower sound pressure level, more compactness, and longer life without affecting the specifications, such as rated load and ball diameter, of existing products.
High rotational speed achieved by innovative recirculation system
Delivers higher rotational speed up to 5,000 min-1 based on new design and manufacturing technologies developed by KURODA.
Provides maximum table speed of 2.5 m/sec. (It is for a ball screw with a 15 mm screw shaft diameter and 30 mm lead).
Reduced sound pressure level and solved noise issue
Delivers improved sound pressure level (down by up to 6 dB) and sound quality in a high frequency range, using KURODA’s high-precision processing technologies developed during its history of gauge production and based on longstanding efforts toward quieter ball screws. (The above values are in the case of a ball screw with a 25 mm screw shaft diameter and 25 mm lead)
Nut dimensions for more compactness
With ball recirculation components provided at both end of a nut and a recirculation path developed by KURODA, substantial compactness in a overall length and outside diameter of the nut body has been realized.
Longer lifetime achieved by bigger load rating
With a load rating designed without changing a ball diameter in a KURODA’s previous model, the F series ball screw provides improved basic dynamic load rating and basic static load rating, compared with previous models.
