Compact FA Series PSS Type for General Uses

Applications

Semiconductor manufacturing equipment, LCD manufacturing equipment, material handling equipment, measuring
equipment, medical equipment etc.

Accuracy grade and axial play

Accuracy grade: C5 grade of JIS Axial play 1) Shaft dia. 6 and 8 mm: 0.005 mm or less
2) Shaft dia. 10 mm or over: 0 (Oversize ball preload)

Wide variation

Abundant combinations of shaft diameter, lead and stroke are available to meet a wide range of customer needs.

Shaft end support Support unit

The low-profile support units especially compatible with the compact
FA series are available. Since the ends of ball screw shafts are shaped
to accommodate the shapes of support units, no detailed design after
purchase is necessary.
