katalog PMI_2013 - śruby kulowe.pdfPMI’s screw mechanisms consist of a spindle and a nut with a circular thread.
The nut contains balls that move in a closed circuit. Ball screws and ball nuts are among the most commonly used screw mechanisms in industrial and precision CNC machines. They enable the change of rotary motion into progressive motion and vice versa. They are characterized by high precision and high efficiency coefficient. Rolled ball screws are an alternative to trapezoidal screws. The screw is made during the rolling process, while the nuts are made in the same way as for polished screws. Nuts without preload and with maximum axial blacklash are interchangeable, i.e. different types of nuts can be used on the same ball screw.
The range includes the following series: FSIN, FSWW, FSVW, RSVW, FSBW, SSVW, FSIW, FSDW and FSDN to DIN 69051.
Basic parameters of rolled ball screws:
- thread’s pitch: 4 – 40 mm
- thread’s diameter: 12 – 50 mm
- length: up to 6000 mm
- accuracy class: C5 – C10
- can be made with left-side thread (diameters 25 and 32 mm)
- single or double nut
