Summary description ball screws Due to their premium quality and precision, the rolled Carry ball screws are suitable for all linear applications where heavy loads need to be transferred with optimum medium moving speeds high-helix ball screws The cold-rolled, wear-resistant Carry Speed- line are marked by an extremely high helix. They provide for high moving speeds and deliver an efficiency which is nothing short high moving speeds high-helix lead screws The Speedy high-helix lead screws with he- lix up to 6 x diameter provide for maximum moving speeds at low rotational speeds or efficient...

Carry type «ZYI» Cylindrical single nut with single-thread ball return Legend d0 = nominal screw diameter [mm] d1 = outside screw diameter [mm] d2 = core diameter [mm] p = pitch [mm] i = number of ball circulations [–] = DW ball diameter [mm] S = lubrication hole (position not defined) [mm] SA = wipers F = felt rings (on request; in case of lifetime lubrication) T = standard backlash [mm] 3) Warning! Note when selecting a ball screw that the maximum rotational speed depends on the system’s rotational speed characteristics. See page 39 for the appropriate calculations. Special designs...
