Long lead rolled ball screws SL / TL

Long lead rolled ball screws SL /TL
Specifically designed for applications requiring high linear speed for increased productivity, the SKF range of long lead ball screws combines precision rolling technology and recirculation through nut end caps. Thanks to the precision ground nut outside diameter and flange face, this design fits most positioning applications. For further positioning accuracy, SKF offers this range with backlash elimination.

Features and benefits

  • Lubrication hole for grease nipple or for SKF SYSTEM 24 automatic lubrication kit
  • Standard protection at each end of the nut with composite wipers integrated into recirculation caps (NOWPR)
  • Optional double protection at each end of the nut with additional brush wipers fitted into recirculation caps (WPR)
  • Optional surface coating on shaft and nut
  • Optional safety nuts. Please contact SKF
  • Optional support bearings
  • High rotational speed up to nd0 = 90 000, resulting in high linear speed up to 110 m/min
  • Nut design well suited for transport or positioning screw applications requiring high velocity such as woodworking, some functions in plastic injection presses, pick and place etc.
