 Development Background Electronic device mounting machines, semiconductor- and LCD-conveyance equipment, medical devices, and equipment for food products and related packaging are used in clean environments, and as such, require features that prevent grease from splattering. In recent years there has been an increase in grease splattering due to the increase in the rotation speed of ball screws driven by the demand for shorter production times. In response to this, NSK has developed a ball screw that minimizes grease splatter thanks to an L1 seal, which reduces the amount of grease splattered without increasing friction loss. Product Features 1. Dramatic reduction in grease splatter The newly developed L1 seal is a non-contact seal that employs a structure that prevents grease from accumulating on the screw shaft surface, which in turn reduces the amount of grease splattered without increasing friction loss. This newly developed seal reduces the amount of grease splattered by ball screws to 1/10th that of NSK's previous product. 2. Standard seal cover A cover designed to cover the outer circumference of the seal comes standard. This prevents grease that has pooled up in the circumference of the seal from dripping, delivering an even cleaner result. 3. Can be applied to existing standard inventory ball screws
