Miniature Ball Screws are an efficient and cost-effective solution in a small envelope, ideal for use in small spaces. Ball screw nut assembly range from 4 to 14mm in diameter with leads from 1 to 20mm - all with standard lead accuracies of ±52µm/300mm. Miniature Rolled Ball Screws are ideal for laboratory, semiconductor, and medical applications.

Ball Screw lead accuracy conforming to JIS B1192 is specified by the tolerance of actual mean travel amount, or Screw Shaft effective length, travel variation and travel variation within arbitary 1 revolution over the Screw Shaft effective lentgh. Tolerance of each accuracy grades are shown in the Table.
Nominal travel: Travel in axial direction when rotated arbitrary number of revolution according to the Nominal lead.
Specified Lead: Lead given some amout of correction to the Nominal lead in order to compensate the deformation generated due to the temperature rise or the load.
