*1：Screws must be used whithin the above-mentioned WN values is experienced as allowable load W(N) × allowable rotation speed N(min^-1)

*2：MAX. min^-1 : 1200min^-1
*3：Allowable operating temperature. -20〜60 degrees C
*4：Special paste is applied for improving initial conformability at the time of shipment.
As the paste is optionally available, please place an order if your usage conditions demand it.
*5：The accuracy is equivalent to JIS C-10 (ball screw).
