Accuracy grade of BBS series(standard cold rolled stainless steel ball screw are based on C5,Ct7 and Ct10(JIS B 1192-3).According to accuracy grade, Axial play 0.005(Preload :C5),0.02mm(Ct7) and 0.05mm or less(Ct10).
BBS series (standard cold rolled stainless steel ball screws), the screw shaft screw material is SUS440C (induction hardening), the nut material is SUS440 (vacuum hardening), and the surface hardness of the ball screw part is HRC55 or higher.
The shape of the shaft end of the BBS series (standard stainless steel cold-rolled ball screws) has been standardized.And has been kept delivered in time all the year round. Screw rod and nut can be ordered separately.
