Ball Screw Permissible Axial Load
It is recommended that Ball Screw Shafts be used almost excclusively under tension load conditions. However, in some applications, compression loads may exist, and under such conditions it must be determined that Shaft buckling will not occur.
Also, when the mounting span distance is short, there is a restriction on the permissible tension or compression load and the Basic Static Load Rating Coa unrelated to mounting.
Buckling load, permissible tension and permissible compression load can be calculated.
Ball Screw Permissible speed
For Screw Shaft rotation, the mounting method determined the established rotation limits. When this value is approached, resonace phenomenon can occur, and operation becomes impossible. There is also rotation limit which causes damages to recirculating parts. This limit is unrelated to mounting methods.
Rotation limits for damage on reciirculating parts
Generally, regarding critical speed for damage on recirculating parts, limitation is established by dn value, which is multiplied Shaft nomial diameter of revolution, but dn value cannot be applied to Miniature Ball Screws. For our Ball Screws, please consider rotation limits by damage on recirculating parts as 3,500 to 4,000rpm. This value varies depending on operating conditions and environment. Please inquiry us for details.
