Features□ Model numbers of P series●―――Developed―by―drawing―upon―KURODA’s―technical―expertise―in―
manufacturing―high―accuracy―ball―screws• Screw shafts are manufactured according to the same degree of lead accuracy used for ballscrews and have achieved high precision positioning.

●―――Utilizing―materials―with―excellent―chemical―and―corrosion―resistance• Screw shafts can also be selected in stainless steel that has excellent corrosion resistance.
• For nuts, resin with excellent chemical resistance is employed.

●―――Lightweight―resin―lead―screws―with―longer―service―life―have―been―achieved• With the introduction of resin components, the PY/PW series screws can contribute to thelightweight requirements of tabletop applications.
