Ground Ball Screw - Square Nut BSR0801AP3G-0120-SQS-NND-NNN-N 8mm Dia. x 1mm Lead, Length: 120mm
Ground ball screw, square nut, Grade 3, 8mm diameter, 1mm lead, 120mm length. Unlike a precision-rolled screw, whose helical thread is formed under pressure, this ball screw is finish-ground for tighter lead accuracy and repeatable positioning. The square ball nut contains recirculating balls that travel through the shaft’s helical grooves to reduce friction and convert rotary motion into linear travel. Its square body fits into a matching square pocket or housing to prevent nut rotation without requiring a mounting flange. Grade 3 is the highest accuracy class offered in the BSR line and is suited for high-precision positioning where minimal backlash and repeatable travel are critical.
