Part Number Definition Series ED
Example of part number definition: ED 513X/V501X
ED 513X/V501X = ball nut. (EDD = two ball nuts)
ED 513X/V501X = 4 x pitch of ball nut thread
ED 513X/V501X = outer diameter of ball nut
ED 513X/V501X = ball nut in stainless steel material
ED 513X/V501X = ground precision screw
ED 513X/V501X = 4 x pitch of screw thread
ED 513X/V501X = screw drawing number
ED 513X/V501X = screw in stainless steel material
