20mm Ø x 5mm lead x 1500mm length rolled ball screw assembly

Don't let the low prices fool you...these are high-quality screws!
Precision rolled ball screw assembly with machined ends

• C7 accuracy grade
• 20mm diameter, 5mm lead
  
• Overall length of assembly:  1500mm
  
• Stroke/travel:  ~1376mm
  (We determine travel by subtracting the machining measures at both ends plus length of ball nut from the overall length of the screw.)
  
• Ball nuts are the "oversize ball" type rated as "anti-backlash." Anti-backlash is defined as <0.015mm or <0.0006". Nuts also come standard with flanges. Our ball nuts are individually loaded and matched to the screw for optimum performance.
• Lead error not to exceed +/- 0.050mm/300mm or 0.002"/12".
• Ball nuts supplied with zerk-type grease fitting.
• End machining has already been performed for the BK or FK (fixed) type mount on the drive end and BF or FF (simple) type mount on the floating end of the unit. Mounts available below as an option.
  
• We attempt to keep all sizes of ball screws and end supports in stock for immediate availability.
• Custom ball screws in just about any diameter and lead can be supplied in a reasonable time frame (usually 2 to 3 weeks). Go to our "Help" page to tell us about your requirement and to initiate a quote.
