Ball screw single nut with flange FED-E-B 32x20Rx3.969-3x2 - Bosch Rexroth R151237032

On a ball screw assembly with a nominal screw diameter of 32 mm and a 20 mm lead (right-hand), this single nut with flange FED-E-B is the driven nut: every turn of the screw moves the attached machine part by 20 mm, with a dynamic load capacity of 38300 N. The flange with hole pattern BB2 bolts directly to the carriage or into an MGD steel nut housing.

The high-performance series is designed for high travel speeds. Permissible values are up to 94 m/min linear speed and operating temperatures from -10 °C to +80 °C.

Benefits

• Load capacities: dynamic C = 38300 N, static C0 = 67300 N (valid for tolerance grades T3 and T5)
• 20 mm lead, right-hand: 20 mm travel per screw revolution
• 6 ball track turns with 3.969 mm balls
• Standard seal fitted at the factory keeps dirt off the ball track
• Hole pattern BB2, matches the MGD nut housing
• Linear speed up to 94 m/min, operation from -10 °C to +80 °C

Installation note

The nut only runs on a screw of the same nominal size 32 x 20 R x 3.969 - 6. A complete axis also needs fixed and floating bearings for the screw ends in the matching diameter; the fixed bearing is secured with a slotted nut.
