Ball screw single nut with flange FEM-E-B 40x5Rx3.5-5 - Bosch Rexroth R150241084

On a ball screw assembly with a nominal screw diameter of 40 mm and a 5 mm lead (right-hand), this single nut with flange FEM-E-B is the driven nut: every turn of the screw moves the attached machine part by 5 mm, with a dynamic load capacity of 34900 N. The flange with hole pattern BB1 bolts directly to the carriage or into an MGD steel nut housing.

It belongs to the Bosch Rexroth standard series. Permissible values are up to 19 m/min linear speed and operating temperatures from -10 °C to +80 °C.

Benefits

• Load capacities: dynamic C = 34900 N, static C0 = 64100 N (valid for tolerance grades T3 and T5)
• 5 mm lead, right-hand: 5 mm travel per screw revolution
• 5 ball track turns with 3.5 mm balls
• Standard seal fitted at the factory keeps dirt off the ball track
• Hole pattern BB1, matches the MGD nut housing
• Linear speed up to 19 m/min, operation from -10 °C to +80 °C

Installation note

The nut only runs on a screw of the same nominal size 40 x 5R x 3.5 - 5. 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.
