Ball screw single nut with flange FEM-E-B 8x2.5Rx1.588-3 - Bosch Rexroth R153223006

On a ball screw assembly with a nominal screw diameter of 8 mm and a 2.5 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 2.5 mm, with a dynamic load capacity of 2640 N. The flange bolts directly to the carriage or into an MGD steel nut housing.

As part of the miniature series it suits compact axes with little installation space. Permissible values are up to 15 m/min linear speed and operating temperatures from -10 °C to +80 °C.

Benefits

• Load capacities: dynamic C = 2640 N, static C0 = 2800 N (valid for tolerance grade T5)
• 2.5 mm lead, right-hand: 2.5 mm travel per screw revolution
• 3 ball track turns with 1.588 mm balls
• Standard seal fitted at the factory keeps dirt off the ball track
• Matches the MGD nut housing made of steel
• Linear speed up to 15 m/min, operation from -10 °C to +80 °C

Installation note

The nut only runs on a screw of the same nominal size 8 x 2.5R x 1.588 - 3. 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.
