Ball screw single nut with flange FEM-E-S 12x5Rx2-3 - Bosch Rexroth R153246023

On a ball screw assembly with a nominal screw diameter of 12 mm and a 5 mm lead (right-hand), this single nut with flange FEM-E-S is the driven nut: every turn of the screw moves the attached machine part by 5 mm, with a dynamic load capacity of 4560 N. The flange bolts directly to the carriage or into an MGS steel nut housing.

As part of the miniature series it suits compact axes with little installation space. Permissible values are up to 30 m/min linear speed and operating temperatures from -10 °C to +80 °C.

Benefits

• Load capacities: dynamic C = 4560 N, static C0 = 5800 N (valid for tolerance grade T5)
• 5 mm lead, right-hand: 5 mm travel per screw revolution
• 3 ball track turns with 2 mm balls
• Standard seal fitted at the factory keeps dirt off the ball track
• Matches the MGS nut housing made of steel
• Linear speed up to 30 m/min, operation from -10 °C to +80 °C

Installation note

The nut only runs on a screw of the same nominal size 12 x 5R x 2 - 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.
