Ball screw cylindrical single nut ZEM-E-S 12x10Rx2-2 - Bosch Rexroth R153249022

On a ball screw assembly with a nominal screw diameter of 12 mm and a 10 mm lead (right-hand), this cylindrical single nut ZEM-E-S is the driven nut: every turn of the screw moves the attached machine part by 10 mm, with a dynamic load capacity of 3000 N. The cylindrical body is fitted into a holder, for example the aluminium nut housing MGA intended for ZEM-E-S, ZEM-E-K and ZEM-E-A nuts.

As part of the miniature series it suits compact axes with little installation space. Permissible values are up to 60 m/min linear speed and operating temperatures from -10 °C to +80 °C.

Benefits

• Load capacities: dynamic C = 3000 N, static C0 = 3600 N (valid for tolerance grade T5)
• 10 mm lead, right-hand: 10 mm travel per screw revolution
• 2 ball track turns with 2 mm balls
• Standard seal fitted at the factory keeps dirt off the ball track
• Matches the MGA nut housing made of aluminium
• Linear speed up to 60 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 10R x 2 - 2. 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.
