Ball screw zero-clearance adjustable single nut SEM-E-S 12x5Rx2-3 - Bosch Rexroth R153246024

On a ball screw assembly with a nominal screw diameter of 12 mm and a 5 mm lead (right-hand), this zero-clearance adjustable single nut SEM-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. It is supplied with standard axial clearance; as an adjustable design, the clearance can be set to zero during assembly. The matching housing is the MGS steel 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.
