Fixed bearing LAF-B-A 17 for ball screw 25 x 5/10/25, 16 x 5/10/16 - Bosch Rexroth R159001730

At the screw end of a ball screw assembly in size 25 x 5/10/25, 16 x 5/10/16, this bearing absorbs the axial forces of the screw and locates it lengthwise. The LAF-B-A 17 offers a dynamic load capacity of 18800 N and a static load capacity of 31000 N; the limiting speed with grease lubrication is 3300 min⁻¹.

The unit comprises: angular-contact thrust ball bearing LGF, slotted nut NMA or NMZ. It fits screw ends of type 51, 51A, 52, 52A, 81, 81A, 82, 82A, 91, 91A, 92, 92A.

Benefits

• Dynamic load capacity C = 18800 N, static load capacity C0 = 31000 N
• Axial bearing rigidity RFB 450 N/μm
• Tilting rigidity Rkl 80 Nm/mrad
• Limiting speed with grease 3300 min⁻¹
• Frictional torque with seal 0.24 Nm
