Fixed bearing LAF-C-A 35 for ball screw 48 x 5/10/20 - Bosch Rexroth R159A33501

At the screw end of a ball screw assembly in size 48 x 5/10/20, this bearing absorbs the axial forces of the screw and locates it lengthwise. The LAF-C-A 35 offers a dynamic load capacity of 66000 N and a static load capacity of 177000 N; the limiting speed with grease lubrication is 2000 min⁻¹.

The unit comprises: angular-contact thrust ball bearing LGF (not available individually), slotted nut NMA. It fits screw ends of type 812, 822.

Benefits

• Dynamic load capacity C = 66000 N, static load capacity C0 = 177000 N
• Axial bearing rigidity RFB 1600 N/μm
• Tilting rigidity Rkl 900 Nm/mrad
• Limiting speed with grease 2000 min⁻¹
• Frictional torque with seal 0.9 Nm
• Outer diameter D 90 mm for the mounting bore

Installation note

A floating bearing is fitted at the opposite screw end to take up the thermal expansion of the screw.
