Bearing for screw drives

Bearings for screw drives are designed for special requirements that conventional rolling bearings cannot optimally meet due to their structural design. Bearings for screw drives are high-performance combined bearing units that combine the properties of sliding bearings in one component and therefore represent an extremely economical solution and meet technical requirements with the highest precision.

Axial angular contact ball bearing

  • ready-to-assemble unit
  • one, two or three row bearing unit
  • self-retaining
  • dimensionally stable, thick-walled outer rings
  • depending on the series, they absorb radial and one- or two-sided axial forces

Needle axial cylindrical roller bearing

  • double-direction axial cylindrical roller bearing with radial needle bearing*
  • high axial runout accuracy*
  • high rigidity*
* depends on type
