Common End Support Configurations

Each standard size is available in nine mounting/bearing combinations to provide the end support needed to meet the load carrying capacity, speed, stiffness, and design life objectives of the operating system. For the four most common end support configurations (Rigid-Free, Simple-Simple, Rigid-Simple, Rigid-Rigid).

EMBS rigid free

Rigid Free

One end of the screw is fixed by a “C” type bearing block with spaced angular contact bearings to prevent radial and axial movement. The other end is not supported.

EMBS simple simple

Simple-Simple

Each end is supported by either an “A” type bearing block for radial support, or a “B” type bearing block for radial and axial support.

EMBS rigid simple

Rigid Simple

One end is fixed by a “C” type bearing block. The other end is supported by an “A” type bearing block for radial support, or a “B” type bearing block for radial and axial support.

EMBS rigid rigid

Rigid Rigid

Both ends are fixed by “C” type bearing blocks for maximum ballscrew assembly stiffness and to prevent radial and axial movement.
