Gonio Way Guide Rails: The GSRV / GSCRV - Series

Designed for applications requiring high angular precision, stiffness and repeatability, this crossed roller gonio way series enables smooth, backlash-free arc motion around a defined center of rotation. Precision-ground raceways and crossed rollers arranged at 90° ensure uniform load distribution, high rigidity and excellent resistance to moment loads. Typical applications include optical alignment systems, metrology equipment, fine adjustment mechanisms and precision assemblies in photonics and laboratory environments.

Angular ranges
GSRV: ± 10 °
GSCRV: ± 5 ° / ± 6 ° / ± 8 °

Crossed roller design
Depending on size, featuring 7 to 14 crossed rollers for optimal load distribution and high resistance to moment loads.

Complete set delivery
Supplied as a set with 4 rails, 2 cages and 8 end screws.

GSRV

Standard ±10° gonio way configuration
Crossed roller arc guide with uniform ±10° angular range. Designed for applications requiring maximum rotation symmetry and consistent performance across the full arc movement.

GSCRV

Segmented angular range configuration
Crossed roller gonio way available with ±5°, ±6° or ±8° revolution range. Optimized for applications requiring reduced angular travel with adapted dimensional configuration.
