Gonio bearings RGBF series

Compact cross roller Gonio Bearings engineered for high-accuracy angular positioning in optical, metrology and semiconductor applications. Each set provides defined curvature geometry, the rotation axis remains constant throughout the travel range, preventing offset or parasitic movement. All components are matched per set and precision-ground. Factory measured parallelism and curvature guarantee sub-micron accuracy of motion. After preload they guarantee high repeatable accuracy of motion and consistent low friction resistance.

For dynamic or vertical applications, an optional Anti-Cage Creep (ACC) system prevents roller cage displacement during oscillating motion.

Features

A set of gonio bearings consists of four precision-ground curved rails, two crossed roller cages and eight end screws and plates preventing the cage for running out. The set is delivered with transport locks which make the assembly easier. These locks need to be removed after assembly.

Gonio bearing set with transport locks
1

Flat design feature on all four rails enables simple and cost-effective machined assembly surfaces of support structure (slide top and slide bed).

2

Through-hardened and precision ground stainless steel rails, material 1.4034.

3

Stroke range is ± 5 degrees or ± 10 degrees depending on type.

4

The rail mounting holes are both threaded and countersunk so that either standard screws or the next smaller screw size can be used in combination with threaded holes in the user's components.

5

Transport locks to be removed after final assembly.
