Gresham Gas Sampling products

Spherical bearings are typically mounted inside a yoke, which is attached to the test article or test frame. FOX-VPS offer two ranges of bearing yokes, which can be attached to either test articles or machine bed-plates. Both types are fatigue rated and are provided with hardened ground pins and mounting bolts.

Commercially available spherical bearings typically offer around 7 degrees of rotational freedom in 2 axes, which is sometimes insufficient for certain types of test. Designed to fit in place of a standard spherical eye end FOX-VPS have devised a spherical ball end joint, complete with backlash adjustment, which provides up to 20 degrees of rotational freedom. Manufactured from high strength alloy steel and coated with a low friction, hard wearing bearing material, these devices can be interchanged with existing DIN648 style eye ends and actuator mounts to provide increased flexibility in the test laboratory.

For applications that require low rotational friction levels during testing, FOX-VPS manufacture a range of Cardan Joints that virtually eliminate lateral forces and moments when rotating under load. Designed to provide +/-8 degrees of rotation about the in plane axis these bearings are fatigue rated and backlash free and are sized to suit FOX-VPS ranges of Hydraulic Test Actuators.
