Figure 2 DualVee Motion Technology (left) vs. alternative recirculating bearing technologies (right).
ƒ Recirculating elements in DualVee guide wheels are self-contained and isolated from the environment; rolling contact between wheel and track sweeps debris aside making DualVee ideal for use in contaminated environments.
ƒ Alternative round and square rail linear guides have recirculating elements directly in contact with the rail’s bearing surface, making shielding of the ball path region difficult. These alternative bearing technologies often require bellows or other costly methods of protection to prevent the ingress of contaminants which leads to failure.
