Your Opto-Mech products use either a ball bearing, cross roller or extended contact ball bearing design. What is the difference?
Back to FAQ The extended contact ball bearing design is similar to the ball bearing design, which is described in the link below. One limiting factor in the ball bearing design is the inability to withstand high loads. The ball bearings make contact with the rails in one single point. This limits the weight that the stage can handle because too much weight will cause irregularities in the balls and influence the motion of the stage. The advantage of the extended-contact ball bearing design is the extended curved surface in which the balls are in contact with. This extended contact between the balls and curved surface allows for a greater load capacity and higher precision than other types.
