GGB
yi gong
GGB is the earliest developed LM guide and is one of the widely used guides. Design with equal 45o contact angle, which makes equal load in vertical upside ,vertical downside, horizontal left and horizontal right four orientations(see fig-1), and it has heavy rated load, good rigidity, high stiffness and strong torque resistance of three directions, so it also calls four direction equal load LM guide.
