The ball chain type linear guideway, SMG series, equip with the patent of ball chain design can make the movement smooth and stability, especially suit for the requests of high speed, high accuracy. The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life, and reliability.
1.The Optimization Design of Four Directional Load
Through the structure stress analysis, SME series have four trains of balls are designed to a circular contact angle of 45° and the section design for high rigidity. Except for bearing heavier loads in radial, reversed radial and lateral directions, a sufficient preload can be achieved to increase rigidity, and this makes it suitable for any kind of installation.
2.Self Alignment Capability
The self adjustment is performed spontaneously as the design of face-face (DF) circular arc groove. Therefore, the installation error could be compensated even under a preload, and which results in precise and smooth linear motion.
3.Ball Chain Design, Smooth Movement
The concise and smooth design of circulating system with strengthened synthetic resin accessories and cooperating with the ball chain, these can avoid interference between balls and make the balls more stability during passing in and out the load district. Besides, the ball chain can keep the ball move in a line and improve the
movement most smooth substantially.
4.Low Noise, Good Lubricant Effect
The ball chain design avoids collision, lowers the operating noise and effectively provide the lubricant of balls and chains. The superior effect of lubrication improves the overall device’s movement and service life, also meets high precision, high reliability and smooth & stable movement requirement.
5.Wide rail and compact design
The width of rail is expanded and the height of linear guide is reduced.Under the environment of high torque or limited space application, PMI offers you the installation of one-axial structure to replace double axial structure.It can save the time of assembly and adjustment.( As show as below)
