Guide Ball Bush LG - 2

Since model LG has 4 rows of circular arc grooves (raceways), it does not need a mechanism to prevent the outer tube from rotating. In addition, its load rating is much larger than Linear Bushing model LM with the same dimensions. Therefore, replacing the Linear Bushing with the Guide Ball Bushing will reduce the size and cost of the guide unit and extend the service life. # Higher load rating than the Linear Bushing Since model LG ensures an R contact through the use of circular arc grooves for ball contact, it achieves a load rating more than twice that of point-contact Linear Bushing...

To mount model LG, use a pin hole machined on the LG nut. As with the conventional Linear Bushing, model LG can be mounted using snap rings and/ •Mounting model LG using a pin •Mounting model LG as with the conventional Linear Bushing Snap rings Stopper plates Q Precautions To Be Taken if an Eccentric Load Is Applied Model LG achieves a much higher load-carrying capacity in receiving the eccentric load (moment and torque) than Linear Bushing model LM because of 4 rows of raceways. However, under conditions where the eccentric load is larger, the product may result in poor operation or early...

Examples of Changing the Linear Bushing to the Guide Ball Bushing Advantage of using the Guide Ball Bushing 1 : Longer service life Since model LG has a rated load more than 2.4 times the Linear Bushing with the same dimensions, replacing the Linear Bushing with model LG will increase the service life by more than 13.8 times. Comparison of the service life between Guide Ball Bushing mode LG and Linear Bushing model LM Advantage of using the Guide Ball Bushing 2: Smaller machine size Since the Linear Bushing is not suitable for applications where a load in the rotational direction is...

TfiHlK Guide Ball Bushing LG Assembling the LG nut with the LG shaft • When assembling the LG nut with the LG shaft, match the positions of balls inside the LG nut with the grooves on the LG shaft, and then insert the LG shaft into the LG nut straight and gradually. If the LG shaft is not inserted straight, balls may fall out or the circulating part may be damaged. • If the LG shaft sticks while you are inserting it, do not force it into the nut, but pull it out first, re-check the positions of the balls with the positions of the LG shaft grooves, and then re-insert the shaft straight and...
