SLIDE GUIDE
GREASE FITTING
HIGH LOAD CAPACITY AND LONG LIFE
A grease fitting is attached to the return cap of SGL type and GL type guide blocks for lubrication purposes.
Unless otherwise specified, the orientation of the grease fitting is as shown in Figure A-57. When more than
2 blocks are used on one rail, please specify the grease fitting orientation.
Figure A-57 Grease Fitting Orientation
The GL type slide guide has a load rating of 1.2 to 1.6 times greater than the load rating of other branded
"low-noise" type guides. This high load capacity enables a longer travel life.

CLEAN OPERATIOIN
NB mark side
Ball cushions eliminate metal contact between the steel balls and prevent excess grease spatter, enabling
linear operation with low levels of dust generation.
