Info

Slide guides with most commonly used lengths are available as standard. Unless otherwise specified, the distance to the first installation hole (N) from one end of the rail will be located within the range listed in Table A-37 for slide guides that have a non-standard length satisfying the following equation. L = MP + 2N RAIL LENGTH L : length (mm) N : distance to the first hole from the end of the rail (mm) M : number of pitches P : hole pitch (mm) Figure A-69 Rail MOUNTING Slide guides are generally mounted by pushing the reference surface of the rail and block against the shoulder of the mounting surface. To avoid interference between the shoulder and the corner of the rail or block, the shoulder should be fabricated with dimensions smaller than those listed in Table A- 39. The bolts used to secure the rail should be tightened to a certain torque using a torque wrench. The recommended torque values are given in Table A-38. Please adjust the torque depending on the operating conditions..

GREASE FITTING A-79 A grease fitting is attached to the SGW slide guide near the return cap for lubrication purposes. Unless otherwise specified, the orientation of the grease fitting is as shown in Figure A-71. When more than 2 blocks are used on one rail, the grease fitting orientation must be specified.
