Properly align the reference mounting surface B and D1 or D2 of the track railand slide unit with the reference mounting surface of the table and bed, and fix
them in place.
The reference mounting surfaces B and D1, and D2 and mounting surfaces A andC are precisely ground. Machining the mating mounting surface (of the machine,device, etc.) to a high degree of accuracy and mounting them properly will ensurestable linear motion with high accuracy.
The track rail reference mounting surface B is identified by the mark on the top
surface of the track rail. It is the side surface above the mark (in the direction ofthe arrow).
The reference mounting surface of the slide unit is located at both right and leftsides (D1 and D2).
It is recommended to add a shoulder to the mating reference mounting surface
as shown in the figure to the right. The shoulder height of the track rail should be
set to a position (height) where it does not interfere with the slide unit.
The recommended screw tightening torque when mounting the product to a steel
mating member material is shown in the table below.
It is recommended to use a tightening torque of 70 to 80% of the value in thetable for slide unit mounting holes.

Example1■ Mounting methods

Note (1)	The dimensions of track rail are described in Table 1.
(2)	Track rail mounting bolts are not appended.
(3)	The directional values for basic dynamic load rating (C ), basic static load rating (C0 ), and static moment rating (T0, TX, TY ) are shown in
the figures below.
The upper values of TX and TY are for one slide unit, and the lower values are for two slide units in close contact.
(4)	Concerning screw length □ , prepare the screws whose fixing thread depth is less than the track rail height dimension.
Remarks (1) Balls are not retained. No end seal is attached.
(2) No oil hole is prepared. For re-greasing, apply the grease directly to the raceway of the track rail.
