The LWH series of interchangeable linear guides are lateral movement guides with a high load capacity of
which the stroke-length is limited only by the length of the guide rails. The dimensional accuracy of both the
slides and the rails is controlled 100% during manufacture to ensure interchangeability and all components
can therefore be added or replaced freely.
The conception of a double track, use of large diameter steel balls in 4 point contact with the rail not only
provide a accurate and repeated linear movement, but also high rigidity, even under combined or variable
loads.

Parallelism deviation (mm)
Note (1): This is the difference in the dimension H between two slides mounted on the same track or on a pair
of tracks when H is measured at a specified position.
Note (2): This is the difference in the dimension N between two slides mounted on the same track or on a pair
of tracks when N is measured at a specified position.
Note (3): These values also apply when the reference surfaces are assembled opposite each other.
Note (4): The difference in the dimension H for multiple assemblies represents the dimensional variation
between the slides of an arbitrary number of assemblies having the same accuracy class.
Note: All of the above are applicable only when the dimensions are measured at the centre of the slide
mounted on a rail attached to a flat base.

.Lubrification.
These linear slides are supplied lubricated with a Lithium soap based grease (Class 2) containing extreme
pressure additives. A stoppered grease injector is supplied with each slide, this should be attached before use.
.Assembly.
To assemble LWH linear slides, correctly position the assembly reference surfaces of the slide and rail on the
reference surfaces of the table or frame and fasten securely.
.Reference mounting surface.
The reference side of the slide is the opposite side to the surface carrying the manufacturer’s logo.
In the same way, the reference side of the rail is that one opposite the upper surface which is marked with
the manufacturer’s logo.

.Assembly recommendations.
1- Manipulation
Every slide is supplied mounted on a dummy rail. When assembling the slide onto its guide rail,
align the slots of the dummy rail with the guide rail and then move the slide on to the guide rail
keeping the parts aligned correctly.
fw : load factor (see table 1)
Fc : calculated theoretical load, N
2- Multiple slides mounted side by side
Every slide is supplied mounted on a dummy rail. When assembling the slide onto its guide rail,
align the slots of the dummy rail with the guide rail and then move the slide on to the guide rail
keeping the parts aligned correctly.
3- Example of multiple slide units mounted close together
Referring to Figure 3, the reference mounting surfaces B and D and mounting surfaces A and C of the LWH
linear slides have an accurately ground finish. Stable and high accurate linear motion will be obtained
by finishing the mounting surfaces of machines or equipment to the same high accuracy and correctly
mounting the guides on these surfaces.
It is recommended to machine a fillet at the corner of the mating reference mounting surfaces as shown
in Fig. 4 . However, a radius smaller than R1 of the slide or smaller than R2 of the rail( see table 1) is also
possible.
The heights of flanges on assembly reference surfaces are also given in table 1.
