Low profile basic

Low profile slide assemblies are useful

for a broad range of applications where
the load induced into the assembly
is moderate and a compact design is
essential.
Basic slide assemblies consist of a saddle,
base, gib and gib adjusting screws. They are
designed for installations where the means of
movement, mounting, and all other details are
provided by the customer.
Way surfaces can be supplied either milled
or scraped.

High profile basic

High profile slide assemblies are useful

for a broad range of applications where
the nature of the work to be done
requires a more rugged construction than
the “L” section slide assemblies. Greater
stability and capacity are accomplished
by increasing the thickness of the saddle
and base. The increased height of the
saddle also allows greater flexibility for
machining mounting requirements.
Basic slide assemblies consist of a saddle,
base, gib and gib adjusting screws. They are
designed for installations where the means of

Dovetail slide basic

“DC” slide assemblies are versatile

because of their availability in one-inch

This means the designer can use a slide

often resulting in a savings of cost and
