 Miniature
SER Type
The NB SER type slide guide is a linear motion bearing utilizing the rotational motion of
precision rollers placed in two rows. Despite its compact shape, it can be used in various
applications requiring high load capacity.

STRUCTURE AND ADVANTAGES

The NB SER type slide guide consists of a rail with Moment Resistant Type:
two precision-machined raceway grooves and a block The wide block design (WA Type) has an extremely
assembly. The block assembly consists of a main high moment loading capacity. This will allow for
body, rollers, and bottom roller retainers. All of these single shaft designs in the most hostile environment
components are made of metallic materials. applications.

High Load Capacity and Long Life: Rail Bolt Hole Types:
Since roller elements are used, the contact surface is SER type rails with counterbore bolt holes (standard)
large which provides a high load capacity and long and optional tapped mounting holes (N-type) are
travel life. available enabling various installation methods.

Compactness: All Stainless Steel:

Since a cross roller method is utilized, only two Since all the components for the SER type guide are
raceway grooves are necessary and presents a very made of metallic materials, stainless steel provides
compact package. excellent corrosion and thermal characteristics. The
SERS type slide guide is ideal for clean-room or
vacuum applications.

The SER(S) type slide guides are available only with a standard (0 to slightly negative) preload.

RAIL LENGTH
Slide guides with most commonly used lengths are Figure A-46 Rail
available as standard. For slide guides with a non-
standard length, unless otherwise specified, the
distance from one end of the rail to the first
installation hole (N) will be within the ranges listed in
Tables A-16 and A-17, satisfying the following
equation.

L = M

L : length (mm) N : distance from the end of the rail to the first hole (mm)
M : number of pitches P : hole pitch (mm)

MOUNTING
Mounting Surface Shapes:
Slide guides are mounted by pushing the reference surface of the rail and the block against the shoulder
provided on the mounting surface. An escape groove or a radius corner should be provided at the corner of the
shoulder, as shown in Figs.A-47 and A-48, to prevent interference. The recommended shoulder height values on
the mounting reference surface of the other component are shown in Table A-18.
