Product Description

The NB experts spent years studying and researching industry requirements for linear crossed roller guides in miniature guide profile. The result is our SER series of slides, combining compact size, high load capacity, and design and installation flexibility.

Applying the same top-quality materials and precision machining that go into all of our linear movement solutions, we offer some of the best roller bearing slides in the world. You can use them in a wide range of applications, including demanding environments, such as high-temperature, clean room and vacuum situations.

Precision by Design

You’ll appreciate the fact that we manufacture all of our SER type Slide Guide rails with precision-machined raceway grooves. Our fully metallic block main body and rollers are precision components that contribute to the high load capacity and long life of our linear roller guides.
By using roller elements, we spread the load over a large contact surface. With our design, you can use a single guide, which further reduces the space requirement and supports decreased machine size.
Our NB Slide Guide SER series also feature many other intelligent and useful features, such as:
N-type rails with tapped holes or standard rails with counter bore holes.
Multiple grades of steel, depending on your required corrosion resistance.
Crossed rollers placed in two rows that use a recirculating motion for high rigidity.

Thanks to these advanced features of our SER roller bearing slide products, you can design with greater flexibility. The result is reliable linear movement for your machines and equipment that translates into increased efficiency.

Function and Flexibility

With our NB Slide Guide SER series of linear roller guides, we brought together the best in function and flexibility. All-metallic construction makes our roller bearing slides adequate in your most demanding applications, such as clean rooms, corrosive environments and high-temperature situations. The roller design results in minimal wear and extended service life, which is critical in decreasing your downtime and increasing your throughput.

Our NB Slide Guide SER meets the needs for high-quality linear roller bearing slides. All of our NB Slide Guide SER CAD files are available for download, both in 2D and 3D format. Consult our catalog of linear roller guides and use our CAD files to begin integration into all of your machinery for the optimum mix of high performance and compact size.

Structure and Advantages

The SER type SLIDE GUIDE consists of a rail with two precision-machined raceway grooves and a block assembly. The block assembly consists of the main body, rollers, and bottom retainers. All of these components are made of metallic materials.

High Load Capacity and Long Life

Since roller elements are used, the contact surface is large which provides a high load capacity and a long travel life.

Moment Resistant Type

The wide block design (WA type) has an extremely high moment loading capacity. This will allow for single guide designs in the most demanding and compact applications.


Since a cross roller method is utilized, only two raceway grooves are necessary and presents a very compact package.

Tapped Hole Rail Type

For the SER rails, counterbore (standard) and optional tapped hole (N) types are available enabling various installation methods.

All Stainless Steel Type

The SERS type slide guide is made of all stainless steel components, making it ideal for high temperature, clean room or vacuum applications.

Structure of SER type SLIDE GUIDE

The SER type SLIDE GUIDE is available with a standard block or a wide block (WA) configuration. Each type can be selected with standard rails of counterbore holes or the optional N-Type rails of tapped holes. For anti-corrosion, all stainless steel type is also available with all stainless steel components.
