The NB SLIDE GUIDE SEB type is a profile miniature linear rail guide system in which the ball elements roll along two raceway grooves. This is the smallest and lightest slide guide series offered by Nippon Bearing. The compact design allows for the size and weight of machinery and other equipment to be reduced.
Miniature Linear Guides – SEB Type
As experts in linear bearing guides, the engineers at NB created a comprehensive range of linear rails and bearings to cover the widest spectrum of the market and all types of industry. Our line also includes miniature linear bearings, ideal for when you want to reduce the size of your machinery while adding increased movement and capability into the space you have available.
NB offers the advanced design and construction required for your smallest, most precise equipment and machinery. Our SEB Type Slide Guide series has all the features you need in an extremely compact yet high-performance size.
Reduced Size, Increased Functionality
Reducing the size of linear guides and bearings creates a particular challenge: We need to maintain movement and position precision, load-bearing capability and longevity in a compact package that allows you to downsize your machinery and equipment. Our NB Slide Guide SEB miniature linear bearings are the answer.
The low profile and narrow width of the block requires minimal space for operation, but still provide all of the critical features you require, such as:
thanks to our two-row, four-point contact design that also permits an extremely low overall height.
The ability to remove the block from the guide rail
thanks to integrated ball retainers that facilitate installation and maintenance.
Full stainless-steel construction
in our SEBS-BM type miniature linear bearings, which is ideal for high-temperature and clean room applications.
Resistance to deformation during assembly
thanks to an AD profile on our guide blocks that dissipates installation forces.
With the full-size features we incorporated into our miniature linear bearing products, you can meet your original design criteria and small-space requirements. This reduction in your linear guide envelope has the positive effect of smaller space and lighter weight, which can translate to faster, more efficient machine design and operation.
Designed for Compact Size
You’ll appreciate that we manufactured the main body, return caps and ball elements to exacting tolerances for a perfect fit. The result is an industry-leading miniature linear bearing design for your smallest and most precise equipment. Our compact NB Slide Guide SEB series is especially suitable for optical and measurement systems in which every fraction of an inch is counted and smooth, accurate movement is critical.
NB Slide Guide SEB Series miniature linear guides offer you the design flexibility and function required to measurably downsize your equipment and machinery.

You can also download all of our 2D and 3D CAD models for easier design and integration.
The SEB type SLIDE GUIDE consists of a rail with precisely machined raceway grooves and a block assembly consisting of the main body, return caps and ball elements.
A wide block (WB/WA) type, a long block (BY/AY) type, and a wide/long block (WBY/WAY) type are moment resistant slide guide types. The most suitable type can be selected for any demanding operating condition.
All Stainless Steel Type
By using stainless steel for the return caps, the SEBS-BM type is made of all stainless steel components, making it the ideal choice for special environments such as high temperature, clean room, or vacuum applications.
Because of the ball retainers, the SEBS-B type is able to be removed from the guide rail, simplifying its installation and resulting in lower assembly costs.
Tapped Hole Rail Type
For the SEB rails, counterbore (standard) and optional tapped hole (N) types are available enabling various installation methods.
AD profile dissipates guide block deformation caused by installation.
SEB type has a 2-row, 4-point contact structure. This structure minimizes the installation height, which contributes to light-weight and miniaturization of machinery and equipment.
- The SEB(S) type slide guides are categorized according to their block shape and the rail installation method.
