		NB SLIDE GUIDE are high-precision and high-rigidity linear bearings designed to utilize the motion of rolling elements. They have numerous advantageous characteristics including low friction, no stick/slip, and smooth linear motion even under high load conditions. Since they can maintain their high-efficiency and high-functionality characteristics for an extended period of time, they meet a wide range of needs, from general industrial to precision machinery.




Outline of SLIDE GUIDE

Five different types of slide guides, each with differing structures are available for your selection. ("SEBS-B type" is structurally the same as the SEB-B type, however all "-B" types use stainless steel, and thus for the sake of simplicity are specified as "SEBS-B type")




Miniature Type

>> SEBS-B Type
- 2-row,4-point contact / retainer built-in -

This is an easy-to-install 2-row, 4-point contact structured type that keeps rails and block separate using a retainer. For moment resistant versions, wide block, long block and in addition a wide & long block version are all available. It is also possible to choose all stainless steel versions using stainless steel return caps.

Lineup

		>> SEB-A Type - 2-row,4-point contact / without retainer -



		This is an easy-to-install 2-row, 4-point contact structured type that keeps rails and block separate without a retainer. For moment resistant versions, wide block, long block and in addition a wide & long block version are all available. It is also possible to choose all stainless steel versions using stainless steel return caps.
		Lineup

		>> SER Type - crossroller -



		In addition to being extremely precise, this roller guide is minimally sized and employs a crossroller. For moment-resistant versions, in addition to the standard version, wide block is also available. By using stainless steel for "SERS type" component parts, these products can also be used in specialized environments, such as vacuums.

High-rigidty Type

>> GL Type
- 4-row,2-point contact -
Ball Cushion and NB Fiber Seat built-in

Through use of 4-row, 2-point contact design and large ball elements, and a raceway with grooves machined close to that of the ball elements making larger load capacity and longer life possible. By building-in a Ball cushion between the balls, metallic contact between individual balls is avoided, making reduced noise possible.In addition, NB's fiber sheet made from cellulose material makes lubricous management more simple.
(Low Temperature Black Chrome Treatment available as an option)

Lineup

		>> SGL Type - 4-row,2-point contact -



		Through use of 4-row, 2-point contact design and large ball elements, and a raceway with grooves machined close to that of the ball elements making larger load capacity and longer life possible. In addition, as ball elements are positioned to increase their self-aligning characteristics, the design provides absorption of dimensional error caused during installation. (Low Temperature Black Chrome Treatment available as an option)
		Lineup

		>> SGW Type - 4-row,2-point contact -



		This type is highly moment-resistant and suited to single-rail applications, due to its low height and wide profile. Similar to the "SGL type", raceway grooves are machined to a radius close to that of the ball elements, meaning that the larger contact surface provides a high load capacity and longer life. (Low Temperature Black Chrome Treatment available as an option)

SEB Type

The SEB type slide guide is a linear motion bearing in which the ball elements roll along two tracking 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.
In addition, the following specifications are available as standard options for SEB type.

standard/anticorrosion (Stainless steel is adopted in all the types -B.)
resin return cap/stainless return cap (Except for the types -WB and -A/WA)
standard block/long block	without seal/side seal	standard/light/medium pre-load
standard rail/tapped hole rail	high/precision accuracy	single/double/triple rails

SER Type

NB recieved a prize from The Japan Society for The Advancement of Inventions
for The Device Merits Prize on this product in 1993.

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.
In addition, the following specifications are available as standard options for SER type.

standard/anticorrosion	standard block/wide block	standard/tapped hole rail

without seal/side seal	high/precision accuracy	single/double/triple rails

Low Temperature Black Chrome

Low Temperature Black Chrome Treatment can be applied to our NB Slide Guides, SGL and SGW. It is a surface treatment in which electrocrystalized subatomic particles of ceramics and chrome particles are impregrated through material surface and form highly rust resisant yet thin (1 to 2 microns) and even layer of protective coating.

* Surface treatments are available for other products as Custom Option


When choosing linear system products, it is necessary to calculate elements such as load-bearing and accuracy, taking into consideration the type of machinery and environment in which the system will be used. Please refer to the Engineering Information page regarding technical calculations.
