NB Corporation

NB is recognised as an international leader in the world of linear motion technology. Since its founding in 1939, NB has emerged as the leading manufacturer of high quality linear motion products in Japan, setting new international standards for performance and quality control industry wide. Their growth and high degree of product acceptance can be attributed to unique product designs, attention to detail and fresh approaches to meeting the linear motion needs of customers.

The NB linear system is a linear motion mechanism which utilizes the recirculating movement of ball or roller elements to provide smooth and accurate linear travel. NB offers a wide range of linear motion products that may contribute to the size and weight reduction of machinery and other equipment, while providing dependable performance in high-precision equipment.

Advantages:
Low friction and excellent responce:
The dynamic friction of rolling ball or roller elementsis substantially lower than that of full-face surfacesliding friction. Since the difference between rolling dynamic and static friction is small, motion responce is excellent and results in superior dependable movement. This also allows for easy fabrication of mechanisms requiring precise positioning or high-speed acceeration.

High precision and smooth movement:
The NB linear system is designed for smooth rolling movements. The rolling element's raceway contact surface is finished through high precision grinding. The recirculating movement of the rolling elements allow for continual high-precision linear movement without clearence.

High Load Capacity and long Travel Life:
Although the NB linear system is designed to be compact, the use of large rolling elements and machined raceway surface results in high load capacity and long travel life.

Ease of Instalation:
The NB linear system shortens machining and assembly time when compared with that of a full face surface sliding bearing system.

Variety of models:
A wide varielty of models and types of NB systems are available for just about any shape or material option. This permits the selection of the best appropriate linear component for any application.

SKF Linear Motion

SKF's wide range of linear products allows you to choose the ideal product for your application. The champions for shock resistance are precision rail guides, planetary roller screws and the specialist product, shock absorbers. Their robust design and construction have already proved their capabilities in the automotive, machine tool, defense and steel industries.

Whether the load is static or dynamic, whether applied occasionally or continuously in 24-hour 7-day duty cycles, needle roller precision rail guides, heavy-duty linear ball bearings and roller screws have proved themselves in the automotive, electronic, steel and plastics industries where productivity and non-stop production are vital. SKF's wide range of linear products also offer high levels of precision. Precision rail guides permit guiding accuracy to 1 µm and preloaded recirculating roller screws achieve 1 µm positioning accuracy. Examples include optimizing the shape of telescope mirrors, dressing grinding wheels and checking electronic components.
