Linear ball bushings have a high load capacity and are self-aligning. They provide 3 times the load capacity and up to 27 times the normal travel life of conventional slide bushings and are completely interchangeable with traditional linear systems. They are extremely smooth running and cost-effective because their higher load capacity and longer travel life reduces material and maintenance cost. For these reasons they are designed to suit many different applications such as factory automated equipment, machine tools, industrial machines, electrical equipment, optical and measuring instruments.

NB produces a wide range of slide units. Their high-quality and high precision blocks increase the accuracy of machinery and other equipment.
The blocks can be constructed of resin to reduce cost and weight. The use of standard shaft end supports and shaft support rails simplifies mounting. Two different types of linear units are available, each made of different materials (cast-iron, aluminum alloy, ABS resin).


The slide bush is a high performance bushing with 3 times the load capacity and the capability to provide 27 times the normal travel life of a conventional bushing. The TOPBALL is available in a variety of configurations to fit different applications.

NB’s self aligning can be designed into many different applications such as factory-automation equipment, machine tools, industrial machinery, optical and measurement instruments and electrical equipment.
