Is This The Linear Motion Component You’re

Using For Wafer Manufacturing?

We're not referring to linear bearings that incorporate ball bearings - meaning friction is reduced between moving parts by recirculating (usually metal) balls. We're referring to the bearing most in demand for movement that requires the highest degree of precision - such as microprocessor manufacturing, diagnostic equipment and automation.

It is Crossed-Roller bearing guides/slideways that are proven to excel. Read on for the 5 design characteristics that facilitate their precision:

Travel Limits – Because there is little or no difference between static and dynamic frictional resistances – even under low-load conditions – crossed roller bearings are well suited for minute motion. 

Wear – For motion control applications with extremely fast acceleration and deceleration (at dimensions ranging from 30-600mm lengths, 2-12 mm rollers) endurance can be 150 million cycles.

Smoothness – A benefit of not recirculating is less frictional resistance fluctuation making them extremely quiet and smooth.

Accuracy and Deflection – Crossed rollers provide a larger contact area than ball bearings. That reduces elastic deformation. Because of this greater stiffness, crossed rollers provide consistently precise movement. Often the bearings can be specified with mounting tables hone to exacting standards. Since for ultra precision, 2 microns is the maximum allowable deflection from the mounting surface. 

Anti-Cage Creep Mechanism – NB has developed the anti-creep device that eliminates ‘creeping’ of the retainer, so the slideway can be used in any mounting direction and with lower momentum motors such as linear motors.

When Accuracy Is Paramount

NB stroke bush is ideal for applications that require precise linear motion, such as CNC machines, robotic arms, and automation equipment. They are also used in medical devices and lab equipment where accuracy is paramount. 

Stroke bushings are all about precision because they maintain excellent exact linear positioning, making them indispensable in automation systems and precision machinery.

The NB stroke bush is a linear and rotational motion mechanism using the rotational motion of ball elements between an outer cylinder and a shaft. It is compact and withstands high loading. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved in high-speed and high-acceleration conditions. Although the linear motion is limited to a specific stroke length, the combined rotation and stroke motion is executed with very little frictional resistance.
