NTN has developed a resource-saving lightweight wheel bearing. The weight of the entire wheel bearing is reduced by about 10% compared to the original product. The burr and chip are reduced. The data yield after progressive processing; The amount of data used in the outer wheel has been reduced by 20%. The policy is to achieve annual sales of 10 billion yen in 2010.
The chamfered portion and the depressed portion of the original cutting treatment are attached with a metal oxide film such as a cast outer surface. Others; the original rounded flange is extended outward from the stud bolt; Different shapes. There is no one-week connection in the section of the Wheel Pilot; it is divided into 5 fixing bolts.

Fused Silica Ball Lens

Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.Half ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
