Refinement method of radial rolling bearing

Rolling bearing guide rails have the advantages of flexible motion, low friction torque and large bearing capacity compared with ball guides. They are widely used in vertical and side guiding systems for ultra-precision machining machines and precision test instruments (such as coordinate measuring machines). The linearity of the rolling bearing guide rail is related not only to the straightness of the guide rail itself, but also to the rotational accuracy of the radial rolling bearing. A commercially available standard radial roller bearing for high speed

Cryo Tube

Yongyue cryo vials are made of medical grade polypropylene (PP) and have no endotoxin. They are disposable laboratory consumables specially used for storing biological samples.
The anti-slip texture of the cap and body is easy to screw cap.
The tube cap has an O-ring built-in gasket to prevent liquid leakage.
The cryo tube is suitable for ultra-low temperature refrigerators, and the tolerance temperature is -86~121 °C, and it can be repeatedly frozen and thawed.
In the gaseous state of liquid nitrogen, it can withstand low temperature to -167 ℃.
According to different requirements, there are ordinary grade and PCR grade. PCR grade products are free of DNase, RNase, endotoxin and foreign DNA. Sterilized by gamma irradiation, sterile.
