Our all cylindrical roller bearingproducts are strictly follow ISO9001 standard for production. Each bearing will be 100% quality-tested, such as hardness, roughness, flaw detection, elemental analysis, metallographic analysis, and size requirements, to ensure that 100% qualified products are provided.

It is suggested to select appropriate lubrication based on the evaluation of working temperature of the system design engineer. It includes: rotation speed,load and its type and environmental temperature.

Introduction to Thin-section Bearings Thin-section bearings are also known as slim bearings. The cross-section dimension is independent of bore diameter; therefore, thin-section bearings are also called uniform-section thin bearings.

CHG high precision thin section bearing mainly include thin section angular contact ball bearings, thin section radial contact ball bearings, thin section four pointcontact ball bearings, precision ball bearings and crossed cylindrical rollerbearings, crossed tapered roller bearings. Products are widely used inindustrial robots, aerospace, precision medical equipment, radar antennas andoptical equipment etc.

we have developed bearings 61868, 61880, 61892, 61896, 618/530, 618/630, 618/750, 618/850, 618/980, which have gained high recognition and good reputation among our customers. At present, the strander bearing in our company has formed our own features: high speed, high precision, long service life, low vibration and low noise.

The various types of vibration and sound in rolling bearings can be grouped in four main categories: structural, manufacturing, handling and other. The structural vibration consists mostly of race, click, squeal and cage noise: it can be continuous or intermittent depending on specific cases
