Load Rating & Life:

Lubrications:

Before SGC miniature bearings leave factory,the open bearing is filled with meter anti-rust oil only;while the shielded bearing has been filled with general bearing grease,which makes it suitable for light and medium load as well as low and medium speed applications, with a working temperature ranging from -30℃~100℃.If the bearings are applied beyond the above conditions, other special grease or lubricating methods shall be employed.
