CF12-1UU-AB skf roller bearing
Needle roller bearing features:
Needle roller bearing with pressed outer ring is made of high-quality thin sheet by fine stamping process. It has such characteristics as small structure space and large load capacity, and is suitably used for the place where the installing space is limited and case hole cannot be used as the rolling race. Further axial orientation is not necessary after pressing into the bearing seat hole. B series are inch-size drawn cup full complement needle roller bearings with open end.
Widely used in automobiles, motorcycles, power tools, textile machines, farm machines, printers, etc.
Needle roller bearing model series: NK, NKS, RNA49, RNA69, RNA49-RS, RNA49-2RS
Our company are specialized in manufacturing various types of bearings and we also accept OEM service with SKF NSK KOYO NTN etc brand.
We can produce the bearings accordingly to the customers' samples or drawings.
Our products are in good quality and reasonable prices
