SKF BSA CGB angular contact bearings are built for ball screw support, where rotational accuracy and the capacity to take combined axial and radial loads both matter. Machine tools, automation equipment and positioning systems rely on this series when repeatability and rigidity are part of the requirement. MR Industrial Accessories LLC supplies this line as part of its precision bearing range for customers in the United States and Latin America.
Reading the code helps narrow down the selection. BSA marks the angular contact series intended for ball screws, and the CGB suffix points to a design variant, typically tied to internal geometry, cage or preload. In examples such as BSA 204 CGB and BSA 308 CGB, the digits that follow indicate size. Before choosing a bearing, confirm the screw dimensions along with the load and speed conditions of the application.
Typical users are in metalworking, automotive and automation equipment manufacturing. You will find these bearings in machining centers, CNC lathes, milling machines and precision grinders, as well as in measuring machine screws and handling systems. Because they accept axial loads in both directions plus radial loads, they suit shafts that need high rigidity and accuracy. Printing equipment and aerospace applications also call for this type of bearing.
Selection should account for the sealing arrangement suited to the working environment, the internal clearance or preload that removes play, and whether grease or oil lubrication fits the duty. During mounting, alignment between the housings and the screw has to be precise, since even slight misalignment can shorten bearing service life. Follow the manufacturer's guidance on tightening torques and adjustment procedures.
On interchangeability, similar designations exist from other manufacturers, but dimensions and tolerances are not necessarily the same. Check the technical specifications against your equipment drawings or manuals rather than assuming a direct match. Our team can review your application and help you identify a suitable replacement.
