NTN/NSK single row angular contact bearing
Core Tip: NTN/NSK single row angular contact bearing suffix means: B40 contact angle; A25 contact angle; C15 contact angle; J pressure steel cage; LI machined copper alloy cage; DB back to back configuration
The suffix of NTN/NSK single row angular contact bearing means: B——40° contact angle; A——25° contact angle; C——15° contact angle; J——compressed steel cage; LI——machined copper Alloy cage; DB - back-to-back configuration; DF - face-to-face configuration; CS - radial clearance greater than standard clearance (SKF uses axial clearance). A typical NTN bearing model is exemplified by the 7310BDB. In many users' bearing warehouses, it has been found that most of these bearing cages are crushed steel cages rather than brass cages. The standard accuracy of NTN/NSK single row angular contact bearings is normal, and the pairing is done in the bearing manufacturer. SKF bearing accuracy is P6 grade, and the bearing is “arbitrarily assembled”, which greatly facilitates the user's use and optimal management of inventory. In contrast, NTN and NSK bearings have a common level of accuracy, and the pairing is done in the manufacturing plant, so they are not interchangeable, and the user has to strictly follow the bearing specified model.
