Can SKF bearings BECBM and BECBP be used interchangeably?
Thread Content
Can bearings with different cage materials be used interchangeably? Which specification is higher?
The dimensions are the same; M refers to a brass retainer that is machined, while P refers to a nylon retainer. Do not use nylon retainers in high-temperature conditions. Of course, the price of BECBM is higher; the difference in price is quite significant
The cage material is different. B: 40° contact angle E: internally optimized design CB: bearings mounted in any configuration (general-purpose bearings) ； Before installation, when paired back-to-back or face-to-face, the axial internal clearance is equal to that of the standard series P: injection-molded glass fiber-reinforced nylon 6,6 cage, with rolling elements for guidance. M: Brass solid cage.
