For equipment with tight radial space and a need for rotation precision, the SKF deep groove ball bearing 619/630 N1MA is a single row, thin section design that handles moderate radial and axial loads in both directions. It is commonly found in machine tools, reducers, pumps and industrial fans. MR Industrial Accessories supplies this reference and quotes it through WhatsApp or email.
Reading the code helps when you reorder: the 619 prefix points to the thin section deep groove ball bearing series, while 630 indicates the bore diameter. The full designation 619/630 N1MA also includes the letter N and the suffix MA, which define the execution. To order a replacement, simply send the code exactly as it appears on the drawing or equipment plate.
This bearing suits applications where axial and radial space is limited but rigidity and precision are required, such as machine tool spindles, centrifugal pump shafts, induced draft fans, speed reducers and general transmission equipment. In process plants, metalworking shops and material handling operations, it is a common sight.
Selection depends on the radial and axial load the bearing will carry, the rotation speed and the environmental conditions. During mounting, use suitable tools and avoid direct blows on the rings, and verify that the shaft and housing are aligned. Lubrication and sealing should be chosen according to the application and the working environment.
If you are replacing a bearing from another brand, use the code 619/630 N1MA and its dimensional equivalents as a reference. Deep groove ball bearings of similar series are often interchangeable between manufacturers when the main dimensions and execution type match. Send us the original code and we will confirm the compatible alternative.
