SKF single row deep groove ball bearings

Single row deep groove ball bearings are with particularly wide application. This type of bearing is designed to be simple, suitable for high speed, even for very high speed and very durable in operation, almost no maintenance. Deep groove of Bearing Raceway and the high tie between raceways and balls,make deep groove ball bearings can bear radial loads and axial loads in both directions, even at high speeds as well.

SKF single row deep groove ball design

Basic design of SKF single row deep groove ball bearings are open (non-sealed). Because of manufacturing concerns, non-sealed bearings the same size as sealed bearings or dust-proof bearings, might have the seal groove in the outer ring.

SKF single row deep groove ball bearings with normal radial internal clearance as standard. Most bearings with C3 radial internal clearance. Some bearings even with smaller C2 or larger radial internal clearance C4 or C5. In addition, you can provide internal clearance of deep groove ball bearing of the range reduces or offsets. These special clearance can be used to narrow the standard clearance range or adjacent clearance Division, please see the “supplementary designations” designation suffix CN in the next section. On request, can also supply non standard internal clearance of bearings.
Radial internal clearance values are provided in table 3. These values are consistent with ISO 5,753 standards in 1991, apply to bearings before mounting the clearance value when there is no load.
Generally matched bearings
60, 62, and 63 series bearings with axial internal clearance and preload values are shown in table 4.
SKF single row deep groove ball bearings misalignment
Single row deep groove ball bearings withstand the misalignment capacity is limited. The permissible angular displacement between the inner and outer rings (that is not produced in the bearing can ill afford the extra high pressure angular displacement) is given. Depends on:
Due to the complexity of the relationship between these factors, so cannot provide general numerical values. Based on the differential impact of these factors to allow angular displacement of between 2 and 10 arc min. Any misalignment will cause increased bearing noise and reduced life expectancy.
SKF single row deep groove ball bearing cage
Depending on the bearing series and size, SKF single row deep groove ball bearings are fitted with one of the following cages:

Standard design bearings with a pressed steel cage, also equipped with machined brass injection moulded cage of polyamide 6,6. Work at higher temperatures, polyamide 4,6 or PEEK cage may be a significant advantage.
SKF single row deep groove ball bearings with supplementary designations
Used to represent certain features of SKF deep groove ball bearing designation suffix as described in below.
CN General radial clearance; only with the following combination of narrow clearance or transfer letter
These letters are combined with clearance of the following constituencies: C2, C3, C4 and C5, for example C2H.
C2 is smaller than normal clearance of radial internal clearance
C3 is greater than the normal radial internal clearance clearance
C4 is greater than C3 radial internal clearance
C5 is larger than C4 radial internal clearance
