Bearing with a riveted stamped steel cage
Filled up with a polyalkylene glycol/ graphite mix for lubrication
Running-in period required to distribute the lubricant within the bearing for applications that stand idle for an extended period
Not for wet or perhaps humid environments
Single-row, pre-lubricated, normal accuracy.
Deep Groove Ball Bearings will be the most widely used rolling bearings. They are used to support radial and axial loads in both directions.
With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
Chromium Steel (GCr15) made with heat treating, provides huge and uniform hardness, great wear resistance, and huge contact fatigue performance.
Suitable for all kinds of professional equipment, micro motor, small rotary electric motor, office equipment and so forth.
Cages – Variety of cage types to suit your application needs: steel, sturdy brass or polymer
High Quality Steel – Ultra clean metal designed to extend bearing life by up to 80%
Advanced Grease Technology – NSK lubricants made to extend grease existence and improve bearing performance
Extremely Finished Raceways – Specially honed to reduce noise and increase the grease distribution
Patented Seals – Provide a barrier to contamination in hard environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This type of ball bearing it often the most popular due to its versatility. They happen to be well suited for high speeds and can handle a good radial load capacity, all will very little maintenance required.
“Deep Groove” refers to the competition (the groove where in fact the balls rest). There is as a result a larger space between your inner and outer bands, than the diameter of the ball. This leaves space for the rubber seals.
The purpose of a ball bearing is to determine the relative position of two parts (usually the shaft and the bearing casing) and also to ensure their free rotation while transmitting the load between them. At excessive rotational speeds (for instance in gyro ball bearings), this application can be extended to add free rotation without nearly put on in the bearings. To achieve this, the two parts of the bearing can be separated by a layer of adhesive fluid film named an elastic hydrodynamic lubricating film. remarked that flexibility can be maintained not merely when the bearing bears the strain on the shaft, but likewise when the bearing is certainly preloaded to ensure that the positioning reliability and stability of the shaft does not exceed 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly take radial load, but can also support radial and axial load. When the just radial loads, the contact angle is zero.
When the deep groove ball bearings with a more substantial radial clearance, with angular get in touch with bearings can bear huge axial load, deep groove ball bearing friction coefficient is tiny, the speed limit can be high.
One row deep groove ball bearings are manufactured as start type (unsealed), sealed and shielded, the most used sizes of deep groove ball bearings are also stated in sealed versions with shields or speak to seals on one or both sides, the bearings 
with shields or seals on both sides happen to be lubricated for life and are free of maintenance. A sealed bearings seals features contact on the bearings inner and external, a shielded bearings shield has get in touch with on the outer only, and Shielded bearings will be primarily designed for applications where the inner band rotates. If the outer ring rotates, you will find a risk that the grease will leak from the bearing at large speeds.
Double-row Deep Groove Ball Bearing own deep uninterrupted raceways and substantial conformity between the balls and raceways.
They are able to carry axial loads acting in both directions in addition to radial loads.Dual row deep groove ball bearings happen to be
very suitable for bearing arrangements where the load carrying capability of an individual row bearing is inadequate. For the same
external and bore diameters, twice row bearings are a bit wider than one row bearings but have considerably higher load
carrying capacity than solitary row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in style to standard sole row deep groove ball bearings of the same size. They haven’t any filling slots and can accommodate normal axial loads in addition to radial loads. The radial internal clearance is a multiple of C5 to avoid the bearings from seizing, even though they cool rapidly. All areas of the bearing and shields happen to be manganese phosphated to improve adhesion of the lubricant to the metal and provide additional protection against corrosion.
