Bearing with a riveted stamped steel cage
Filled up with a polyalkylene glycol/ graphite blend for lubrication
Running-in period necessary to distribute the lubricant within the bearing for applications that stand idle for a long period
Not for wet or humid environments
Single-row, pre-lubricated, typical accuracy.
Deep Groove Ball Bearings will be the most trusted rolling bearings. They are being used to accommodate radial and axial loads in both guidelines.
With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
Chromium Steel (GCr15) made out of heat treating, provides great and uniform hardness, great wear resistance, and high contact fatigue performance.
Suitable for all sorts of industrial equipment, micro motor, small rotary motor, office equipment and so on.
Cages – Selection of cage types to suit your application needs: steel, sound brass or polymer
TOP QUALITY Steel – Ultra clean metal made to extend bearing life by up to 80%

This type of ball bearing 
it often the most famous because of its versatility. They are perfect for high speeds and may handle a good radial load capability, all will very little maintenance required.
“Deep Groove” identifies the race (the groove where in fact the balls relax). There is consequently a larger space between your inner and outer rings, compared to the diameter of the ball. This leaves space for the rubber seals.
The purpose of a ball bearing is to look for the relative position of two parts (usually the shaft and the bearing housing) and also to ensure their free rotation while transmitting the load between them. At excessive rotational speeds (for example in gyro ball bearings), this application could be extended to include free rotation without practically have on in the bearings. To do this, the two elements of the bearing can be separated by a coating of adhesive liquid film named an elastic hydrodynamic lubricating film. remarked that flexibility can be maintained not only when the bearing bears the strain on the shaft, but as well when the bearing is definitely preloaded in order that the positioning reliability and steadiness of the shaft will not surpass 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly consider radial load, but can also support radial and axial load. When the just radial loads, the get in touch with angle is zero.
When the deep groove ball bearings with a larger radial clearance, with angular contact bearings can bear huge axial load, deep groove ball bearing friction coefficient is tiny, the speed limit is also high.
Single row deep groove ball bearings are manufactured as available type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings will be also stated in sealed versions with shields or get in touch with seals using one or both sides, the bearings with shields or seals in both sides are lubricated for life and are free of maintenance. A sealed bearings seals possesses speak to on the bearings interior and outer, a shielded bearings shield features contact on the outer just, and Shielded bearings happen to be primarily designed for applications where the inner ring rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at large speeds.
Double-row Deep Groove Ball Bearing possess deep uninterrupted raceways and high conformity between your balls and raceways.
They are able to carry axial loads performing in both directions furthermore to radial loads.Twice row deep groove ball bearings are
very suitable for bearing arrangements where the load carrying capacity of an individual row bearing is inadequate. For the same
external and bore diameters, twice row bearings are a bit wider than single row bearings but have considerably higher load
carrying capacity than one row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in design to standard single row deep groove ball bearings of the same size. They have no filling slots and may accommodate normal axial loads in addition to radial loads. The radial internal clearance is certainly a multiple of C5 to prevent the bearings from seizing, even though they cool swiftly. All surfaces of the bearing and shields happen to be manganese phosphated to enhance adhesion of the lubricant to the steel and provide additional protection against corrosion.
