Deep Groove Ball Bearings are the most widely used rolling bearings. They are being 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 Metal (GCr15) made with heat treating, provides large and uniform hardness, great wear resistance, and great contact fatigue performance.
Suitable for all sorts of commercial equipment, micro motor, small rotary electric motor, office equipment and so forth.
Cages – Selection of cage types to suit your application needs: steel, sturdy brass or polymer
High Quality Steel – Ultra clean steel made to extend bearing life by up to 80%
Advanced Grease Technology – NSK lubricants designed to extend grease existence and improve bearing performance
Extremely Finished Raceways – Specially honed to minimize noise and enhance the grease distribution
Patented Seals – Give a barrier to contamination in troublesome environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This kind of ball bearing it often the most used because of its versatility. They happen to be ideal for high speeds and can handle a good radial load potential, all will hardly any maintenance required.
“Deep Groove” refers to the race (the groove where the balls relax). There is therefore a larger space between the 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 look for the relative position of two parts (usually the shaft and the bearing housing) also to ensure their free rotation while transmitting the strain between them. At excessive rotational speeds (for instance in gyro ball bearings), this application can be extended to include free rotation without nearly wear in the bearings. To achieve this, the two parts of the bearing could be separated by a coating of adhesive liquid film named an elastic hydrodynamic lubricating film. pointed out that flexibility can be maintained not only when the bearing bears the strain on the shaft, but likewise when the bearing can be preloaded in order that the positioning precision and stableness of the shaft will not exceed 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 contact angle is zero.
When the deep groove ball bearings with a more substantial radial clearance, with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is tiny, the speed limit is also high.
Solitary row deep groove ball bearings will be manufactured as open type (unsealed), sealed and shielded, the most used sizes of deep groove ball bearings are also stated in sealed versions with shields or contact seals using one or both sides, the bearings with shields or seals upon both sides will be lubricated for life and are maintenance free. A sealed bearings seals possesses contact on the bearings interior and external, a shielded bearings shield provides contact on the outer just, and Shielded bearings will be primarily 
intended for applications where in fact the inner band rotates. If the outer ring rotates, there exists a risk that the grease will leak from the bearing at high speeds.
Double-row Deep Groove Ball Bearing own deep uninterrupted raceways and substantial conformity between your balls and raceways.
They are able to carry axial loads acting in both Deep Groove Ball Bearing china directions in addition to radial loads.Dual row deep groove ball bearings are
very suitable for bearing arrangements where in fact the load carrying capability of a single row bearing is inadequate. For the same
outdoors and bore diameters, dual row bearings are a bit wider than solo row bearings but have considerably higher load
carrying capacity than solo row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in design to standard solo row deep groove ball bearings of the same size. They have no filling slots and can accommodate typical axial loads furthermore to radial loads. The radial interior clearance is a multiple of C5 to prevent the bearings from seizing, even when they cool speedily. All surfaces of the bearing and shields will be manganese phosphated to improve adhesion of the lubricant to the metal and provide additional protection against corrosion.
