Bearing with a riveted stamped metal cage
Filled up with a polyalkylene glycol/ graphite mix for lubrication
Running-in period necessary to distribute the lubricant within the bearing for applications that stand idle for an extended period
Not for wet or humid environments
Single-row, pre-lubricated, usual accuracy.
Deep Groove Ball Bearings happen to be probably the most trusted Deep Groove Ball Bearing china rolling bearings. They are being used to support radial and axial loads in both guidelines.
With small friction and high-limit speed, Ball Bearings are cost-effective and need little maintenance.
Chromium Metal (GCr15) made with heat treating, provides excessive and uniform hardness, great wear resistance, and high contact fatigue performance.
Suitable for all types of professional equipment, micro motor, small rotary electric motor, office equipment etc.
Cages – Variety of cage types to suit your application needs: steel, stable 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
Very Finished Raceways – Specially honed to minimize noise and increase the grease distribution
Patented Seals – Provide a barrier to contamination in rough environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This type of ball bearing it often the most used as a result of its versatility. They happen to be ideal for high speeds and will handle a good radial load capacity, all will very little 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 rings, than the diameter of the ball. This leaves space for the rubber seals.
The objective 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 high rotational speeds (for instance in gyro ball bearings), this application could be extended to include free rotation without almost dress in in the bearings. To achieve this, the two elements of the bearing can be separated by a level of adhesive liquid film called an elastic hydrodynamic lubricating film. pointed out that flexibility could be maintained not merely when the bearing bears the load on the shaft, but as well when the bearing is preloaded in order that the positioning precision and steadiness of the shaft will not surpass 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 only 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 huge axial load, deep groove ball bearing friction coefficient is small, the speed limit is also high.
Single row deep groove ball bearings are manufactured as open up type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings happen to be also stated 
in sealed versions with shields or speak to seals using one or both sides, the bearings with shields or seals on both sides will be lubricated forever and are free of maintenance. A sealed bearings seals offers get in touch with on the bearings internal and external, a shielded bearings shield has got speak to on the outer simply, and Shielded bearings are primarily meant for applications where the inner ring rotates. If the external ring rotates, you will find a risk that the grease will leak from the bearing at large speeds.
Double-row Deep Groove Ball Bearing currently have deep uninterrupted raceways and huge conformity between the balls and raceways.
They are able to carry axial loads performing in both directions in addition to radial loads.Dual row deep groove ball bearings will be
very suitable for bearing arrangements where the load carrying capability of an individual row bearing is inadequate. For the same
exterior and bore diameters, twice row bearings are a bit wider than sole row bearings but have considerably higher load
carrying capacity than sole row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in design and style to standard solo row deep groove ball bearings of the same size. They have no filling slots and will accommodate regular axial loads in addition to radial loads. The radial internal clearance is definitely a multiple of C5 to prevent the bearings from seizing, even when they cool speedily. All surfaces of the bearing and shields are manganese phosphated to enhance adhesion of the lubricant to the metallic and provide additional proper protection against corrosion.
