Bearing with a riveted stamped metal cage
Filled up with a polyalkylene glycol/ graphite blend for lubrication
Running-in period required to distribute the lubricant within the bearing for applications that stand idle for a long period
Not for wet or perhaps humid environments
Single-row, pre-lubricated, ordinary accuracy.
Deep Groove Ball Bearings happen to be just about the most trusted 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 Metal (GCr15) made out of heat treating, provides large and uniform hardness, very good wear resistance, and huge contact fatigue performance.
Suitable for a myriad of industrial equipment, micro motor, tiny rotary electric motor, office equipment etc.
Cages – Variety of cage types to fit your application needs: steel, sturdy brass or polymer
High Quality Steel – Ultra clean metal designed to extend bearing life simply by up to 80%
Advanced Grease Technology – NSK lubricants designed to extend grease lifestyle and improve bearing performance
Super Finished Raceways – Specially honed to reduce noise and increase the grease distribution
Patented Seals – Give a barrier to contamination in difficult environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This type of ball bearing it often the most famous as a result of its versatility. They will be perfect for high speeds and can handle a good radial load potential, all will very little maintenance required.
“Deep Groove” refers to the race (the groove where the balls relax). There is for that reason a larger space between the 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 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 large rotational speeds (for example in gyro ball bearings), 
this application can be extended to include free rotation without practically dress in in the bearings. To achieve this, the two elements of the bearing could be separated by a level of adhesive fluid film called an elastic hydrodynamic lubricating film. pointed out that flexibility can be maintained not merely when the bearing bears the strain on the shaft, but as well when the bearing is definitely preloaded so that the positioning accuracy and stableness of the shaft does not exceed 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly consider radial load, but also can 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 speak to bearings can bear large axial load, deep groove ball bearing friction coefficient is little, the speed limit can be high.
Solo row deep groove ball bearings happen to be manufactured as start type (unsealed), sealed and shielded, the most used sizes of deep groove ball bearings happen to be also stated in sealed versions with shields or speak to seals on one or both sides, the bearings with shields or seals about both sides will be lubricated forever and are free of maintenance. A sealed bearings seals has got speak to on the bearings inner and external, a shielded bearings shield provides contact on the outer simply, and Shielded bearings happen to be primarily intended for applications where in fact the inner band rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at great speeds.
Double-row Deep Groove Ball Bearing own deep uninterrupted raceways and great conformity between the balls and raceways.
They could carry axial loads acting in both directions in addition to radial loads.Twice row deep groove ball bearings will be
very well suited for bearing arrangements where in fact the load carrying ability of a single row bearing is inadequate. For the same
outdoor and bore diameters, twice row bearings are a little 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 and style to standard one 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 internal clearance is definitely a multiple of C5 to prevent the bearings from seizing, even when they cool speedily. All floors of the bearing and shields are manganese phosphated to enhance adhesion of the lubricant to the steel and provide additional security against corrosion.
