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 a long period
Not for wet or perhaps humid environments
Single-row, pre-lubricated, normal accuracy.
Deep Groove Ball Bearings happen to 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 Metal (GCr15) made with heat treating, provides excessive and uniform hardness, good wear resistance, and substantial contact fatigue performance.
Suitable for all varieties of professional equipment, micro motor, little rotary engine, office equipment etc.
Cages – Selection of cage types to suit your application needs: steel, sound brass or polymer
High Quality Steel – Ultra clean steel made to extend bearing life by up to 80%
Advanced Grease Technology – NSK lubricants made to extend grease lifestyle and improve bearing performance
Super Finished Raceways – Specially honed to minimize noise and enhance the grease distribution
Patented Seals – Give 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 as a result of its versatility. They are perfect for high speeds and may handle a good radial load ability, all will hardly any maintenance required.
“Deep Groove” identifies the competition (the groove where in fact the balls relax). There is as a result a larger space between your inner and outer rings, compared to 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 casing) and ensure their free rotation while transmitting the strain between them. At large rotational speeds (for instance in gyro ball bearings), this application can be extended to include free rotation without practically don in the bearings. To achieve this, the two elements of the bearing could be separated by a layer of adhesive fluid film named an elastic hydrodynamic lubricating film. remarked that flexibility could be maintained not only when the bearing bears the strain on the shaft, but likewise when the bearing is definitely preloaded in order that the positioning precision and steadiness of the shaft will not go beyond 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 simply radial loads, the speak to 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.
Solo row deep groove ball bearings will be manufactured as open 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 using one or both sides, the bearings with shields or seals about both sides happen to be lubricated for life and are free of maintenance. A sealed bearings seals features get in touch with on the bearings inner and external, a shielded bearings shield has get in touch with on the outer just, 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 excessive speeds.
Double-row Deep Groove Ball Bearing include deep uninterrupted raceways and huge conformity between your balls and raceways.
They are able to carry axial loads performing in both directions in addition to radial loads.Double row deep groove ball bearings are
very ideal for bearing arrangements where the load carrying ability of a single row bearing is inadequate. For the same
outdoors and bore diameters, dual 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 design and style to standard single row deep groove ball bearings of the same size. They have no filling slots and may accommodate normal axial loads furthermore to radial loads. The radial interior clearance is normally a multiple of C5 to avoid the bearings from seizing, even though they cool swiftly. All areas of the bearing and shields happen to be manganese phosphated to enhance adhesion of the lubricant to the metallic and provide additional safeguard against corrosion.
