Bearing with a riveted stamped steel cage
Filled up with a polyalkylene glycol/ graphite mixture 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, regular accuracy.
Deep Groove Ball Bearings happen to be just about the most widely used 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 need little maintenance.
Chromium Steel (GCr15) made with heat treating, provides large and uniform hardness, good wear resistance, and substantial contact fatigue performance.
Suitable for all types of professional equipment, micro motor, small rotary electric motor, office equipment etc.
Cages – Selection of cage types to fit your application needs: steel, solid brass or polymer
High Quality Steel – Ultra clean metal designed to extend bearing life simply by up to 80%
Advanced Grease Technology – NSK lubricants made to extend grease life and improve bearing performance
Extremely Finished Raceways – Specially honed to reduce noise and improve the grease distribution
Patented Seals – Give a barrier to contamination in tough environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This sort of ball bearing it often the most used because of its versatility. They will be well suited for high speeds and may handle an excellent radial load capability, all will very little maintenance required.
“Deep Groove” refers to the competition (the groove where the balls rest). There is as a result a larger space between the inner and outer bands, than the diameter of the ball. This leaves space for the rubber seals.
The objective of a ball bearing is to determine the relative position of two parts (usually the shaft and the bearing housing) also to ensure their free rotation while transmitting the load between them. At substantial rotational speeds (for instance 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 can be separated by a layer of adhesive liquid film called an elastic hydrodynamic lubricating film. remarked that flexibility could be maintained not only when the bearing bears the load on the shaft, but also when the bearing is usually preloaded in order that the positioning accuracy and stableness of the shaft does not go beyond 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly have radial load, but also can 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 speak to bearings can bear large axial load, deep groove ball bearing friction coefficient is little, the speed limit can be high.
Single row deep groove ball bearings will be manufactured as open up type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings will be also stated in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals in both sides happen to be lubricated for life and are free of maintenance. A sealed bearings seals has got contact on the bearings interior and outer, a shielded bearings shield has got speak to on the outer just, and Shielded bearings are primarily intended for applications where the inner ring rotates. If the outer 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 great conformity between your balls and raceways.
They could carry axial loads acting in both directions in addition to radial loads.Twice row deep groove ball bearings happen to be
very well suited for bearing arrangements where the load carrying capacity of an individual row bearing is inadequate. For the same
external and bore diameters, double row bearings are a little bit wider than single row bearings but possess 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 to standard one row deep groove ball bearings of the same size. They haven’t any filling slots and may accommodate usual axial loads in addition to radial loads. The radial internal clearance is usually a multiple of C5 to avoid the bearings from seizing, even when they cool rapidly. All areas of the bearing and shields will be manganese phosphated to improve adhesion of the lubricant to the metallic and provide additional proper protection against corrosion.
