Audited Supplier Needle Bearing
Needle bearing is a roller bearing with a cylindrical roller, which is thin and long relative to its diameter.This roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, needle bearing with fine and long roller (roller diameter D 5 mm or less, acuity 2.5 L/D, L) for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.
Type
(1) closed punching outer ring needle roller bearing(
(2) needle roller bearing with inner ring
(3) needle roller bearing without inner ring/needle bearing without inner ring without retaining frame
(4) full needle roller bearing with and without a cage
(5) They also can supply various types of needle roller bearing, 1, 2 needle cage components, no guard the needle roller bearing 3, can make 4, combined needle roller / 5, combined needle roller bearing/thrust ball bearings
(6) Combined needle/cylinder roller thrust bearing.

To properly choose a ball bearing, the important thing is to take into account several parameters:
Bearings are everywhere and therefore their applications are varied:
The application for which the bearing will be used will therefore be decisive in the choice of the part.
The ball bearing supports high speeds and reduced loads, while the tapered roller bearing supports higher loads but lower speeds.
The speed limits of a bearing are determined by the operating temperature.
The speed limit can be defined as the highest rotational speed a ride can achieve depending on use, without compromising performance and duration.
The speed limit of bearings depends on several factors, such as: bearing type, load size, tolerance class, cage configuration, work set, lubricant, lubrication and cooling conditions, etc.
2 types of loads are supported by bearings:
- Basic Dynamic Load
This is the maximum permissible load of the bearing capable of providing a nominal service life equal to 1 million revolutions.
It is necessary to calculate the service time necessary to show signs of fatigue on the materials, and on this basis to determine the theoretical duration.
- Static charge
This is the load that applies to the stationary bearing. It corresponds to a contact stress calculated between the rolling body in the most loaded contact and the raceway.
The loads are of simple type and radial, for the radial bearings, of simple type and axial, for
the abutments.
Bearing life is defined as the number of revolutions or hours of operation, which the bearing is able to withstand before signs of fatigue appear on one of the rings, on the raceway or on the rolling elements.
The rated fatigue life of an identical bearing or batch of bearings operating under the same service conditions shall be equivalent to at least a 90 degree of reliability.
The average life of a bearing lot is much greater than its nominal duration.
The nominal fatigue life is expressed as L10 (Million revolutions) or L10h (service hour).
Bearing tolerances have been standardized both nationally and internationally in accordance with ISO standards.
Bearings are generally manufactured in the P0 tolerance class.
Other parameters can be studied to choose the bearing best adapted to your needs:
The choice of bearing is therefore mainly dictated by the dimension and load characteristics to which the bearing is subjected.
In order to supply even more stable quality to our vast customers, we established a factory in Cixi city, Zhejiang province, China, near Ningbo and Shanghai port, which has recognized by special ISO. The various bearings we produce there have been inspected and confirmed by SGS to be RoHS compliant.
Besides we has a genuine concern about our customers' needs and desires, we believe that by establishing a mutually beneficial relationship with our customers we can both continue to grow and prosper, we wish and hope to always grant you satisfaction.
You have to change your ball bearing but do not know the model?
There is no written reference to it and you are lost?
You do not have a sliding foot?
The measurement of the bearing will allow you to find this bearing or an equivalent.
GNYARBearing helps you to take accurate measurement.
And do not hesitate to contact our GNYARbearings team who will be happy to inform you by phone or email.

Do you prefer that we remind you ?
Immediate and free call/email back
You now have 3 measuring elements that will allow you to identify your bearing: the inside diameter (or bore), the outside diameter, and the thickness.
You can postpone these measurements in our bearing search tool on our website

FAQ:
1. Q: If I want to mark my own brand on your bearing in small Q'ty, does it work?
A: Yes, we can engrave your own brand on the rings of bearing in small Q'ty.
If the future, when you have larger Q'ty, we can open the cover mold of your own brand name.
2. Q2. Does your company accept the small quantity of orders?
A: Once your bearing is standard size bearing, we accept the small Q'ty even in 1pc.
3. Q: will you send me free sample?
A: Yes, sample is free, but the freight cost has to be paid by you.
4. Q :If I don't see the type of bearing I need, what should I do?
A: we have too many bearing series number. Sometimes, we are unable to put them all on the Alibaba. Just send the inquiry to us, and we'll send you the detail of your bearing.
5. Q: Why is your bearing price higher than others?
A: our bearing value is most cost-effective for you to use,the most suitable bearings is the best bearing for our every customer.
