Deep groove ball bearing 6310, or single row radial, ball bearings,
It usually consist of a pair of rings, a retainer, a single row of
steel balls. Its structure is simple, easy to use, non-separable,
It is the most widely used type of bearing. This type of bearing is
mainly used to bear radial load, but it can also bear a certain
amount of axial load in either direction.
We are a manufacture specialized in producing conveyor roller
bearing. bearings also have a clearance value. This provides the
bearing room for expansion between the bearing races and will add a
small amount of play between the two rings. large clearance C3/C4
usually used in mining machine.

Professional brings quality, detail creates success
XKTE bearing's most fundamental difference is:
The other manufacturers make products considering the price cheap,
but we make products considering the service life. Each of the
idler roller bearings we produce is fully implemented in the
national standard. XKTE bearings exist for their quality and brand.
You can deny our price, but you can never find out our products'
defects in quality. XKTE conveying machinery bearing, a big brand,
is worthy of your trust.
The most important in the running of the conveyor is the idler
roller. And the most important part of the idler roller is bearing.
That is to say the selection of bearings is the top priority of the
idler roller accessories.
Let me share with you, about what the details of the processing
does a good idler roller bearing have got. How to identify idler
First, the identification of the bearing
For the low cost pursue, some small manufacturers print the black
stamps on the bearing to identify models and manufacturers, with
some very simple equipments, electro etching solutions, and very
simple templates. Because of the low cost, it is used by some
Formal manufacturers use laser engraving. The stamps are deep, have
significant dents with hand touch, good-looking, with no
breakpoints, and are never disappeared. This obviously improves the
The use of bearing retainer
Bearing retainer selection is very important. Because once too much
dust stuck into the bearing, the retainer will be first worn. If
the bearing retainer is broken, the bearing will be directly
broken. Imported bearings use big rivets to thicken retainers. XKTE
bearing is completely in accordance with the process of imported
production, so each piece of ours is made to a high quality, and
guaranteed to operate for thirty thousand hours.
Selection of nylon retainer
Nylon retainer bearing is often used in the mine. Nylon retainer
has better anti-stuck performance and wider range of temperature
than iron retainer. In the underground its anti-static performance
is also better. To get safety certificate for coal mining products
must use nylon retainer KA bearing. The selection of nylon retainer
is crucial to KA idler roller bearing, while the material of nylon
retainer must be pure and has enough toughness and strength,
because the retainer will get very soft if it is made of bad
material or mixed material, thus to make no anti-stuck performance
within the bearing.
The ring is the main part and the important part of the idler
roller bearing. Best idler roller bearing has deep groove ball, and
large clearance. But deep groove doesn't mean to dig the channel
with a simple way of enlarge the steel ball. The thickness of the
bearing is certain, so to get the ball big and the groove deep will
shorten service life. Our XKTE bearing uses way of thickening ring
to get the standard of deep groove and large clearance, improves
the anti-stuck performance, and effectively increases the service
Bearing material and hardness
Good idler roller bearing must be made of bearing steel, named
"High Carbon Chromium Bearing Steel (Fully quenched class) GCr15".
At present the standard hardness of idler roller bearing is 60-65
degree, while hardness of ring is 61-62 degree, andball is 64-65
The simple way to identify idler roller bearing is to see if its
hardness is over 60 degree, because only bearing steel can get over
Grease selection of roller bearing
Many customers ignore this most critical point. The
thirty-thousands-hours operation is a very long term. This has to
be guaranteed by enough quality and quantity grease. And this
should also be taken into account of working in different seasons.
Special note: please choose special high temperature grease if
working environment is over 120 °C for long time or low temperature
grease if it below -20 °C.
