A ball bearing is a type of rolling-element bearing that uses balls
to maintain the separation between the bearing races.
The purpose of a ball bearing is to reduce rotational friction and
support radial and axial loads. It achieves this by using at least
two races to contain the balls and transmit the loads through the
balls. In most applications, one race is stationary and the other
is attached to the rotating assembly (e.g., a hub or shaft). As one
of the bearing races rotates it causes the balls to rotate as well.
Because the balls are rolling they have a much lower coefficient of
friction than if two flat surfaces were sliding against each other.
Ball bearings tend to have lower load capacity for their size than
other kinds of rolling-element bearings due to the smaller contact
area between the balls and races. However, they can tolerate some
misalignment of the inner and outer races.
Basic type; With snap ring groove on the outer ring (-N); With one
shield (-Z) on one side or two shields (-2Z) on both sides; With
one seal (-RS) on one side or two seals (-2RS) on both sides.

Catalog of Deep groove ball bearing
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.
First, the identification of the bearing
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.
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 life.
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

Started 2006, We are a manufacture of industrial Bearing in
Liaocheng Shandong, concentrates on manufacturing industrial
bearing, mainly used in conveying equipment, machinery, textile,
chemical, auto motor and so on. Especially bearing for conveyor,
which make us become one of well-known enterprise in China. We have
26 production lines, mainly produce deep groove ball bearing,
spherical roller bearing, TN Nylon cage bearing and sealed bearing.
All of Our products are made of Chrome Steel GCr15, with grinding
groove and superfinishing technology. Supply ability is about 20000
Pieces / per Day. We have our own brand XKTE, and we can also
provide OEM service.
I couldn't find a design to fit my application in your catalog. Can
you help me design a bearing?
Yes, technical expertise is available to assist you with
engineering design for custom products. Available options include,
but are not limited to, custom rings, retainers, balls, shields,
lubricants, and packaging. We look forward to working with you to
satisfy your rotary motion requirements.
What causes bearing noise?
Bearing noise is a function of both the bearing and the way it is
used. Some external factors that affect bearing noise include
lubricant type, excessive bearing load, and improper installation.
Once the abnormal noise occurred, you can contact our engineers, we
will help you find the reasons and provide the appropriate
What is the difference between using a shield or a seal as a ball
Shields or seals are often installed to retain lubricant and to
prevent contamination from entering the bearing. While a shield
contacts the outer ring and does not come in contact with the inner
ring, the seal generally comes in contact with both the inner and
outer rings. Torque or drag is lower with a shield than with a
seal. Alternately, the seal provides a higher degree of protection
from contamination. Shields and seals are available in a variety of
materials and configurations.
XKTE developed a serious of sealing methods for different
applications. Please contact a XKTE engineer for technical
assistance with any special requirements.
