Welcome Vikash Trading Company and Shri Kataria Electriclas come visit our factory in Liaocheng, Shandong. These two customers from India came to find deep groove ball bearings.
In our company, we share the knowlegde about what is a good bearing. How to identify deep groove ball bearings?
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 inferior
products.
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 bearing
grade.
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 a deep groove ball bearing. Deep groove ball 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.
Good deep groove ball bearing must be made
of bearing steel, named "High Carbon Chromium Bearing Steel (Fully
quenched class) GCr15" At present the standard hardness of deep groove ball bearing is 60-65 degree, while hardness of ring is 61-62 degree, and ball is
64-65 degree.
The simple way to identify deep groove ball bearing is to see if its hardness is over 60 degree, because only bearing steel
can get over this degree.
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.
