How to identity the quality of conveyor
idler roller bearing? A hammer will make you an expert!
As a conveyor idler manufacturer, do you
worry about the bearing quality while do not have precision testing equipment?
Now XKTE will tell us how to identify
quality of conveyor idler roller bearing with a hammer:
Find a hammer, set ball bearing upright. Then
crack the bearing open.
* Good Material bearing—Outer ring break,
will not be deformed
* Poor material bearing--- poor hardness,
easy to deform, easy to leave marks
Thin Retainer
The thin retainer has been deformed badly
after the bearing has been smashed, small rivet can not play the role of stability.
Once conveyor roller seals fail, dust enters into race, it will Increase running
resistance, it is likely to be jammed, serious heating, lubrication failure,
retainer cracked and ball scattered, finally cause damage to the conveyor idler
roller.
Thick Retainer
While the thick retainer and rivets are
still in good condition
Inner & Outer
Ring
*after smashing the bearing, clean the oil of rings with cotton and watch the groove carefully, we can identify the processing technology by the depth of groove.
Same models usually use same size of steel balls.
*Digging groove bearing usually use thin rings, so the groove is very shallow.
*Grinding groove bearing use thicker rings
*Grinding groove bearing: The rings adopt
super finished surface technology, polished surface and
on the edge of groove, there are chamfers that
can avoid bumping and noise.
*Digging groove bearing: rough surface without
chamfer.

If you do not have caliper, the thickness
of the material can be judged by the chamfer.
To save the cost, digging groove bearing
usually uses thin inner ring, and use small chamfer to make the inner ring appear
thicker.
The most important in the running of the conveyor is the idler roller. And the most important part of the idler roller is bearing.
XKTE’s suggestion:
Do not reduce service life in order to save
the cost
It’s not only the cost of few cents, but
the quality of product.
