Bearings
WHY 440C STAINLESS steel?
Good corrosion resistance to water and many weak chemicals
Corrosion resistance can be improved by passivation
Good for temperatures up to 300°C
Slightly softer than chrome steel so lower load ratings
Will corrode in salt water or salt spray and poor resistance to acids/alkalis
More expensive than chrome steel

F A Q
1. Why do the bearings I received have shaking?
The clearance of the bearing is related to the play.
The default is the standard C0 clearance, which is usually 3-18um.
The corresponding principle is shown in the figure below.
If you dont need to shake, please choose C2 small clearance bearing.
If you have any questions, please contact us before purchasing.
2. What is the accuracy of ABEC-7?
ABEC is the American ANSI standard.
The corresponding German DIN standard and international ISO standard are as follows:
