I need to purchase 2 ball bearings for a cement mixer. The number on the original bearings is “6007 2RSR C3”. I understand that the first number (or any number in first position) indicates that it is a metric bearing (the 6).
I understand that the second number, the zero, indicates “extra light”. Does this mean it is lightweight, as in not heavy duty with a short lifespan?
I have had this cement mixer for upwards of 20 years and I have replaced these bearings twice before. I was wondering if I could buy bearings of the same exact size but heavier duty that would last longer.
the chart I looked at on the internet gave the following ratings.
0 Extra light
1 Extra light thrust
So would a bearing of number 6307 2RSR C3 be the same exact bearing but longer-lasting? I need a crash course here from someone who knows.
