In the spherical roller bearing,

the retainers are made of copper and iron Gang, three, these three kinds of material holder and the respective advantages and disadvantages is what?

Now the spherical roller bearing stamping steel C, copper CA, improved steel cage EA, they first have: good abrasion resistance, good dimensional stability, good mechanical strength.

EA type bearing with high load capacity, low torque; copper CA temperature can not exceed 300 DEG C.

Stamping steel C has much higher than the rated load of traditional products, a wide range of applications, the advantages of long service life;
