A: What does bearing CA/CC/W33 mean？
CA means copper retainer
CC means steel retainer
W33 means that the outer ring has oil grooves and three oil holes
These are the codes of spherical roller bearings
B: Spherical roller bearing clearance standard?
The internal clearance of standard spherical roller bearings is C2, Standard (CN), C3, C4 and C5, all complying with GB4604
C:Spherical roller bearings can be divided into:
(1) Miniature bearings - bearings with a nominal outer diameter of 26mm or less;
(2) Small bearings, the nominal outer diameter is 28-55mm;
(3) Small and medium-sized bearings - bearings with a nominal outer diameter range of 60-115mm;
(4) Medium and large bearings - bearings with a nominal outer diameter range of 120-190mm
(5) Large bearings, the nominal outer diameter range is 200-430mm;
(6) Extra-large bearings - bearings with a nominal outer diameter of 440mm or greater.
