 What is spherical roller bearing?

Self-aligning roller bearing is between in a two roll way inner ring and outer raceway for spherical , assembly with drum roller bearing.

Spherical roller bearing profile:

It's have two columns roller,main bear radial load, at the same time also can bear any direction axial load.Have high radial load capacity. Especially suitable for heavy duty or vibration work under load,but can't bear pure axial load. This kind of bearing's outer ring raceway is spherical shape, so its self-aligning performance is good, can compensate for the coaxiality error.

USA car bearing spherical roller bearings 22217 distributor Designs and Structures

CTN1: Nylon retainer.
C: Stamped steel retainer and strengthened symmetric rollers; offers considerably higher load ratings than conventional designs for a broad range of applications and long service life.
CA: Alternative design of C design; Precision-machined one-piece brass retainer and strengthened symmetric rollers; used to exchange with C design, especially for large size.
MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers; equivalent to C design in load capacity.
CC: steel cage, replace traditionalbrass cage.
E: Third generation design.
The bearing contact is completely optimized and has improved stress distribution; offer much longer service life than normal designs.

Post code

1) The internal structure of the code is that the same type of bearings of different internal structures, the basic code followed by the letter said. Such as: contact angle of 15 °, 25 ° and 40 ° of angular contact ball bearings were used to C, AC and B that the different internal structure.

2) bearing the tolerance level is divided into two, 4, 5, 6, 6X-and 0, and a total of 6 levels, followed by senior to junior, the code was / PZ, / P4 '/ PS, / P6, / P6X and / PO. Level of tolerance, 6X-level only applies to tapered roller bearings; 0 for the general level, the code does not mark the wheel bearing. .

3) commonly used in the radial bearing clearance series is divided into group 1, group 2, 0, group 3, 4 and 5 groups of 6 groups, followed by small to large radial clearance. o Group clearance clearance is commonly used groups are not marked in the bearing code, the rest of the code in the bearing clearance in the group respectively / CI, / CZ, / C3, / C4, / CS said.
