Spherical roller bearings with two rows of rollers, the main path of a load, but also can withstand axial load in either direction. A high radial load capacity, especially suitable for heavy work loads or vibration, but can not bear pure axial load. This kind of bearing outer ring raceway is spherical shape, so its good aligning performance, can compensate concentricity error.
Spherical roller bearings cylindrical bore and tapered bore tapered conical bore two were 1: post code 12 is K Spherical roller bearings (153 000 113 000 type or type) and 1: 30, post code for the K30-aligning roller bearings. This type of bearing and shaft with a conical, axial movement of the inner ring of the bearing can be adjusted radial clearance.
The post code is K, K30 conical bore spherical roller bearings, mounted on an adapter sleeve to match, became the post code for the K + H type and K30 + H bearings. Such bearings can be installed in no on the optical axis of the shaft shoulder for installation and removal of bearings require frequent occasions.
In order to improve the lubrication performance of the bearing in the bearing outer ring tank car and the three drill hole uniformly distributed, then set code is W33.
Spherical roller bearings have two raceways between the inner and outer ring raceway is spherical, the assembly of a drum-shaped roller bearing outer ring raceway curvature center bearing center line, so has with self-aligning ball bearing with the same self-aligning feature in the shaft. deflection occurs when the shell can be automatically adjusted without increasing the burden bearing.
Cage with steel stamping cage. Forming polyamide cage and copper alloy cutting cage.
Self-aligning roller bearings have two inner raceway, outer ring of spherical roller, a drum-shaped rolling element bearings, the outer ring raceway center and bearing center line. Consequent, with self-aligning properties, even if between the shaft and the bearing housing there are errors or shaft flexing so inclined inner and outer rings of the occasion can also be used normally.
Such bearings can withstand radial load, axial load and synthetic load capacity is large, suitable to withstand vibration, shock load applications.
In addition to the inner diameter of the cylindrical bore bearings also produce tapered bore diameter bearings tapered bore bearings in the basic model with sign 'K', ordinary taper of 1/12, but the 240 and 241 series bearings taper 1/30, basic No later signed 'K30'. tapered bore bearings almost entirely using adapter or withdrawal sleeves are fixed to the shaft.
Specific classification and model control:
1, spherical roller bearings (20000 CC type)
2, tapered bore spherical roller bearings (20000 CCK type)
3, self-aligning roller bearings (20000 CC / W33 type)

5, mounted on an adapter sleeve bore spherical roller bearings (20000 CCK + H0000 type)
6, mounted on an adapter sleeve bore spherical roller bearings (20000 CCK / W33 + H0000 type)
