There is a high radial load capacity, especially suitable for heavy load or vibration load, but can not bear pure axial load. The outer race of the bearing ring is spherical, so its aligning performance is good, can compensate the coaxial error.
Two rows of symmetrical spherical roller, the outer ring has a common spherical raceway and the inner ring two and a bearing axis inclined at an angle to the raceway, with good aligning performance, when the axial force bending or installed in a coaxial bearing can still be used normally, adjustable mind varies with the size of bearing series, generally allowed by aligning angle is 1-2.5 degrees, this type of bearing load capacity is larger, not only can bear radial load bearing can bear bidirectional axial load, with good impact resistance, generally spherical roller bearings allow the working speed is low.
Spherical roller bearing is divided into symmetrical and non symmetrical spherical roller spherical roller two different structure according to roller shape, non symmetrical spherical roller bearing is the early products, mainly for the host service, the new design is rarely used host symmetrical spherical roller bearing, through the comprehensive improvement of internal structure design and parameter optimization, compared with the spherical roller bearing early production, able to withstand greater axial load, the bearing operating temperature is low, so it can adapt to high speed requirements, according to the inner ring without flange and the holder is not the same can be divided into C type and CA type two, C type bearings without inner ring ribs and is the stamping steel cage, the characteristics of CA type bearing inner ring for Trent on both sides of the wall and the used car business entity retainer. In order to improve bearing lubrication, to the user to provide outer ring spherical roller bearing with annular groove and three oil hole, expressed as a bearing post code /W33. According to the requirements of the user can also supply with spherical roller bearing inner ring oil hole, in order to facilitate customer handling and replacement of bearings, with taper roller bearings with inner hole, taper taper 1:12, after placing code is k said, in order to adapt to the user's special requirements can also provide taper 1:30 of the bearing and the rear code for the K30. The bearing with the taper of the inner hole can be directly mounted on the conical shaft neck by the locking nut, and the bearing can be installed on the cylindrical shaft neck by means of a tight set or a withdrawal sleeve.
Spherical roller bearings are divided into: cylindrical hole, tapered bore. Tapered bore taper 1:12 rear code for K spherical roller bearing type 153000 or 113000 (type) and 1:30 post code for K30 of spherical roller bearing, respectively. This kind of bearing shaft with a conical distribution, inner ring along the axial movement of the bearing can adjust radial clearance.
Post code: the rear code for K, K30 taper hole self-aligning roller bearings installed in the tight match sets on, become rear code for K and K30 + H type bearings. This kind of bearing can be installed on the axis of the shaft shoulder, which is suitable for the occasion of the need to install and remove the bearing frequently. In order to improve the lubrication performance of the bearing, the ring oil groove is drilled in the outer ring of the bearing and the three oil holes are drilled with uniform distribution. The rear code is W33.
The main application of the holder: stamping steel plate reinforced type holder (suffix E, domestic rarely). Stamping steel plate type holder (suffix CC), glass fiber reinforced polyamide 66 holder (suffix TVPB), machined brass two piece holder (suffix MB). Machine processing Brass integral type holder (suffix CA), vibration stamping steel plate holder (suffix JPA). Vibration occasion brass cage (suffix EMA). The same structure, the code on the bearing or different.
Main uses: papermaking machinery, speed reducer, railway vehicle axle, rolling mill gear box bearing seat, roll of a rolling mill, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical adjustable pillow block bearing in mind.
