Spherical roller bearings with two rows of rollers, the main radial load, but also can withstand any direction of the axial load. Has a high radial load capacity, especially for heavy duty or vibration load, but can not afford pure axial load. This type of bearing outer ring raceway is spherical, so the aligning performance is good, to compensate for coaxial error.
Longma spherical roller bearings have two symmetrical spherical roller, the outer ring has a common spherical roller, the inner ring with two inclined axis of the bearing axis of the raceway, has a good self-aligning performance, when the shaft by the Force bending or installation of different heart can still be used when the bearing, aligning with the bearing size series vary, generally allow the adjustment angle of 1 to 2.5 degrees, the type of bearing load capacity, in addition to bear radial Load external bearings can also bear the role of axial load in both directions, with good impact resistance, in general, spherical roller bearings allow the work of low speed.
Longma-aligning roller bearing according to the roller cross-sectional shape is divided into symmetrical spherical roller and asymmetric spherical roller two different structures, asymmetric spherical roller bearing is an early product, mainly for the mainframe maintenance services, the new The design of the host is rarely used symmetric spherical roller bearings, the internal structure of a comprehensive improvement in design and parameter optimization, and early production of spherical roller bearings compared to bear greater axial load, the bearing of the Low operating temperature, it can adapt to the requirements of higher speed. According to whether the inner ring and the cage with the cage can be divided into two different types of C and CA, C-type bearing is characterized by no inner wall and the use of steel stamping cage, CA-type Terrain bearings The inner ring on both sides of both sides of the car and the use of physical cages in order to improve the bearing lubrication can be provided to the user with the outer ring ring groove and three oil holes of the spherical roller bearings to bearing rear Code / W3, according to the users requirements can also be supplied with the inner ring of the oil hole of the self-aligning roller bearings, in order to facilitate customer handling and replacement of bearings, but also provide taper with the taper roller bearings, tapered hole Taper 1:12 after the code-named K said that in order to meet the requirements of special users can also provide the bore taper 1:30 of the bearings, and its post code-named K30 bore with taper bearings can be directly with the lock nut bearing Mounted on the taper journal, the bearing can also be mounted on a cylindrical journal with the aid of an adapter or withdrawal sleeve.
