About Self-Aligning Ball Bearing (Spherical Roller Bearings) :
Spherical roller bearings with two rollers, the main path a load to bear, but also can withstand axial load in either direction. High radial load capacity, especially for heavy loads or vibration, but can not afford a pure axial load. This kind of bearing outer ring raceway is spherical shape, so the aligning good performance, to compensate concentricity error.
Spherical roller bearings have two symmetric spherical roller, spherical outer ring raceway of a shared, there are two inner bearing axis tilted at an angle with the roller, aligning with a good performance, when the axial force When installed in a different mind bending or normal use of still bearing, concentric with the bearing size series of transfer varies, generally allow aligning angle is 1 to 2.5 degrees, the load bearing capacity of the larger type, in addition to radial loads outer bearings can withstand axial load in both directions, with good impact resistance, in general, self-aligning roller bearings to allow the work speed is low.
Spherical Roller Bearings by roller-shaped cross-section shape is divided into symmetrical and asymmetrical spherical roller spherical roller-shaped structure of two different, non-symmetrical spherical roller bearings are early products, the key for the host service, a new design host are very rarely used symmetrical spherical roller bearings, the internal structure of fully improved design and parameter optimization, and early production of spherical roller bearings, can withstand greater axial load, the operation of these bearings lower temperature, it can be adapted to the requirements of high speed, according to whether the inner wall and the use of cage can be divided into two kinds of C-type and CA, C-type bearing is characterized by inner wall and the use of pressed steel cage, CA-type characteristics, compared with the inner sides of the bearing wall and the use of cars are solid cage in order to improve the bearing lubrication, provides the user with an outer ring of the tank and three hole Spherical roller bearings to the bearing post code / W33 said that according to the requirements of users can also supply with inner hole of the spherical roller bearings, in order to facilitate customer handling and replacement of bearings, but also provide the hole with a taper The self-aligning roller bearings, tapered bore, taper 1:12 after the set, code-named K said, in order to meet special user requirements are also available for the 1:30 taper bore bearings, then set the hole with a code-named K30 taper bearing lock nut can be directly mounted on the tapered journal bearings, but also can make use of an adapter sleeve or withdrawal sleeves will be installed in the cylindrical journal bearings on. In order to ensure that the bearings at high speeds to prevent the centrifugal effect in the raceway and roller slip between the harmful, the bearings should be the minimum radial load to bear a certain size can be estimated following formula:
Fr = 0.02C
Where
Fr - minimum radial load N
C-bearing basic dynamic load rating N
Equivalent dynamic load
P = Fr + Y1Fa when Fa / Fr e when
P = 0.67Fr + Y2Fa when Fa / Fr e when
Where
P-equivalent dynamic load N
Y1 Y2-axial dynamic load factor
Equivalent static load
P0 = Fr + Y0Fa
Where
P0-equivalent static load N
Y0-axial static load factor
Spherical Roller Bearing Type:
Spherical Roller Bearings
Spherical roller bearings are divided into: a cylindrical bore, tapered bore.

Tapered bore taper 1:12, respectively, the post code for the K,-aligning roller bearings (153 000 type or 113 000-type) and 1:30 of the post code for the K30 self-aligning roller bearings. This type of bearing shaft with a conical distribution, the inner ring can be adjusted along the axial movement of the bearing radial clearance.
Spherical Roller Bearings Rear Code:
The post code-named K, K30 conical bore spherical roller bearings, mounted on an adapter sleeve to match, then a post-code for the K + H-and K30 + H-type bearings. In the absence of such a bearing can be mounted 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 outer ring tank car and a uniform distribution of the three drill hole, then set code-named W33.
Different types of spherical roller bearings:
Example: NTN LH series of self-aligning roller bearings
The application of self-aligning bearing gradually increased, especially in high temperature environment, long-life bearings. For different application environments, NTN engineers developed STJ2 type of steel, in a wide temperature range from room temperature to 250 ºC temperature range to extend the service life. This is the LH series of steel self-aligning roller bearings standard materials. The bearing characteristics are as follows (with SUJ2 contrast) a large temperature range of long-life bearings, at room temperature is 3.5 times the life of ordinary materials in high temperature (250 ºC) is under 30 times the life of ordinary materials to prevent surface damage, 7times the capacity of anti-flaking, anti-abrasion ability 1.4 times, 2.5 times the anti-wear ability, dimensional stability under high temperature conditions, at 250 ºC when almost no change in size, to enhance fatigue rupture strength at high temperatures and tight fit cases, increased by 2 times the anti-fracture fatigue life. 2-fold increase in anti-fatigue rupture strength, simplify storage management program components, from room temperature to 250 ºC can use a single standard bearing types, self-aligning roller bearings will gradually turn into "LH series."
Spherical roller bearing cage and their uses
Mainly used to maintain frame: sheet steel cage (suffix E), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined solid brass cage (suffix M), where the vibration sheet steel cage (suffix JPA)
Main use: paper machinery, deceleration devices, railway vehicles axles, rolling mill gear box seat, sub-roller rolling mill, crusher, vibrating screen, printing machinery, woodworking machinery, various types of industrial gear, vertical seat adjustment with the heart bearings.
Spherical roller bearings installed
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical, the assembly of a drum-shaped roller bearings. Outer ring raceway curvature center and bearing center line, so has the same self-aligning ball bearing self-aligning feature. In the shaft, deflection occurs when the shell, you can automatically adjust the direction of axial load and two loads. Radial load capacity, suitable for heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or use the sleeve, remove tube installed in the cylinder axis.Pressed steel cage with cage, polyamide forming cage and copper alloy machined cage. For the self-aligning bearings, the bearings in the shaft into the box with the shaft hole, use the middle ring to prevent installation of tilt and rotate the outer ring. It should be remembered that some dimensions of self-aligning ball bearing ball bearing protruding from the side, so the middle ring should be installed recessed to prevent damage to the ball. A large number of bearings are generally mechanical or hydraulic pressure into the method for installation.
For the separable type bearings, inner and outer rings can be installed separately, thus simplifying the installation process, especially when the rings are required, especially when the interference fit. Already in place in the inner shaft into the outer ring of the bearing box included, must pay attention to see whether the right of the inside and outside the ring, to avoid scratching the bearing raceways and rolling elements. If the cylindrical and needle roller bearings without flanges or side of the inner wall of the inner flange, the recommended installation sleeve. Sleeve diameter inner ring raceway diameter should be equal to F, machining tolerances to be d10. Needle roller bearings is best installed using the mandrel.

Production process :

1. Abrasive machining of steel pipe;

2. The inner & outer ring grinding;

3. The precision work of inner ring & outer ring;

4. Bearing cleaning;

5. The Assembly of inner ring , outer ring , bearing balls & cage, etc;

6. Bearing inspection( precison, noise & vibration levels);

7. Packing: in plastic tube, then in carton & pallet or in color single box, then in carton & pallet, or as the customers' request...
