☆ product features
Spherical Roller Bearing with 2 spherical roller, a common outer ring of concave spherical roller, and there are two inner bearing axis tilt angle of a concave raceway, the outer ring raceway curvature of the center and center bearing the same . Spherical Roller Bearing is a self-aligning, and the shaft bearings from the wrong box or shaft deflection deformation of the impact of compensation can be caused by concentricity error. In addition to the type of bearing radial load to bear, the bear can also be a two-way axial load and load the joint, large carrying capacity, at the same time has good anti-vibration, anti-shock ability. Self-aligning roller bearings are mainly used in steel, mining, paper, shipping, textile machinery, coal, electric power industry in a variety of mechanical equipment, machine-building industry is the most widely used in a class of bearings.
★ product categories
ZWZ production of Spherical Roller Bearing can be divided into the following types:

Cylindrical hole-aligning roller bearings
Cone hole-aligning roller bearings
Shaker with Spherical Roller Bearing
Split-aligning roller bearings
Cylindrical hole-aligning roller bearings
According to the inner wall and the use of any of the cage, CA and can be divided into two C-. CA-aligning roller bearings at both ends of two small inner wall, no wall in the middle, Cage Shuangzhua for one entity structure of the cage, materials for the general carbon steel or copper, the large-scale structure of the bearings, bearing large With a more; C-aligning roller bearing inner ring without large and small wall, roller "guide" for activities in the middle Dang Quan, Cage for stamping steel cage, the structure of the roller bearings Sub-length, rated load to increase, but also has higher speed and lower limit friction wear and tear.

Cone hole-aligning roller bearings
With a cylindrical hole-aligning roller bearings characteristics, but inside the cone hole to hole, for the conventional taper 1:12, the model for basic bearings model after K; but the 240 and 241 series bearings to taper 1:30, and its model Bearing for the basic model after K30. Cone hole bearing nut can be directly mounted on a cone on the journal can also be used through the tight set, or sets of shift in the fixed set of cylindrical shaft.

Shaker with Spherical Roller Bearing
New anti-vibration-aligning roller bearings, machine vibration is ZWZ to host special category of research and development of a new structure of the bearing, but also to the general mechanical devices. Performance: the carrying capacity of high impact resistance, anti-vibration, the friction of small, low temperature rise, long service life.
The use of the basic size, with fixed in the inner wall, can withstand axial force; special cage structure, with diameter two-way guidance, control and guide the gap with the cage, the outer ring of the volume of a rocky ledge , To vibration and vibration.
Shaker with self-aligning roller bearings with post signs VB code.

Split-aligning roller bearings
The main types of bearings used in hard-to-reach location of the bearing, or non-use of split bearings, as well as the need for a lot of time and manpower to carry out maintenance or replacement of expensive and result in downtime costs of the application. For example, or the long axis of the crankshaft.
ZWZ according to user needs to provide different design Split-aligning roller bearings. To meet the requirements of the installation, the bearing kinds of commonly used Split, the outer ring, inner ring wide with two tight circle card can be set to play better and better cope with the role.

Split-aligning roller bearings with post-D code symbol
Mid-size range
ZWZ-aligning roller bearings of the basic dimensions are listed in size datasheets bearings,
Diameter size range: 30mm ~ 1800mm
Outside diameter size range: 68mm ~ 2180mm
Size range width: 20mm ~ 530 mm
 
● Tolerance
ZWZ-aligning roller bearings with precision products P0 and P6 level, for users with special requirements also Machinable P5-class products, with tolerance and GB307.1.
 
◇ radial clearance
ZWZ-aligning roller bearings with C2, the standard (CN), C3, C4 and C5-level internal space, and all with GB4604. Cone hole-aligning roller bearings are C3 space as a standard clearance. Its &#118alue is not applicable to the installation and non-load bearing.
For greater than or less than the &#118alue of the standard clearance bearings can be manufactured in accordance with user requirements. Shaker with self-aligning roller bearings for the C4 group clearance.
◆ Cage
The CA-aligning roller bearings, Cage generally brass, bronze or steel cage, and other entities, the C-aligning roller bearings, steel cage generally punching Cage.

For non-standard cage bearing structure, prior contact with the ZWZ.
□ equivalent dynamic load
When Fa / Fr ≤ e,
P = Fr + Y1 Fa
When Fa / Fr> e,
Pr = 0.67Fr + Y2 Fa
