Deep groove ball bearings
The
most representative of rolling bearings, a wide range of uses, can
withstand radial load and double composite bearing axial load. Suitable
for high-speed rotation and low noise, low vibration occasions Sealed
bearings with steel plate dust cover or rubber seal pre-filled with the
appropriate amount of grease, the outer ring with a stop ring or flange
bearings, easy axis To the positioning, but also facilitate the installation within the shell. The maximum load bearing the same size and standard bearings, but
inside and outside the ring has a filling slot, increasing the number of
ball installed to improve the rated load.
"Self-aligning ball bearings"
Spherical
roller bearings in the two raceway inner ring and the raceway spherical
spherical surface of the outer sleeve of the car, equipped with
drum-shaped roller bearings. The
center of curvature of the outer raceway is the same as the bearing
center, so it has the same centering function as the self-aligning ball
bearings. In
the shaft, the shell appears flexing, it can automatically transfer load
and two axial direction JDB graphite copper sleeve load. Radial load capacity, suitable for heavy load, impact load situation. Inner diameter is tapered bore bearings can be installed directly. Or use the adapter sleeve, remove the cylinder mounted on the cylinder shaft. Cage using steel stamping cage, polyamide forming cage and copper alloy car cage.
"Needle roller bearings
Solid Needle Bearings
With
the inner ring bearing the same basic structure and NU cylindrical
roller bearings, but due to the use of needle roller, the volume can be
reduced, and can withstand large radial load without inner ring bearing
to the appropriate accuracy and hardness of the shaft mounting surface
as the Raceway use.
Thrust needle roller bearings
Split bearings consist of raceways and needle rollers and cage assemblies for any combination with stamped RAG or machined RAG. Non-separable
bearings by the precision stamping of the roller ring and needle roller
and cage components form a one-piece bearing. Can withstand one-way axial load of such bearings. Small footprint, is conducive to the compact design of the machine,
mostly with needle roller and cage assembly, and the shaft and housing
mounting surface as raceway surface use.
"Tapered Roller Bearings"
This type of bearing is equipped with a circular trapezoidal roller, roller guide by the inner wall. Design
so that the inner raceway surface, the outer ring raceway surface and
the roller rolling surface of the conical surface vertex intersection
point in the bearing center line. Single row bearings can withstand radial loads and unidirectional
axial load, double row bearings can withstand radial loads and two-way
axial load, suitable for heavy loads and impact loads.
"Cylindrical Roller Bearings"
Cylindrical
roller bearings can be divided into single-row, double-row and
multi-row cylindrical roller bearings according to the different number
of roller bearings installed. Which is more used is a cage with single row cylindrical roller bearings. In addition, there are other single or double row full complement roller bearings and other structures.
Single
row cylindrical roller bearings according to the ring is divided into
different N-type, NU type, NJ type, NF type and NUP type. Cylindrical
roller bearings bear the radial load capacity, according to the
structure of the ring flange can withstand a certain one-way or two-way
axial load. NN-type
and NNU-type double row cylindrical roller bearings compact structure,
strong rigidity, carrying capacity, small deformation after load, mostly
used for machine tool spindle support. FC, FCD, FCDP four-row cylindrical roller bearings can withstand large
radial loads, and more for heavy machinery such as rolling mill.
"Spherical roller bearing"
Spherical
roller bearings in the outer ring and the double raceway inner ring
with spherical roller, according to the different internal structure,
divided into R, RH, RHA and SR four types. Since
the center of the arc of the outer ring raceway is consistent with the
center of the bearing, it has self-aligning performance and therefore
can automatically adjust the axis misalignment caused by deflection or
eccentricity of the shaft or the housing. Can withstand radial load and two-way axial load. Especially radial load capacity, suitable for heavy load and impact load. Tapered bore bearings through the use of fasteners or withdrawal sleeve can be assembled on the shaft. Spherical roller bearings can withstand greater radial load, but also can withstand a certain amount of axial load. The
bearing outer ring raceway is spherical, so with self-aligning
performance, when the shaft bending or tilting the inner ring so that
the centerline and the outer ring relative tilt of not more than 1 ° ~
2.5 °, the bearing can still work .
Thrust Roller Bearing
Thrust
roller bearings include thrust spherical roller bearings, thrust
cylindrical roller bearings and thrust tapered roller bearings. Thrust
spherical roller bearings can withstand both axial and radial load, but
the radial load must not exceed 55% of the axial load. Another
important feature of this type of bearing is its self-aligning
properties, making it less sensitive to misalignment and shaft
deflection. As long as the load P and P. Not more than 0.05C, and the shaft ring rotation, the bearing allows a certain range of self-aligning angle. Small values apply to large bearings, and allowing the center of gravity to decrease as the load increases.
"Spherical Bearings"
Spherical
bearings are preferred for applications where simple equipment and
components are required, for example for agricultural machinery,
transport systems or construction machinery. Mainly
used to bear the radial load mainly radial and axial combined load, the
general should not be subjected to axial load alone, such bearings can
be installed inner ring (with the whole group of roller and cage) and
the outer ring. This
type of bearing does not allow the shaft to be tilted relative to the
housing and creates additional axial forces under radial load. The
kind of bearing axial clearance size, the bearing can work a great
relationship, when the axial clearance is too small, the higher
temperature; larger axial clearance, the bearing is easily damaged. Therefore, installation and operation should pay special attention to
adjust the axial bearing clearance, if necessary, pre-interference
installation, in order to increase the bearing rigidity.
"Joint Bearing"
Joint bearing lubrication and self-lubricating type. Joint bearing is a special structure of the sliding bearings. Its
structure than the simple rolling bearing, which is mainly composed of
an inner ring with a spherical outer ring, can withstand greater load,
according to a spherical outer ring and its different types and
structures, can withstand radial load , Axial load or radial, axial coexistence of the combined load. Generally
used for lower speed swinging movement (that is, angular transport, but
also within a certain angle for tilt (ie, aligning movement), due to
the sliding surface of the spherical dynamic), the support shaft and the
shaft housing hole concentricity Larger, still working properly
"Linear Bearings"
Linear
motion ball bearings are mainly used in mechanical equipment in a
straight line reciprocating parts, with small friction, flexible
movement and maintenance and replacement of convenience. It is widely used in textile machinery, printing machinery, medical
machinery, precision machine tools, electrical cutting machines and
automatic recorders and other fields.
"Angular contact bearings"
Angular contact ball bearings can withstand both radial and axial load, but also with the pure axial load, high speed limit. The ability of such bearings to withstand axial load determined by the
contact angle, contact angle, the ability to withstand axial load high.
Pressure Bearing
Pressure
bearing is a separate type bearings, according to its structure is
divided into one-way pressure ball and two-way pressure ball bearings. One-way
pressure bearings can withstand one direction of axial load, two-way
pressure bearings can withstand axial load in both directions. Neither of them can withstand radial loads.
