23228 Self-Aligning Double Row Roller Bearings: Excellent
Guarantees For Industrial Operation
In the complex operation system of industrial equipment, bearings,
as key components, directly affect the stability and service life
of the equipment. The 23228 self-aligning double row roller bearing
has become an ideal choice for many industries due to its unique
design and excellent performance.
I. Highlights of Structural Design
The structural design of the 23228 self-aligning double row roller
bearing is ingenious. Its double row roller layout significantly
enhances the radial load-carrying capacity, enabling it to easily
cope with the strong radial forces generated during the operation
of large-scale equipment. At the same time, the bearing has a
self-aligning function. The raceways of the inner and outer rings
are spherical, allowing the shaft to deflect or misalign within a
certain angle range. This effectively avoids abnormal wear caused
by installation errors or vibrations during equipment operation,
ensuring the stable operation of the equipment.
II. Accurate Dimensional Parameters
- Inner diameter: 140mm, which precisely fits many industrial shaft diameter
specifications, ensuring a tight fit with the shafts of various
equipment and realizing efficient power transmission.
- Outer diameter: 250mm, the outer diameter size is carefully calculated and
optimally designed to provide sufficient structural strength for
the bearing while ensuring good compatibility with external
equipment components.
- Width: 88mm, the reasonable width design ensures the load-carrying
capacity of the bearing while taking into account the compactness
of the entire equipment, meeting the installation requirements
under different space constraints.
III. Excellent Performance Parameters
- Rated dynamic load: The rated dynamic load of 23228 self-aligning double row roller
bearings from different brands varies slightly. For example, the
rated dynamic load of NSK's 23228CE4 bearing can reach 835,000N,
while some high-quality bearings can exceed 1,000,000N, such as
some products reaching 1,040,000N. This means they can stably
maintain normal working conditions under the working conditions of
high-speed operation of equipment and frequent impact and
vibration.
- Rated static load: It is usually at a high level of around 1,300,000N, enabling the
bearing to effectively support the static weight of the equipment
during the static or start-up phase of the equipment, preventing
permanent deformation caused by overload, and prolonging the
overall service life of the bearing and the equipment.
- Limiting speed: The limiting speed varies under different lubrication conditions.
When lubricated with grease, it can generally reach 1100rpm,
meeting the equipment operation requirements under most
conventional working conditions; when lubricated with oil, the
limiting speed can be increased to 1500rpm or even higher. For
example, when using oil bath lubrication, in accordance with the
ISO 15312 standard, the thermal speed rating can reach 1800min⁻¹.
Under a well-designed and strictly controlled forced circulation
oil lubrication system, the speed can soar to 2600min⁻¹, adapting
to the harsh requirements of high-speed operation equipment.
IV. High-Quality Manufacturing Materials
- Bearing rings: High-quality bearing steel such as 52100 chromium steel is mostly
used. It has high strength and hardness, can effectively resist
various stresses borne by the bearing during operation, and has
good wear resistance, which greatly prolongs the service life of
the bearing rings and ensures the long-term stability of the
overall performance of the bearing.
- Rollers: High-performance materials such as 52100 chromium steel are also
used, which are matched with the bearing ring materials to ensure
excellent contact and rolling performance between the rollers and
the bearing rings, reduce friction and wear during operation, and
improve the operating efficiency and reliability of the bearing.
- Cages: Common materials include steel and brass. The cage plays an
important role in the bearing by evenly separating the rollers,
guiding the movement of the rollers, and maintaining the stability
of the rollers. Cages of different materials are suitable for
different working environments and load conditions. For example,
under high-speed and light-load working conditions, brass cages are
more suitable due to their good wear resistance and
self-lubricating performance; while in working scenarios with heavy
loads and strong impact, steel cages have more advantages due to
their higher strength and rigidity.
V. Diverse Application Fields
- Metallurgical industry: In the process of steel production, many key equipment such as
large rolling mills and continuous casting equipment generate huge
vibration and impact during operation and are often in
high-temperature environments. The high load-carrying capacity and
self-aligning characteristics of the 23228 self-aligning double row
roller bearing enable it to operate stably under these harsh
working conditions, ensuring the continuity and efficiency of the
production process and providing a solid guarantee for the stable
production of the metallurgical industry.
- Mining machinery: Mining equipment such as crushers, ball mills, and belt conveyors
face complex working conditions such as heavy loads and severe dust
pollution for a long time. The 23228 bearing, with its excellent
load-carrying performance, can bear the huge weight and impact
force of ores. At the same time, its self-aligning function can
effectively deal with the shaft misalignment problem caused by the
equipment operating in complex terrain, significantly reducing
equipment failure rates and improving mining efficiency.
- Power industry: Whether it is large steam turbines and generators in thermal
power generation or fan main shafts in wind power generation, they
have extremely high requirements for the reliability and stability
of bearings. The 23228 self-aligning double row roller bearing can
provide stable support for power equipment under high-speed and
high-load conditions, ensuring the accurate operation of the
equipment and guaranteeing the continuous and stable power supply.
- Engineering machinery: Engineering machinery such as excavators, loaders, and cranes
frequently experience drastic changes in load and direction
conversion during operation. The 23228 bearing, with its strong
load-carrying capacity and good adaptability, can maintain
excellent performance under complex and changing working
conditions, providing reliable guarantees for the efficient
operation of engineering machinery and helping various engineering
construction projects proceed smoothly.
