In mining equipment, metallurgical machinery, conveyor systems and heavy-duty industrial applications, bearings are often required to operate stably for long periods of time under high loads, axial misalignment and harsh environments. 12, 13, 22 series self-aligning roller bearings are designed for such conditions, and have become the core transmission components in many industrial equipment due to their excellent self-aligning and load-carrying capabilities. With excellent self-aligning capability and load bearing performance, they have become the core transmission components in many industrial equipments.
Self-aligning roller bearings adopt a double-row roller structure with a spherical raceway, which enables the bearings to automatically compensate for slight misalignments between the shaft and housing during operation. This structural advantage allows them to maintain smooth operation even under conditions of equipment mounting errors, shaft deflection or thermal deformation, significantly reducing abnormal wear and the risk of failure.

● Spherical roller bearings of series 12
Series 12 bearings have a compact structure and relatively lightweight external dimensions, and are suitable for medium loads and high speed requirements.
They are commonly used in machinery and equipment where space is limited but operational stability is required.
Overview of features:
Small size, flexible installation
Good centering performance
Suitable for continuous operation
● 13 Series Spherical Roller Bearings
While maintaining a compact design, the 13 series has further enhanced load carrying capacity, making it suitable for applications with frequent load changes or shock loads.
Features Overview:
Higher radial load carrying capacity
High tolerance for mounting errors
Suitable for medium to heavy duty industrial equipment
● 22 Series Spherical Roller Bearings
The 22 series is one of the most widely used series of spherical roller bearings, combining high load carrying capacity with stable running performance to cope with heavy loads, low speeds and severe operating conditions.
Extremely strong radial and certain axial load carrying capacity
Adapt to high shock, strong vibration environment
Long service life and low maintenance frequency
1. Automatic self-aligning, reduce equipment failure rate
Even if there is deviation in the axis, the bearing can automatically adjust the running angle, effectively reducing the edge stress concentration and prolonging the life of the bearing and the whole machine.
2. High bearing capacity, suitable for heavy-duty working conditions
Double-row roller structure enables the bearings to withstand a large radial load, and at the same time can withstand a certain direction of the axial force, suitable for long-term operation of heavy equipment.
3. Stable operation, reduce maintenance costs
Reasonable internal structure and roller distribution, so that the bearings in the high load still maintain stable operation, help to reduce downtime and maintenance expenses.
4. Wide adaptation to complex environments
Whether it is dust, high humidity, shock and vibration, or high load continuous operation, 12 / 13 / 22 series can maintain reliable performance.
Mining crushing and screening plants
Metallurgical and continuous casting equipment
Cement lines and rotary machines
Conveyor systems, gearboxes
Fans, paper and heavy machinery
When selecting a model, it is recommended to take the following factors into consideration:
Equipment load size (medium / heavy duty)
Installation space constraints
Existence of axial misalignment
Operating speed and operating conditions
For heavy loads and high impact conditions, the 22 series is usually a safer choice; for higher requirements on compactness and speed, the 12 or 13 series is more advantageous.
Series 12, 13 and 22 spherical roller bearings are widely used in various industrial equipment due to their mature structural design and reliable performance. This series of bearings is undoubtedly a trustworthy choice for users who pursue long-term stable operation, reduce maintenance costs and improve the reliability of the whole machine.
