Product Introduction of Self-aligning Roller Bearings

In the core rotating components of mechanical equipment, self-aligning roller bearings, with their outstanding performance and reliable quality, have become the key support in numerous industrial fields. Our self-aligning roller bearings, through exquisite craftsmanship and innovative design, provide ideal solutions for various demanding working conditions.
I. Structural Design: Ingenious Design, Unparalleled Quality
Our self-aligning roller bearings feature a meticulously crafted structure. The inner ring is equipped with two precisely inclined raceways, like a dedicated track for the rollers, guiding the rollers to run smoothly; the outer ring adopts a unique shared spherical raceway, this ingenious design is the core for achieving automatic alignment function. Two rows of drum-shaped rollers are evenly distributed between the inner and outer rings, they are the main force for transmitting loads, closely cooperating to ensure the stable operation of the bearing. Combined with a high-strength cage, it effectively separates the rollers and prevents them from colliding and interfering with each other, while precisely guiding the rollers to roll orderly along the raceways, significantly improving the operating efficiency and stability of the bearing.
II. Performance Characteristics: Multiple Advantages, Standing Out
(1) Strong Radial Load Capacity
The double-row design of our self-aligning roller bearings grants them an extremely strong radial load capacity. In heavy-duty working conditions, such as heavy material transportation in large mining machinery or huge rolling forces in metallurgical equipment, the two rows of rollers within the bearing can evenly distribute the radial load and efficiently transfer it to the inner and outer ring raceways. Compared to single-row bearings, it can easily withstand several times or even dozens of times the radial force, providing a solid guarantee for the stable operation of the equipment under heavy-load conditions.
(2) Excellent Self-aligning Performance
Self-aligning is the unique charm of self-aligning roller bearings. During actual operation, due to shaft deflection deformation, installation errors, or equipment vibration, the shaft and bearing housing often have misalignment. However, our self-aligning roller bearings, with the spherical raceway of the outer ring and the inclined design of the inner ring raceway, can automatically adjust the position of the rollers, making the rotational center of the bearing quickly align with the actual center line of the shaft. This outstanding self-aligning performance effectively avoids local overload, increased wear, and abnormal vibration caused by misalignment, significantly extending the equipment's service life and improving operational stability and accuracy.
(3) Good Impact Resistance
Considering the frequent challenges of impact loads in industrial environments, our self-aligning roller bearings pay special attention to impact resistance in design and material selection. The sturdy structure combined with high-quality materials, like wearing a layer of strong armor for the bearing, can efficiently absorb and disperse impact energy. Whether it is the intense impact of a crusher or the huge impact force of a crane lifting heavy objects, the bearing can quickly adapt and maintain normal operation, ensuring the reliable operation of the equipment in harsh conditions.
III. Types Abundant: Multiple Choices, Wide Adaptability
(1) By Inner Hole Form Classification
Cylindrical Inner Hole Self-aligning Roller Bearings: Suitable for conventional installation scenarios where the shaft neck is cylindrical. Installation is convenient, and they can be closely connected with the shaft through interference or clearance fit. Widely used in equipment with high installation precision requirements, such as motors and reducers, ensuring precise connection between the shaft and the bearing to achieve efficient and stable operation of the equipment.
Conical Inner Hole Self-aligning Roller Bearings: The inner hole is conical, with common cone ratios of 1:12 and 1:30. When combined with conical shaft necks, the inner ring can move axially flexibly, precisely adjusting the radial clearance of the bearing, meeting the special requirements of different working conditions for clearance. Combined with locking sleeves or disassembly sleeves, they can also be easily installed on smooth shafts or stepped shafts, performing well in equipment such as mining machinery and paper machinery that require frequent disassembly and installation of bearings.
(2) By Cage Type Classification
Steel Plate Pressed Cage Self-aligning Roller Bearings: Using high-strength steel plate pressing to form, it is cost-effective and has high production efficiency. Compact structure, lightweight, it can stably guide the rollers and ensure their smooth and stable movement in the raceways during high-speed operation of the bearing. This product is suitable for mechanical equipment in general working conditions such as ventilation equipment and small transmission devices. While ensuring performance, it effectively controls costs.
Solid retaining ring self-aligning roller bearing: Made of high-quality materials such as copper alloy, aluminum alloy or high-strength engineering plastics, it has high strength and excellent wear resistance. Compared to steel stamping retaining rings, the solid retaining ring structure is more sturdy and can withstand greater loads and higher rotational speeds. During operation, it can better fit the movement trajectory of the rollers, reducing friction and wear between them, significantly improving the service life and reliability of the bearing. It is commonly used in heavy-load, high-speed equipment with strict bearing performance requirements such as steel rolling machines, large crushers, wind turbines, etc.
