Tapered Roller Bearing

The Tapered Roller Bearing is a type of separate-type bearing. Its core structure consists of tapered raceways and tapered rollers. The extension lines of the roller axes converge at the axis center, achieving pure rolling transmission. It is designed to handle heavy combined loads, offering strong load-bearing capacity and excellent positioning rigidity.

Structure and Features:

Separate-type Design:The inner ring assembly (including inner ring, rollers, and cage) is detachable from the outer ring. This allows for easy installation and disassembly; the inner and outer rings can be assembled independently, making it suitable for various shaft seat structures.
Pure Rolling Transmission: The rollers are in line contact with the raceways, and their extension lines converge at the axis center. This results in low friction loss, high transmission efficiency, and smoother operation.
Heavy Load-bearing:The contact angle (typically ranging from 10° to 30°, with a maximum of 29° for large cone angles) determines the axial load-bearing capacity. A larger contact angle signifies greater axial load capacity, enabling it to withstand heavy radial loads and unidirectional axial loads simultaneously.
Flexible Configuration: It supports single-row, double-row, four-row, and paired installations. The internal clearance and preload can be adjusted to meet diverse load and precision requirements. It is compatible with both metric and inch systems, making it suitable for the international market.

Main application scenarios:

Widely adapted for automotive hubs, differentials, and transmissions, as well as construction machinery such as excavators and cranes. It is also used in heavy-duty and high-impact conditions like mine crushers, metallurgical rolling mills, industrial reducers, and oil drilling rigs. It serves as a core bearing component in the transmission systems of heavy equipment.

Angular contact ball bearing

Angular contact ball bearings are a type of precision bearings that can simultaneously bear radial loads and unidirectional axial loads. Their key feature lies in the existence of a nominal contact angle. The larger the contact angle, the stronger the ability to bear axial loads.

Structure and Features:

Contact angle design: There is a fixed contact angle between the bearing raceway and the balls, which determines the distribution ratio of radial and axial loads. The 15° series is suitable for high-speed and light-load applications; the 25° or 40° series can withstand greater axial heavy loads.
High precision grade: Widely adopts P4, P5 and above precision grades, with high dimensional accuracy and small rotational error, capable of achieving stable operation under high-speed rotating conditions.
Contact stress optimization: The balls and raceways are in point or line contact (high-performance series). Compared to deep groove ball bearings, its contact stress is lower, and it can effectively disperse composite loads, extending fatigue life.
Seal and lubrication compatibility: Most models can be equipped with dust covers (ZZ) or rubber sealing rings (2RS), achieving long-term sealing with grease lubrication, reducing the intrusion of external impurities, and suitable for maintenance-free conditions.

Main application scenarios:

It is widely used in precision machine tool spindles, high-speed centrifuges, automotive wheels and gearboxes, industrial pumps, air compressors, and power tools, etc., which have high requirements for rotational accuracy, speed and rigidity in mechanical equipment. It provides stable support for precision transmission systems.

Thrust Ball Bearing

A thrust ball bearing is a separate-type bearing specifically designed to withstand axial loads. It consists essentially of a shaft washer, a housing washer, and a ball and cage assembly. With a nominal contact angle close to 90°, it cannot resist radial loads. Classified by the direction of force, it is available as single-direction and double-direction types, suitable for single and double axial force scenarios respectively. Certain models with spherical seat washers feature self-aligning capability to compensate for installation errors.

Structure and Features:

Separate Design: The shaft washer, housing washer, and ball and cage assembly are separable, facilitating easy installation, disassembly, and maintenance, making it ideal for frequently serviced applications.
Two Core Types: The single-direction type (comprising one shaft washer, one housing washer, and one set of balls) only supports unidirectional axial force; the double-direction type (comprising one shaft washer, two housing washers, and two sets of balls) can withstand bidirectional axial force with the central shaft washer operating in tandem.
Self-Aligning Adaptability: Models with spherical seat washers can automatically correct minor misalignments between the shaft and the housing, reducing installation difficulty and improving operational tolerance.
Load Transmission Mechanism: Balls roll along the raceways of the shaft and housing washers. The point contact design distributes axial loads, balancing load capacity and running precision.
Speed Characteristic:Due to the contact mode of the rolling elements, the limiting speed is relatively low, making it suitable for medium and low-speed operating conditions.

Main application scenarios:

Widely used in medium and low-speed mechanical equipment requiring axial load support, such as crane hooks, vertical water pumps, centrifuges, jacks, and low-speed reducers, it provides reliable support for axial positioning and stable operation of equipment.

Needle Roller Bearing

Needle Roller Bearings are radial bearings that use long and thin needle rollers as rolling elements. With an elongated cylindrical shape, featuring a small diameter and a large quantity, they enable high-density support within an extremely compact installation space.

Structure and Features:

Slender Needle Roller Design: The needle rollers have a large length-to-diameter ratio (usually ≥3), featuring numerous contact points and extremely high load density.
High Rigidity & Compact Space Adaptability: Despite their small size, these bearings exhibit high radial load capacity, making them ideal for equipment structures with limited space.
Common Thin-Section Outer Ring Structure: The outer rings are often of the thin-shell type, which can fit directly against the housing bores to save axial space.
Rich Cage Type Options: Commonly used cages include stamped steel, machined metal, and plastic, suitable for high-speed, low-noise, or cost-effective solutions respectively.
Low Friction & Long Service Life:Precision-trimmed needle roller profiles and low surface roughness ensure smooth operation with minimal wear.

Main application scenarios:

Widely used in automotive engines, transmissions, steering systems, agricultural machinery, power tools, small motors, and various space-constrained transmission devices. Leveraging their small size and high-strength support, they play a key role in high-load and compact structures.

Self-aligning roller bearing

The core of the self-aligning roller bearing is designed to withstand extremely large radial loads, as well as certain bidirectional axial loads. It has the ability to automatically compensate for the misalignment error between the shaft and the seat hole, and is widely used in equipment with harsh working conditions, heavy loads, and impact.
