Ball/Roller Bearings

Minimize friction

Bearings are an important mechanical component in motion systems, helping to reduce friction and support loads between rotating surfaces. They consist of main components: inner ring, outer ring, balls (or rollers), cage and lubricant.

Ball Bearings

Ball bearings are a type of rolling bearing with point contact, featuring spherical raceways on both the inner and outer rings. This design ensures even load distribution, reduces friction, and minimizes wear. It allows the bearing to operate smoothly at high speeds, handle significant radial loads, and, in some cases, support bidirectional axial loads when properly installed.

Thanks to their optimized mechanical properties, ball bearings are widely used in gearboxes, electric motors, industrial machinery, conveyors, and various precision equipment requiring long-term stable operation.

Thrust Bearings

Thrust roller bearings are a type of rolling bearing with face contact, specifically designed to withstand high axial loads while reducing friction and evenly distributing forces across the contact surface. Their optimized raceway structure ensures stable operation even under extreme pressure, making them suitable for applications requiring single or bidirectional axial load support.

With high load capacity and a versatile design, thrust roller bearings are widely used in gearboxes, screw shafts, presses, and power transmission systems that demand exceptional stability and durability.

Cylindrical Roller Bearings

Cylindrical roller bearings feature linear raceways on both the inner and outer rings, optimizing their ability to support high radial loads while minimizing friction. With a larger contact area compared to ball bearings, these bearings provide excellent load distribution, reducing wear and enhancing durability in high-speed and heavy-load applications.

Available in single-row, double-row, and multi-row configurations, cylindrical roller bearings are widely used in gearboxes, electric motors, heavy industrial machinery, and power transmission systems that require high precision, efficiency, and load-carrying capacity.

Spherical Roller Bearings

Spherical roller bearings have two rows of symmetrical rollers, allowing for self-alignment and even load distribution, reducing the effects of misalignment and vibrations during operation. This design enables spherical roller bearings to handle extremely high radial loads and partially accommodate axial loads, ensuring reliable performance under heavy load conditions.

With a robust structure and high adaptability, spherical roller bearings are widely used in heavy industries such as compressors, crushers, steel rolling mills, conveyors, mining equipment, and mechanical systems that require exceptional durability and load-bearing capacity.

Bearing Units

As a crucial component in the power transmission system, the bearing housing helps secure and support the rotating shaft, ensuring stability during operation. Its robust design reduces vibrations, minimizes wear, and evenly distributes the load on the bearing, thereby extending the system’s lifespan.

With high durability and excellent load-bearing capacity, bearing housings are widely used in industrial applications such as conveyors, electric motors, manufacturing machinery, and mechanical equipment. One-piece bearing housings are suitable for medium loads, while split bearing housings are ideal for heavy loads and harsh working environments.
