Our company is proud to present two types of high-quality bearings: the spherical roller bearing and the new generation ball mill bearing. These bearings are designed to deliver maximum performance, reliability, and durability, making them ideal for a wide range of industrial applications.

Spherical Roller Bearing

Our spherical roller bearings are top-of-the-line products that feature a unique design that allows for easy installation and minimal maintenance. They are made from premium materials that guarantee a long service life and minimal downtime.These bearings are ideal for use in high-speed applications, where they provide excellent load-carrying capacity, resistance to shock and vibration, and precise positional accuracy. They are also highly resistant to wear, corrosion, and lubrication contamination.

New Generation Ball Mill Bearing

Our new generation ball mill bearing  are the latest evolution in bearing technology, offering even greater performance, efficiency, and reliability than ever before. They feature state-of-the-art materials and design, such as advanced polymer materials and improved lubrication systems.These bearings are specifically designed for use in high-speed, high-power industrial applications, such as ball mills and other grinding equipment. They are engineered to deliver exceptional load-carrying capacity, resistance to wear and corrosion, and precise positional accuracy.


Our spherical roller bearings and new generation ball mill bearings are among the finest products available in the market today. They offer superior performance, reliability, and durability, making them ideal for use in a wide range of industrial applications. If you are looking for high-quality bearings that can deliver exceptional results, look no further than our product line.

Advantages of new bearings compared to traditional self-aligning rollers:


 Spherical Double Row Roller Bearings

Spherical Roller Bearing


1.The barrel of the mill must have a certain inclination, and the outer ring with a radian is designed to adjust the inclination and misalignment of the mill.2. Thermal expansion and contraction occur during mill production, and the inner ring is designed without ribs, which solves the problem of thermal expansion and contraction encountered in the production process of the mill due to high material temperature and regional temperature differences.3.The mill is fixed: the discharge end is designed with double gears, which satisfies the positioning function of the mill barrel and makes the operation more stable. The feed end adopts a design without ribs, which meets the telescopic function of the mill cylinder, and the running resistance is smaller.4. Mill bearing lubrication: The outer ring of the bearing is designed with 3 positioning holes, and each hole has an oiling thread. It is more convenient for users to lubricate the problem. 1. The centering of the inclination of the mill is completed by the self-aligning of the arc-shaped raceway of the self-aligning roller bearing.2.It does not have telescopic function, and is suitable for constant temperature environment and non-temperature materials.3. The inner ring of the self-aligning roller bearing used at both the inlet and outlet ends of the mill has double gear sides, both of which have the positioning function. There is no axial sliding function.4. The self-aligning roller has three oil holes

Load Capacity

The mill is subject to high radial load: we use two rows of linear raceway design, with more contact surfaces to carry high load and reduce impact load, so as to achieve the bearing weight and impact load required by the mill. The spherical roller bearing raceway is an arc-shaped contact surface with a small contact area. Large mills have limited weight load capacity.

Life Span

The service life can generally reach 10-12 years. The general service life of spherical roller bearings is 3-5 years

Energy saving

The double raceway design has smaller running resistance and significantly lower starting resistance, which can save electric energy; it is convenient for maintenance and saves a lot of water resources. The energy-saving effect of the curved raceway contact surface is not obvious
