ABOUT US

Cylindrical Roller Bearing

The spherical roller bearing has two rows of rollers, the outer ring is a spherical raceway, and the inner ring has two raceways inclined at a certain angle relative to the bearing axis. The bearings are self-aligning and are therefore less susceptible to misalignment of the shaft and housing and bending or deformation of the shaft.

Spherical Roller Bearing

Tapered Roller Bearing

Performance comparison of four bearing materials: ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), silicon nitride (Si3N4) and zirconium oxide (ZrO2). As an important mechanical foundation, ceramic bearings are leading the world of new materials due to their excellent performance that metal bearings cannot match, such as high temperature resistance and super strength.

Deep Groove Ball Bearing

Cylindrical Roller Bearing

The rollers of cylindrical roller bearings are usually guided by two ribs of a certain ring, and the cage, roller and guide ring form an assembly that can be separated from another ring, which is a separable bearing. This type of bearing is more convenient to install and disassemble, especially when the inner and outer rings are required to have an interference fit with the shaft and shell. Such bearings are generally only used to bear radial loads, and only single-row bearings with ribs on the inner and outer rings can bear small constant axial loads or large intermittent axial loads.

Spherical Roller Bearing

Tapered roller bearing are mainly suitable for bearing combined radial and axial loads mainly in the radial direction, while tapered roller bearings with large taper angles can be used to bear combined radial and axial loads mainly dominated by axial loads. Type bearings are separable bearings, and their inner ring assembly (including tapered rollers and cages) and outer ring can be installed separately. The radial clearance and axial clearance of the bearing can be adjusted during installation and use, and it can also be pre-interference installed.

Tapered Roller Bearing

Different from other bearings, the insert spherical bearing is a deep groove ball bearing designed to work under combined radial and axial load conditions. The characteristic of this type of bearing is that the surface of the outer ring is spherical and has self-aligning ability. A typical bearing refers to a rolling assembly consisting of rings, balls/rollers, and cages. However, special "case" implementations of nodes take a completely different layout and are optimized for an extended range of tasks.

Spherical Plain Bearing

Needle Roller Bearings and Related Combined Bearings

Needle roller bearings are assembled with many slender needle rollers whose length is 3 times to 10 times the diameter. The structure is compact. The diameter of the inscribed circle of the needle rollers is relatively close to the outer diameter of the bearing, so it has a large radial load capacity.

Pillow Block Ball Bearing

The outer spherical ball bearing with seat is composed of an outer spherical ball bearing with seals on both sides and a cast (or stamped steel) bearing seat. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the outer ring of this type of bearing has a convex spherical outer surface, which can be self-aligning when matched with the concave spherical surface of the bearing seat. Usually there is a gap between the inner hole of this type of bearing and the shaft, and the inner ring of the bearing is fixed on the shaft with a top screw, an eccentric sleeve or an adapter sleeve, and rotates with the shaft. Bearings with housings are compact in structure and easy to assemble and disassemble. They are suitable for simple support and are often used in mining, metallurgy, agriculture, chemical industry, and conveying machinery.

Bearing maintenance is a crucial aspect of ensuring the longevity and performance of your bearings. Proper maintenance not only extends the service life of the bearings but also prevents unexpected failures that can lead to costly downtime. As a professional bearing supplier, we understand the importance of bearing maintenance and are here to provide you with some key tips on how to effectively maintain your bearings.

Cylindrical Roller Bearings

2023-08-22

Cylindrical roller bearings are a common rolling bearing, mainly used to bear radial loads. It is composed of inner and outer cylindrical surfaces, rollers and cages. Cylindrical roller bearings have the advantages of simple structure, large load capacity, and small friction coefficient, and are widely used in mechanical equipment.

A power ball bearing is a device used to propel a power ball to rotate. It consists of a metal shaft and several small balls. The length of the bearing usually depends on the size of the force ball, generally ranging from a few centimeters to more than ten centimeters.

Self-aligning Ball Bearings

2023-08-22

Self-aligning ball bearings are commonly used rolling bearings. The ballways of the inner and outer rings are arc-shaped, which can withstand large radial and axial loads. Self-aligning ball bearings are suitable for applications where high speed operation, bearing tilt, large axial clearance, or heavy loads are required.
