Features
- Deep groove ball bearings are composed of solid inner and outer rings, cages and steel balls, which are inseparable bearings. The cages are made of nylon, stamped steel plates, etc. The product structure is simple, reliable, durable and easy to maintain. It has various designs such as single row, double row, open type and with seal. It features low friction torque and high speed, and can withstand both radial and axial loads simultaneously.
- Angular contact ball bearings are non-separable bearings, consisting of solid inner and outer rings, rolling elements and cage assemblies. The cages are made of nylon, pressed steel plates or brass. The contact angles come in various structures such as 15°, 25°, and 40°. They can withstand combined radial and axial loads and can operate at high speeds.
- Four-point contact ball bearings belong to single-row angular contact ball bearings. Compared with double-row designs, they require relatively less space in the axial direction and have a lower cost than angular contact ball bearings. The bearing consists of a solid inner ring, a separable outer ring, rolling elements and a cage. The cage is made of brass or polyamide.
- Self-aligning ball bearings are double-row non-separable bearings. This type of bearing consists of an outer ring with spherical raceways, an inner ring with cylindrical or conical bores, rolling elements and a cage assembly. Bearings can be designed in open and sealed types. It can withstand bidirectional axial and radial loads, and has a self-aligning function. The maximum aligning Angle can reach 4°, which can eliminate the influence of misaligned installation on the bearing.
- Cylindrical Roller Bearings are divided into single-row and double-row types. The inner and outer rings can be separated. Cylindrical roller bearings belong to separable bearings, which are composed of an outer ring, an inner ring, rolling elements, and a cage. To achieve greater load capacity, they can also be designed as full roller structures without cages. The cage is made of brass, steel columns or polyamide materials. According to the flange structure, it is divided into various variant structures such as N, NJ, NU, NUP, etc. The structure with the suffix “E” is a reinforced design, which can withstand greater radial loads but not axial loads.
- Tapered Roller Bearings are composed of solid inner and outer rings with conical raceways and tapered rollers with window-type pressed cages, and they are available in single-row and double-row structures. The open structure is a separable bearing, and the inner and outer rings with rolling elements and cage assemblies can be installed separately. It can simultaneously withstand relatively large combined radial and axial loads. The larger the contact Angle, the greater the axial load-bearing capacity. To avoid stress concentration, the raceways、 rolling elements and flanges are all trimmed with protrusions.
- Spherical Roller Bearings are double-row non-separable bearings, consisting of a spherical raceway outer ring, a solid inner ring and spherical rollers with cages. The inner ring has two structures: cylindrical bore and tapered bore. Self-aligning roller bearings can withstand relatively large radial and axial loads and has an automatic self-aligning function. The maximum self-aligning Angle can reach 1.5° to 2°. It can be designed in two structures: open type and with sealing.
- Thrust Bearings can be classified into various structures such as thrust cylinders, thrust cones, thrust balls, and thrust needle rollers. They are composed of shaft rings, seat rings, rolling elements, and cages. The cages are made of materials such as nylon and brass. Thrust bearings have a very small axial section height. This type of bearing can only withstand pure axial loads in one direction, has a large load-carrying capacity and high rigidity.
- Needle roller Bearings consist of needle rollers and cages, also known as needle roller cage assemblies. They come in single-row and double-row structures. The cages are made of stamped steel plates or nylon. Due to their small radial cross-section, they are typically used in very small spaces between shafts and bearing housings. This type of bearing has a high load-carrying capacity. It is suitable for high-speed and easy-to-install applications. According to the working conditions, needle roller bearings with stamped outer rings or solid outer rings can be designed.
