Spherical Roller Bearings Introduction
     Spherical roller bearings have two rows of raceways in the inner ring, the outer ring is spherical rolled to, the center of the outer ring raceway surface and the center of the bearing. Because of the automatic centering performance, can compensate for the installation error between the shaft and the shell hole or the shaft deflection makes the inner and outer ring tilt. This type of bearings to withstand radial load capacity is greater, but also can withstand either direction of the axial load, but can not withstand pure axial load. Especially suitable for heavy load or vibration load under the work.

MB

    This product is made of machining brass, split cage, inner ring with the overall center edge , guided by the inner ring. Under heavy load, impact load vibrafion and other working conditions, the bearing still be tough and durable.

CC

    The product adopts the stamping steel plate cage,and the end face is unblocked. The inner ring of this series of bearings has no center edge, and the cage is separated roller. This effectively reduces internal friction of the bearing, assists the rolling body under force to enter correctly into the load area, and also improves the bearing limited speed.

CA

    This product adopts machining integrated cage, without center edge in the inner ring. The end face has two small edges, and rollers are symmetrical, low noise and has a certain self-lubricating function.

MA

    The product is made of machining brass cage. Its brass solid body cage is integral center edge with inner ring and guided by outer ring.It is mainly used in in vibrating screen and other equipment.

E1

    The product adopts high strength steel plate--E1 cage.The two racks are separated by a guiding inside the outer ring. The number, length and diameter of the rollers are the maximum allowed by the structure. The close contact between roller and raceway ensures fair pressure distribution so as to make the bearing have high capacity.
 

Matters Need Attention
    Rolling bearings are precision components, their use must also be appropriate caution. No matter how high-performance bearings, if used improperly, it will not get the expected performance, relevant bearing Cautions below.
    1. To keep their surroundings clean bearings
Even tiny invisible dust into the bearing, will increase wear, vibration and noise of the bearing. Bearing and its surrounding attachments should be kept clean, especially dust and dirt, tools and working environment must be kept clean.
    2. When using the installation should carefully
Does not allow a strong punch, does not allow direct bearing percussion hammer is not allowed to pass through the rolling pressure.
    3. Using a suitable, accurate installation tool
Try using a dedicated tool, try to avoid the use of cloth and short fibers such things.
    4. Prevent bearing corrosion
    Direct hand pick bearings, to fully wash hands sweat and coated with high-quality mineral oil before operation,especially in the rainy season and summer mainly rust. However, under the operating conditions of a particular case, the longer the life the bearing can be obtained in traditional computing, especially under light load conditions. These particular operating condition is, when the rolling surface (and the rolling member rolling path) is effectively split, and limitations as the lubricant film surface contaminants may lead to damage. ln fact, under ideal conditions, the so-called permanent bearing life is possible.
