22311YMW33W800C4 KOYO Spherical Roller Bearing has a high load rating and self-aligning ability, therefore it is suitable for applications at low/medium speed which involve heavy load and impact.
22311YMW33W800C4 KOYO Spherical Roller Bearing comprises of barrel-shaped convex rollers arranged diagonally. Due to the raceway of its housing raceway washer being spherical, this bearing is self-aligning and can allow a certain degree of angle tilt.
22311YMW33W800C4 KOYO Spherical Roller Bearing for all bearings used in a wide variety of fields, including cars, motorcycles, electric machinery, machine tools, aerospace equipment, OA equipment and other general industrial machinery.
22311YMW33W800C4 KOYO Spherical Roller Bearing are suitable for low/medium speed applications which involve heavy or impact loading. They come with cylindrical or tapered bores and can be supplied with adapter assemblies as well as withdrawal sleeves.These bearings are divided into R, RH(R) and RHA types, which differ in internal structure. Bearings with a tapered bore can be fit and removed easily using an adapter assembly or withdrawal sleeve.The ratio of the taper is identical among all bearing series:
240 and 241 series: 1:30 (supplementary code “K30”)
Others: 1:12 (supplementary code “K”).Spherical roller bearings are available as double-row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element. The race in the outer ring is spherical in shape, which allows for some misalignment of the shaft and the housing. Spherical roller bearings are unequalled in their capacity for high loads and their tolerance to shock loads, but have limited speed capabilities. They perform consistently, even under extreme conditions, such as application-specific stress and marginal lubrication. The cage of a spherical roller bearing provides high dimensional accuracy and functionality. According to some estimates, spherical roller bearings have twice the running life of conventional bearings.Most spherical roller bearings are made of alloy steels or low-carbon steels. Chrome-plated products are also available. Some applications require the use of case-hardened or through-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or through-hardened by conventional heating methods. When low-carbon, carburized grades of steel are used, carbon is introduced after the spherical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, fatigue-resistant case and a tough, ductile core.Bore size and outside diameter (OD) are important specifications to consider when selecting spherical roller bearings. The bore size is the bearing's smallest dimension. The outer diameter includes the bearing housing, but excludes the flange. Other important specifications for spherical roller bearings include overall width, rated speed (oil), static axial load, static radial load, dynamic axial load, and dynamic radial load. Static axial and static radial loads are, respectively, the maximum axial and radial loads that bearings can withstand without permanent deformation. Dynamic axial and dynamic radial loads are, respectively, the calculated axial and radial loads under which a group of identical bearings with stationary outer rings can endure for a rating life of 1 million revolutions of the inner ring.The R-type spherical roller bearing (two piece finger type) is contributing to a quiet operation by reducing the vibration. Our spherical roller bearings are also available with the following options:
Machined bronze retainer which is ideal for higher speed operation and ensures better performance under marginal lubrication conditions.
Asymmetrical roller design, which reduces sliding friction and has less tendency for roller skew while operating (R & RR types); this type uses two sets of convex asymmetrical rollers separated by a central inner ring rib.
Symmetrical roller design (RH Type Spherical Roller Bearing) with two rows of longer symmetrical roller and only a center guide ring instead of a rib.
R and RH Type Spherical Roller Bearings are also available with lubrication holes and grooves, which optimizes lubricant capability.
Self-alignment feature accommodates up to 2 misalignments.

Bearing KOYO 22311YMW33W800C4 feature:
1. Have high radial load capacity, especially suitable for heavy duty or vibration load work, but unable to bear pure axial load. This kind of bearing's outer ring raceway is spherical shape, so its self-aligning performance is good, can compensate for the coaxiality error.
2. There are two column symmetric type spherical roller, there is a common outer spherical raceway, inner ring have two and the bearing axis inclined Angle of the raceway, has the good self-aligning properties, when axial stress bending or install different heart bearing can still normal use, adjustable mind with bearing size series vary, general allowed by the self-aligning Angle for 1 ~ 2.5 degrees, this type bearing load capacity is larger, except can bear radial load outer bearing also can withstand the bidirectional axial load, and has good impact resistance ability, generally speaking self-aligning roller bearing are allowed to work rotational speed is low.
Bearing KOYO 22311YMW33W800C4 main application:
The papermaking machinery, speed reducer, railway vehicle axle, rolling mill gear box bearing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial deceleration machine, vertical set-contained spherical roller bearing.
Bearing KOYO 22311YMW33W800C4 (23180 CCW33/23180 CAW33) has two rows of spherical rollers between the sphered raceway in the outer ring and two inner rings raceways inclined at an angle to the bearing axis. Due to the arc center of the raceways in the outer ring and the bearing center are in the same direction, as a result, shaft flexing and misalignment of the bearing seats are compensated. Spherical roller bearing can support axial forces in both directions and high radial forces. They are designed for very high load carrying capacity. Bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer or with a withdrawal sleeve. When shaft bends by force which causes the inclined between the center of inner ring and the center of outer ring, if the inclined degree not exceed 1-2.5,the bearing can work normally.
