Spherical Roller Bearings
Spherical roller bearings are self-aligning, double-row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element. The outer ring contains a spherical race which allows for some misalignment of the shaft and housing.

Spherical roller bearings are unequalled in their capacity for high loads and tolerance to shock loads, but have limited speed capabilities. They perform consistently, even under conditions of extreme speed, 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 thorough-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or thorough-hardened by conventional heating methods.
EA, C, CD, CA, which are designed for high load capacity, are available. Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages. Type EA has especially high load capacity, features low torque, and has a high-strength cage.
An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.
To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.

Specifications:

Ability to carry heavy loads
Less coefficient of friction
High limiting speed
Large size range: inner Diameter from 1mm- 750mm
Variations of structure: CC,CA,K,W33, N,NR, MB

1.      Abstract:

Spherical roller bearings are inherently self-aligning and very robust. They have two rows of rollers which make the bearings able to carry heavy loads. The present SJQ range of spherical roller bearings mainly includes CC, CA, CAE, MB and E type. SJQ can provide a wide range of sizes of several ISO Dimension Series and also includes special designs, for example, for vibrating screens and other applications. Special bearings can also be customized as required based on the standard bearings.

2.      Features:

High precision,

High speed,

Long life,

High reliability,

Heavy load and high temperature resistance.

3.      Applications:

Widely used in machine tools, heavy-duty equipment, construction machinery, oil drilling, metallurgy machinery, mine, sailing and facilities for frontiers of science
