Description：

The Spherical Roller Bearing  has a double row of rollers, with one common spherical raceway in the outer ring and two raceway in the inner ring and inclined at an Angle relative to the bearing axis. This ingenious structure makes it self-aligning, so it is not easy to be affected by the Angle of shaft and bearing box on the error or shaft bending, suitable for installation error or shaft deflection caused by Angle error. The bearing can bear radial load as well as bidirectional axial load.

Main applications of spherical roller bearing:

Papermaking machinery, reducer, railway vehicle axle, rolling mill gearbox bearing seat, rolling mill roller, crusher,vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical self-aligning bearing with seat.

According to user requirements, spherical roller bearings with inner ring oil holes can also be supplied. In order to facilitate the installation and replacement of bearings by customers, spherical roller bearings with taper inner holes can also be provided.The taper hole taper is 1:12. , The suffix code is K to indicate that in order to meet the requirements of special users, bearings with an inner hole taper of 1:30 can also be provided, and the suffix code is K30. Bearings with a tapered inner hole can be directly mounted on the tapered journal with a lock nut, or can be mounted on the cylindrical journal with the aid of an adapter sleeve or a withdrawal sleeve.

Materials

Bearing rings and rolling elements can be made of a number of different materials, but the most common is "chrome steel", (high carbon chromium) a material with approximately 1.5% chrome content. Such "chrome steel" has been standardized by a number of authorities, and there are therefore a number of similar materials, such as: AISI 52100 (USA), 100CR6 (Germany), SUJ2 (Japan) and GCR15 (China).

Some common materials for bearing cages:

• Sheet steel (stamped or laser-cut)
• Polyamide (injection molded)
• Brass (stamped or machined)
• Steel (machined)

The choice of material is mainly done by the manufacturing volume and method. For large-volume bearings, cages are often of stamped sheet-metal or injection molded polyamide, whereas low volume manufacturers or low volume series often have cages of machined brass or machined steel. For some specific applications, special material for coating (e.g. PTFE coated cylindrical bore for vibratory applications) is adopted.
