Product Description

High Speed Spherical Roller Bearing 23121 23121C 23121N
                                                     
Product description:Spherical roller bearing is in the two race between inner ring and groove for spherical outer ring, assembly cylindrical roller bearing.Spherical roller bearing has two columns of roller, mainly bear radial load, but also can carry axial load in either direction.Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can't afford to pure axial load.This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error.
Has two columns symmetric spherical roller type, there is a share of the spherical raceway outer ring, inner ring has two tilted to the bearing axis.
Angle of the race, has a good heart performance, when the axial stress bending or install different heart bearings can still be used normally, so vary with different bearing size series, generally allowed by the self-aligning Angle from 1 to 2.5 degrees, the type of bearing load capacity is larger, besides can bear radial load bearing can withstand the axial load, two-way role has good shock resistance, typically spherical roller bearing is allowed to work speed is low.
Self-aligning roller bearing press roller cross section shape is divided into symmetric form spherical roller and asymmetric form spherical roller two kinds of different structure, asymmetric spherical roller bearings belong to the early products, primarily for the host service, a new design when the host is rarely choose symmetric spherical roller bearing, the internal structure after comprehensive improvement design and parameter optimization, compared with the early production of spherical roller bearings, able to bear a greater axial load, the bearing operating temperature is low, so it can adapt to the requirement of high speed, according to the inner ring with or without rim and retainers used different could be divided into two kinds of type C and CA, C type bearing inner ring is the feature of no guard and USES the steel plate stamping cage, the CA model, Ryan bearing is on both sides of the inner ring has the characteristics of guard cage and used car system entities.In order to improve the bearing lubrication, can provide the user with outer ring with a ring groove and oil hole of the three spherical roller bearing, expressed as a rear bearing code/W33.According to the requirement of the user can also supply with spherical roller bearing inner ring oil hole, in order to facilitate customer handling and replace bearings, also can provide the inner hole of bearing, spherical roller bearing with taper cone hole taper 1:12, later nicknamed K said, in order to meet the user's special requirements are available within the hole taper bearings for 1:30, code-named K30 thereafter.Inner hole of the tapered bearing lock nut will be available bearing directly on the conical journal, also can with tight sleeves or withdrawal sets will be installed on the cylindrical journal bearing.

Features:Spherical roller bearings can bear radial load, and at the same time can also carry axial load in either direction.Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can't afford to pure axial load.This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error.

Application :Main applicable cage:Stamping steel reinforced cage (suffix E, domestic few).Stamping steel plate type cage (suffix CC), glass fiber enhanced polyamide 66 cage (suffix TVPB), machining of brass plate cage (suffix MB).Machined brass one-piece cage (suffix CA) stamping steel cage, vibration occasions (suffix JPA).Vibration occasions brass cage (suffix EMA).On the same structure, bearing code or have different.
Main use:Papermaking machinery, speed reducer, railway vehicle axle, gear box bearing, rolling mill rolling mill rolls, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical arrange ushering self-aligning bearing.
