ZWZ spherical roller bearing

Wafangdian Bearing Group Co.,Ltd was established in 1938(ZWZ spherical roller bearing has very large market share in the world),its also named Wa zhou in China bearing market,as the birthplace of China's Bearing industry, wafangdian bearing group is the biggest bearing manufacturer in China,ZWZ is its register trademark,which is ranked top 8 of the world bearing industry,as the first bearing brand in China,its key products is Major technical equipment bearing,Rail Bearing,Vehicles bearing,wind power new energy bearing,high precision Machine and high precision ball screw,high precision Large forgings,and now ZWZ have 8 production bases all over the world,23 bearing manufacturer, With state-level enterprise technical centers,National bearing testing centre and the only large national bearing engineering technolgoy research centre in China Bearing Industry.

Spherical roller bearing is the most influential bearing type of ZWZ brand,it can produce inner ring 30-2000mm,outer ring 68-2700mm spherical roller bearing,precision level P0,P6,P5 also available in ZWZ,spherical roller bearing also named self-aligning roller bearings by some countries or area,this type of bearing are widely used in Mining machinery, paper-making machinery,shipbuilding, textile machinery, Mill, power etc., for customer to know more about spherical roller bearing character,XRB introduce some spherical roller bearing cage suffix as follows:

CA     One piece machined brass cage,no middle rib in the inner ring,but two little rib,symmetrical rollers,these design are large and medium dimension spherical roller bearing,its the most used type in spherical roller bearing
 
CAF1 the same design with CA,carbon steel cage
CAF3 the same design with CA,Ductile solid cage
CAC   the same design with CA,Curvature Optimization of the rings
ACA   no middle rib of the inner ring,with two small rib,symmetrical rollers and one piece cage with movable Spacer.
CB    with middle rib and small rib in the inner ring,two pieces cage,symmetrical rollers
C       this design is spherical roller bearing with symmetrical rollers,no rib of the inner rings,pressed steel.

ZWZ spherical roller bearing have cylindrical bore and tapered bore, 240/241/248/249 series spherical roller bearing is tapered bore 1:30,suffix K30, the other spherical roller bearing with tapered bore 1:12,with suffix K.
 
CAB CA type spherical roller bearing,Central perforation of the rollers,with Pillar cage.
CABC CAB type spherical roller bearing,improved roller guided(Roller surface roughness,Raceway surface roughness,Optimization of heat treatment method),this design can Reduce friction.

C3  Radial internal clearance greater than Normal 
C4  Radial internal clearance greater than C3 
C9  Clearance is defferent with standard 
D   split spherical roller bearing
P5  Dimensional and running accuracy to P5 tolerance class 
P6  Dimensional and running accuracy to P6 tolerance class 
HC  rings and element or rings or element are made of carburizing steel
HCR the rings are made of carburizing steel
K   Tapered bore, taper 1:12 
K30 Tapered bore, taper 1:30
L   Light Alloy solid cage
N   Snap ring groove in the outer ring
NR  Snap ring groove in the outer ring, with appropriate snap ring
Q1  Aluminum,Iron,Manganese brass cage
2RS with Steel skeleton NBR sealed bearing,double side
2RS2 Both sides of the steel skeleton Viton seals 

As one of China bearing manufacturer. XRB spherical roller bearing focus on learned high technology and knowledge from the worldwide spherical roller bearing manufacturer from 1998,and until now,XRB can produce the full-line sealed spherical roller bearing,bearing for vibrating screen equipment,warmly hope the customers from worldwide contact with XRB for sealed spherical roller bearing.

22216E bearing

Related bearing:SKF 22216E bearing,SKF bearing 22216E,22216CC/W33,22216 BEARING bearing size SKF spherical roller bearing 22216 dimension bearing inner diameter 80mm bearing outer diameter 140mm bearing width 33mm CXRB BEARING is 22216 china bearing manufacturer, factory,supplier and exporter, we focus on produce spherical roller bearing 22216,The design (cage)of spherical roller bearing :CAK/W33,E,E1,EAE4,CC/W33,EAS.M,C,MB/W33,BS 22216 bearing design and applincation 22216 Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. 22216 bearings are widely used in Papermaking machinery, railway vehicle axle, rolling mill, roller gearbox, crusher,vibrating screen, printing machinery,woodworking machinery,industrial reducer,mine.and 22216 bearing are popular size that could be used in many applications. Also we deal in world famous brand bearing like SKF bearing 1.SKF bearing Group adopted ONLY High quality GCR-15 chrome steel . 2.SKF 22216 bearings are all produced according to ABEC-1,ABEC-3 strictly. 3.100% testing before shipment, 4,ISO 9001 certificate 5.highly skilled technical staff and advanced testing equipment Advantage of SKF 22216 spherical roller bearings 1.competitive price 2.many years experience cooperation with SKF,FAG,NSK,NTN,TIMKEN,KOYO,NACHI,SNR,ZKL,ZWZ,HRB etc. 3,Strong production capacity can make sure the delivery the goods as soon as possible 4.Reliable operation quality if you have demand for SKF spherical roller bearing 22216,please contact with brandbearings@gmail.com
