Product Description 21312W33 High Precision Spherical Roller Bearing for Paper Making Machines Factory Direct Supply Application Continuous Casting Machines Mechanical Fans and Blowers Gearbox and Pumps Wind Turbines Material Handling Marine Propulsion and Offshore Drilling Mining and Construction Equipment Pulp and Paper Processing EquipmentA spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permitsangular misalignment. Typically these bearings support a rotating shaft in the [bore] of the inner ring thatmay be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internalshape of the outer ring and spherical rollers.Despite what their name may imply,Spherical roller bearings are not truly spherical in shape. The rollingelements of spherical roller bearings are mainly cylindrical in shape,But have a profile that makes themappear like cylinders that have been slightlyover-inflated. Spherical roller bearing used in countlessindustrial applications, where there are heavy loads, moderate speeds and possibly misalignment.Bearing Steel Double Row Spherical Roller BearingProduct NameSpherical Roller BearingPrecision RatingP6, P0, P5, P4, P2MaterialBearing Steel (GCr15)ClearanceC0 C1 C2 C3Vibration & NoisyZ1,Z2,Z3 V1,V2,V3CageBrass, Nylon, SteelSealZZ, 2RSFeaturesHigh Precision, High Speed, Long Life, High Reliability, Low Noise , Reduce FrictionCertificationISO 9001:2008Packing1.Neutral Packing Bearing 2.Industrial Packing 3.Commercial Packing Bearing 4.CustomizeDelivery Time30 - 45 Days After The Order is ConfirmedShippment1.By Sea 2.By Air 3.By ExpressModelBoundary Dimensions (mm)Basic Load Rating (KN)MassdDBCCoKg2130721307K21307W3335802170.7073.300.5472130821308K21308W3340902387.6092.000.7512130921309K21309W334510025105.00112.001.0102131021310K21310W335011027121.00129.001.3002131121311K21311W335512029141.00152.001.6602131221312K21312W336013031165.00175.001.9902131321313K21313W336514033186.00197.002.4502131421314K21314W337015035206.00223.002.9802131521315K21315W337516037249.00270.003.6302131621316K21316W338017039272.00306.004.2902131721317K21317W338518041297.00351.005.1902131821318K21318W339019043320.00387.006.0902131921319K21319W339520045366.00500.007.1502132021320K21320W3310021547397.00546.008.8102132221322K21322W3311024050460.00634.009.460 About UsHENGLI Machinery Company is a well-established Chinese bearing supplier. We design, manufacture andwholesale bearings. Our specialized manufacturer of Spherical Roller Bearing & Cylindrical RollerBearing, LUAN Rolling Bearing Co., Ltd was established in 1970 and is accredited by the Chinese Ministryof Machine Building.We invested in two additional specialized bearing factories, which allow us to provide our clients with top ofthe line products such as Needle Roller Bearings, Cam Follower Bearings, Thrust Bearings, SphericalPlain Bearings,Rod Ends Bearings, Ball Joint Bearings, Tapered Roller Bearings, Wheel Hub Bearingsand Non-Standard Bearings. FAQQ1 - What is our advantages? A - Manufacturer - Do it only with the Best; -Your Choice make different. Q2 - Our Products A - Spherical Roller Bearing, Cylindrical Roller Bearing, Needle Roller Bearing, Cam Followers, Thrust Bearing - Spherical Plain Bearing, Rod End, Ball Joint, Wheel Hub, Tapered Roller BearingQ3 - Process of our production A - Heat Treatment - Grinding - Parts Inspection - Assembly - Final Inspection - PackingQ4 - How to customize bearing(non-standard) from your company? A -We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.Q5 - What should I care before installation? A - Normally, the preservative with which new bearings are coated before leaving the factory does not need to be removed; it is only necessary to wipe off the outside cylin-drical surface and bore, if the grease is not compatible with the preservative, it is necessary to wash and carefully dry the bearing. -Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.Q6 - How to stock and maintenance my bearings right? A - Do not store bearings directly on concrete floors, where water can condense and collect on the bearing; -Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity or sudden and severe temperature changes that may result in condensation forming; -Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
