The rolling elements of sphericalroller bearings are mainlycylindrical in shape,But have a profile that makes them appear like cylinders that have been slightlyover-inflated.Spherical roller bearing used in countless industrial applications, where there are heavy loads, moderate speedsand possiblymisalignment.Bearing Steel Double Row Spherical Roller BearingProduct NameSphericalRoller BearingPrecision RatingP6, P0, P5, P4, P2MaterialBearing Steel (GCr15)ClearanceC0 C1 C2 C3 C4 C5Vibration & 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 /confirm/iedShippment1.By Sea 2.By Air 3.By ExpressWebsitehttp://www.hlimachinery.com ModelBoundary 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 and wholesale bearings.Our specialized manufacturer ofSpherical Roller Bearing&Cylindrical Roller Bearing, LUAN Rolling Bearing Co., Ltdwas establishedin 1970and is accreditedby the Chinese Ministry of Machine Building.We invested in two additionalspecialized bearing factories, which allow us to provide our clients with top of the line productssuch asNeedle Roller Bearings, Spherical Plain Bearings, Rod Ends Bearings,Ball Joint Bearings, Tapered Roller Bearings,Wheel Hub BearingsandNon-Standard Bearings.FAQQ1 - What is our advantages? A - Manufacturer - Do it only with the Best; -Your Choice make different.Q2 - Our ProductsA - 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 productionA - 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 cylindricalsurface and bore, if the grease is not compatible withthe 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 orother 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 bearingswill not be subjected to high humidity or suddenand 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.
