Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the solid type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages.Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.Model NumberHK series, BK series, HK…RS series, HK…2RS series, BK…RS series, F series, FH series, MF series, HF series, HFL series, K series, K…ZW series, KZK series, KBK series, NK series, NKS series, RNA49 series,RNA69 series, NKI series, NKIS series, NA49 series, NA69 series, NA48 series, NAO series, RNAO series,RNA49…RS series, RNA49… 2RS series, RNAV series, NAV series, RPNA series, PNA series, IR series,LR series, AXK series, AXW series, RSTO series, STO series, RNA2200 series, RNA2200…2RS series,NA2200 series, NATR series, NATV series, NUTR series, PWTR series, NNTR series, KR series, KRE series,KRV series, NUKR series, NUKRE series, PWKR series, PWKRE series.Typeneedle roller bearing.Number of Rowsingle row, double row, multi row.Materialsupreme chrome steel 100Cr6.Cage Materialsteel, brass, nylon.HardnessHRC 60-64.Precision RatingP0, P6, P5.Radial ClearanceC0, C2, C3, C4, C5.Sealing Typeopen, 2RS.Greaseas per your requirement, such as Chevron SRI-2 ,Multemp PS2, Shell Alvania R2, Changcheng 2 and so on.CertificationISO 9001:2008.MarkTIK or your mark.Packagesingle box package, industrial rolled package or as per buyer's requirement.Place of OriginChina (Mainland).Features(1) high precision;(2) high speed;(3) high load carrying capacity;(4) low noise;(5) long life span.Applicationtransport machinery, CNC machine, sewing machinery, handcart, physical exercise apparatus, motorcycle,automobile, electric tool, leisure toys, textile machinery, printing machinery etc.Payment Term30% deposit, 70% is paid by TT or L/C or Western Union.Shipment timeready stock, immediate shipment.Shipping PortShanghai, Tianjin or Qingdao.Samplesfree samples are available.Bearing No.Boundary dimensions(mm)Basic load ratings(N)Limiting speeds(rpm)Mass(g)FwDCCrCorOilHK0812-2RS8121222502100190003.50HK1014-2RS10141441005000150005.20HK1216-2RS121816610070001200011.50HK1416-2RS142016610075001100014.00HK1516-2RS152116680088001000014.30HK1520-2RS1521209500114001000018.00HK1616-2RS162216720092001000015.10HK1620-2RS1622209900123001000016.80HK1625-2RS1622259900123001000017.00HK1816-2RS18241678009900920017.00HK2016-2RS202616800010100900018.80HK2020-2RS2026201270020100780023.50HK2216-2RS222816900012400780020.30HK2220-2RS2228201040020100780025.50HK2516-2RS253216980013200690027.30HK2520-2RS2532201360020000690033.10HK2524-2RS2532241790030000690039.70HK2530-2RS2532302450043000690047.30HK2820-2RS2835201140022500530036.90HK3016-2RS3037161010016200530028.50HK3020-2RS3037201620026000530039.10HK3024-2RS3037242100038500530049.70HK3516-2RS3542161010020300490036.40HK3520-2RS3542201670030500490041.10HK4016-2RS4047161100021300420041.20HK4020-2RS4047201900030500420050.20HK4520-2RS4552202030041000380057.40HK5024-2RS5058243000061000320084.00
