Best Price Natb 5903 Combined Needle Roller Angular Contact Ball Bearing

Welcome to SHAOXING SHANGYU FLIGHT SEIKO MACHINERY CO.,LTD !We offer a wide variety of precision machining capabilities including high quality precision machined parts, Mechanical assemblies,and cutom fabrication for automobile,textile machinery,construction machinery etc. Our manufacturing and process capabilities are ISO9000 Certified.   Heavy duty needle roller bearing is composed of one or two rings and needle roller group with cage. According to different applications, it can be divided into bearings with or without inner rings. Therefore, the solid ring needle roller bearing can meet the requirements of light weight, small space occupation and high power transmission. The solid ring needle roller bearing has smaller volume and higher bearing capacity. Structure type outer ring double rib (or double lock ring) with cage needle roller bearing Na, NAV, NKI type can be respectively installed with inner ring and outer ring (with lock ring, full set of needle roller and cage), with high authorized speed, which can be divided into single row and double row. If the shaft cannot be used as a raceway, i.e. if it is not possible or economical to grind the shaft for hardening, this type of needle roller bearing with inner ring can be used Characteristic of heavy duty needle roller bearingDesignationShaftMassDimensions(mm)Basic Load RatingsLimitingP.No.Diameter FWDCrCrCorSpeed mmg   Min.KnKnrpmNK 5/10TN53.1510100.152.5237000NK 6/10TN64.7612100.152.332.233000NK 6/12TN65.7612120.153.33.4533000NK 7/10TN76.9714100.33.333.1531000NK 8/12TN88.7815120.34.14.329000NK 9/12TN910.3916120.34.755.328000Custom size requirement are also available  Our advantage:1.The original 100% factory, more than 10 years' production experience2.Produce and process products according to your drawings and requirement.3.All kinds of surface treatment available,such as anodizing,power coating,painting,polishing and etc.4.Our professional R&D and QC team can strictily control the product quality to meet your requirement.5.Our products are of high quality at cheap price,and delivered on time.  Manufacturing strength & Vehicle processing line1.Professional operators2.Adopting advanced CNC machine tools in Japan3.Totally enclosed production workshop4.Experienced managers5.Digital control production line6.Advanced level of technology  Production Detection1.Complete testing facilities2.Perfect measurement methods3.Perfect production detection methods4.Strong QC team,conduct comprehensive quality control   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
